Why I Like Geology

Soda Lake – Mojave National Preserve

I like geology because it transforms how I see the desert. Geology explains why the land looks the way it does, why water follows certain paths, why mountains rise, or basins sink, and why springs appear. It shows how natural forces shape human choices: trails, roads, mines, railroads, and settlements emerge from the land’s history. Geology turns the desert from empty space into a record that can be read.

To many people, the desert looks still and silent. They see rocks, dry washes, cliffs, playas, distant mountains, and open ground. However, geology reveals that the desert is not still at all. It is the result of movement, pressure, heat, erosion, faulting, volcanism, uplift, and time. Every ridge, canyon, lava flow, terrace, wash, spring, and fault scarp has a reason for being there. While the land may not speak plainly, it leaves evidence.

Jumbo Rock – Joshua Tree National Park

That is one reason geology appeals to me. It is based on visible proof. A geologist can look at a cliff face, a broken hillside, a tilted layer of rock, a dry lakebed, or a mine dump and begin to understand what happened. The evidence may be old, weathered, scattered, or partly hidden, but it is still there. Geology rewards careful observation. It asks a person to slow down, look closely, compare patterns, and respect what the land is showing.

For about nine years, I wandered and explored the desert simply by going out there. I moved from one point of interest to another, mostly staying to myself. Instead of following a formal course or guided route, I learned by looking, walking, comparing places, and remembering what I had seen. A canyon led to a spring. A spring led to a wash. A wash led to a road. A road led to a mine, a pass, a dry lake, or a faulted hillside. Over time, the separate places began to connect, further deepening my understanding.

Amboy Crater

That kind of wandering gave the desert time to teach me. I was not trying to master it all at once. Some places made sense right away. Others stayed confusing until I saw another place that explained them. Over time, the desert became less like a collection of isolated sites and more like one connected landscape.

Lake Manly – Death Valley

In making these connections, I began to see that geology and history both seek to explain the past, but in different ways. History asks who came through a place, what they did, what they called it, and what they left behind. Geology, in contrast, asks deeper questions: Why is this pass here? Why did the river cut through at this place? Why did the lake disappear? Why was ore found in this mountain and not another? Why did a spring appear along one route and not another? Ultimately, human history depends on the shape and structure of the earth beneath it.

Blue Cut Fault – Joshua Tree National Park

This is especially true in the Mojave Desert. The Mojave is a land of corridors, barriers, basins, mountains, playas, springs, faults, and washes. People did not move across a blank map. They followed water, passes, dry lake margins, river channels, and openings between ranges. Trails, wagon roads, railroads, highways, mining camps, and towns were all influenced by geology. To understand the Mojave well, a person has to understand the ground.

Geology also explains why the desert can feel so old. Human history may reach back a few hundred or a few thousand years, but geology reaches into deep time. It deals with ancient seas, vanished lakes, old volcanoes, buried rivers, moving faults, and mountains worn down and raised again. It reminds us that the land existed long before us and will remain long after us. That perspective gives the desert dignity.

I admire geologists because they know how to read the earth without needing it to speak plainly. They can stand before a canyon wall, a fault zone, a lava field, or a dry lake and see more than scenery. They see time, force, sequence, and evidence. They understand that the land is not random. It has structure. It has a history. It has a record, even when that record is difficult to read.

I also admire the dedication and discipline geology requires. It is not casual work. It takes field study, maps, measurements, samples, notes, old reports, and comparison. A geologist must be willing to walk rough ground, endure heat and distance, and keep looking when the answer is not obvious. The earth does not reveal its story all at once. Understanding comes one observation at a time.

That kind of work requires humility. A good geologist cannot force the land to fit an easy explanation. The evidence has to lead. If the rocks say one thing and the theory says another, the theory must change. That respect for facts is one of the strongest parts of geology. It is disciplined curiosity. It combines imagination with restraint.

The Desert Studies Center at Zzyzx belongs in this story because it represents desert study put into practice. With this focus shifting from theory to place, it is a center where students, teachers, and researchers can go into the Mojave itself and learn directly from the land. Set near Soda Dry Lake, at the end of the Mojave River system, it stands in one of the best natural classrooms in the desert.

That setting matters. Around Zzyzx are dry lake beds, springs, salt flats, rocky slopes, volcanic features, desert plants, old shorelines, and evidence of water, heat, faulting, erosion, and long-term change. A person studying there is not learning geology only as an abstract subject. He is standing inside the evidence.

The Desert Studies Center also shows why geology requires discipline. Field science is not guessing from a distance. It means walking the ground, taking notes, checking maps, and comparing what is seen with what has been written. That is the kind of work I admire. It takes order and respect for facts.

In that sense, Zzyzx is more than a place on the map. It serves as a bridge between curiosity and discipline, and as a living example of how the Mojave Desert continues to be studied and interpreted. The Desert Studies Center turns admiration for geology into practical learning. Connecting students and researchers directly with the land shows that the desert itself remains the best teacher.

Geologists also help preserve meaning in places that might otherwise be overlooked. A dry wash is not just a wash. A playa is not just a flat place. A fault is not just a crack. A mine is not just a hole in the ground. Building on this, each one belongs to a larger story. Geology connects small details to big forces. It turns scattered features into a pattern.

That is why geology makes the desert understandable. Instead of seeing emptiness, geology reveals the bones and memory of the landscape. The Mojave is not barren, but layered with evidence of violence, patience, age, movement, and history. Geology’s explanation brings order and beauty to the surface, grounded in the evidence it preserves.

I like geology because it deepens every desert visit. Once you begin to see the land geologically, ordinary places become more interesting. A roadcut becomes a lesson. A wash becomes a process. A spring becomes a clue. A mountain front becomes evidence of movement. A dry lake becomes the trace of a vanished world.

Most of all, I like geology because it sharpens attention and deepens understanding. Geology rewards patience, discipline, and respect for the past. It reminds us that the earth has a story older than our own, and the Mojave Desert, far from being empty, vividly displays that story. With geology, the desert becomes readable and meaningful.

Mojave: Nature or Nurture

If you’re wondering whether the Mojave Desert is shaped more by nature or human influence, the answer is a combination of both. However, nature has had the predominant role for much longer.

Over millions of years, nature has carved out the Mojave, sculpting its landscapes through the forces of wind and water. It has created mountain ranges, valleys, and ancient lakebeds, setting the stage with extreme temperatures, limited rainfall, and hardy plants and animals that have adapted to survive in this challenging environment. Species like Joshua trees, creosote bushes, bighorn sheep, and sidewinder rattlesnakes have all found a way to thrive in a land where survival is not guaranteed.

In contrast, humans have made their mark in a much shorter timeframe. Indigenous peoples, such as the Chemehuevi and Mojave, lived sustainably in the region, moving with the seasons and utilizing the land’s resources without depleting them. Later, settlers, miners, ranchers, railroad builders, and modern developers added further layers of change. Some areas, like Las Vegas, military installations, and sprawling solar farms, have undergone significant transformation. In contrast, other regions remain relatively untouched, preserving their raw, ancient beauty.

So, is the Mojave a product of nature or nurture? Nature formed it, while humans have made adjustments—sometimes respecting its limits and other times pushing them. Regardless of how much we build or alter the landscape, the desert continues to adhere to its own rules. Flash floods serve as reminders of the power of water, sand dunes shift and reclaim the land, and scorching summer temperatures demonstrate who is truly in charge.

Batteries Go Here

A cloaca is an opening in some animals, like birds, reptiles, and amphibians, where the digestive, urinary, and reproductive systems come together. It’s like a multi-purpose exit, handling waste and reproduction. In most mammals, these functions are separated into different exits, but in animals with a cloaca, everything comes out of the same spot.

The Mourning Dove Song

Three short, sad notes the Mourning doves call to each other from bunches of thick green leaves in the cottonwood trees. The heat pushes up the canyon, and the bright sun chases the shadows into themselves the way a mirage disappears as you approach.

Boots crunched softly in the thick sand along the trail and spotted lizards dart frantically in the low scrub. The pointed ears of a coyote catch your attention as it leaps over a clump of gray grass to pounce on a squirrel eating a seed. A tortoise marches on steadfastly and fearless in his search for a mate. A cottontail nibbles on a juicy young leaf and listens closely to every scratch and pop.

The late morning finally gives way, and high noon approaches as bold as a bully. The air is clear and hot. The sun burns the back of your hands, bringing salt to your dry lips. Your forehead tingles; you push the brim of your hat back and tilt your head forward a bit to keep your face in the shade.

Cudahy Camp, Old Dutch Cleanser, and the Wonders of Last Chance Canyon

Cudahy Camp: A Glimpse into the Past

Nestled in the El Paso Mountains, Cudahy Camp is a historical landmark in the early 20th-century mining industry. From 1923 to 1947, this site was the primary source of pumice used to manufacture ‘Old Dutch Cleanser,’ a widely known cleaning product in the United States. At its peak, the camp employed 12 men who produced 100 tons of pumicite weekly. Today, visitors can explore the remnants of the camp, including concrete foundations and large hollowed-out rooms from the mining operations.

The Evolution of Old Dutch Cleanser

Old Dutch Cleanser’s journey began in 1905 when the Cudahy Packing Company, a meatpacking firm, developed the product to repurpose animal fat. The cleanser, made by combining soap with pumicite, quickly became a household staple due to its effectiveness. The brand’s logo, featuring a Dutch woman chasing dirt with a stick, symbolized cleanliness and helped the product gain widespread recognition.

In the 1920s and 1930s, Old Dutch Cleanser was heavily promoted through advertisements and civic events like “Clean-Up Week,” encouraging community participation in cleaning efforts. These campaigns solidified the product’s place in American homes and contributed to its lasting legacy.

Corporate Changes and Present-Day

In 1955, Purex acquired Old Dutch Cleanser from the Cudahy Packing Company. The brand changed hands again in 1985 when Greyhound Corporation’s Dial division purchased Purex. Despite these transitions, Old Dutch Cleanser remained a trusted cleaning product. It is manufactured by Lavo in Montreal and continues to uphold its reputation for quality (6/2024).

Last Chance Canyon: A Scenic and Historic Site

Last Chance Canyon, part of the El Paso Mountains, is a significant historical and natural site. It offers a unique glimpse into the area’s rich mining history, including the famous Burro Schmidt Tunnel. The canyon features a rugged landscape with geological formations, box canyons, and historical mining sites. This area was heavily mined from the 1890s through the 1920s, with various operations continuing into the late 20th century.

Visitors to Last Chance Canyon can explore the remains of mining camps, such as Bickel Camp and the Holly Ash Mine, alongside the Old Dutch Cleanser mining site. The canyon is also known for its beautiful scenery, including rock-walled sandy canyons and spectacular layered cliffs.

Cultural Significance and Enduring Legacy

Old Dutch Cleanser has significantly impacted American culture, from being featured in popular media to becoming part of civic traditions. Its memorable branding and consistent advertising have made it a recognizable name in household cleaning. The El Paso Mountains and Last Chance Canyon now serve as historical sites, offering a window into the past for those interested in industrial history and heritage.

Covered Wagon (prairie schooner)

/wagons/

Covered wagons significantly impacted the United States’ westward expansion during the 18th and 19th centuries. These wagons, often called “prairie schooners,” were designed to transport goods and settlers across the North American continent.

Family & covered wagon (prairie schooner)

Key features and uses of covered wagons included:

  1. Design: Covered wagons typically had a wooden frame with a canvas cover. This cover protected the contents from weather elements like rain and sun. The wagon bed was usually made of wood and was about four feet wide by ten feet long.
  2. Cover: The cover was made of canvas or similar durable cloth, stretched over hooped frames, providing shelter and goods for the occupants.
  3. Wheels: The wheels were often large and designed to handle rough terrain. The front wheels were usually smaller than the rear wheels, allowing easier turning.
  4. Draft Animals: Oxen, mules, or horses were commonly used to pull these wagons. Oxen were preferred for their strength and endurance, especially over long distances.
  5. Role in Expansion: Covered wagons were essential for westward migration in the U.S. They carried settlers’ belongings, including tools, food, and sometimes even passengers. These wagons were a vital part of the movement to settle the American West and were commonly seen on trails like the Oregon Trail, the Santa Fe Trail, and the California Trail.
  6. Living Quarters: The covered wagon was a temporary home for many settlers traveling west. Families would cook, eat, sleep, and spend much of their time in or around the wagon during their journey.
  7. Historical Significance: The image of a covered wagon crossing the plains has become an iconic symbol of American frontier life, representing the pioneer spirit, exploration, and the challenges of frontier life.

The use of covered wagons declined with the advent of railroads, which offered a faster and more efficient means of transporting goods and people across the country. However, their legacy remains an integral part of American history and folklore.

The Von Schmidt Boundary

(1873)

The Von Schmidt boundary, or the Schmidt Line, refers to a historical boundary line in California. It was surveyed and established by Alexey von Schmidt, a Russian engineer, in the 1860s. The purpose of the Von Schmidt boundary was to delineate the border between California and Nevada during a time when there was confusion and disputes over the exact location of the state boundary.

Von Schmidt’s survey helped clarify the boundary and resolve conflicts between California and Nevada. His efforts included placing markers and monuments along the boundary line to make it clear and permanent. The boundary he established still exists today and is the official border between the two states.

The Von Schmidt boundary is of historical significance and has been preserved as a reminder of the surveying and boundary disputes of the past. It is located in the eastern part of California near the Nevada border.

Why was the initial boundary incorrect?

The initial boundary between California and Nevada was incorrect and subject to disputes for several reasons:

  1. Lack of Accurate Surveys: In the early years of California’s statehood and during the Gold Rush era in the mid-19th century, limited resources and technology were available for accurate land surveys. As a result, the initial surveys and boundary markers were not precise.
  2. Rush for Mineral Resources: The discovery of gold and other valuable minerals in the region led to a rapid influx of settlers and miners. This rush created a need for clear land boundaries and property rights. However, the focus was often on extracting resources rather than conducting precise surveys.
  3. Overlapping Claims: Different parties, including miners, settlers, and land speculators, had conflicting claims to land in the region. These overlapping claims added to the confusion regarding the exact location of the state boundary.
  4. Political Disputes: California became a state in 1850, and shortly thereafter, disputes arose over its eastern boundary. Nevada was not established as a separate territory until 1861. Political disagreements and conflicting interpretations of earlier treaties and agreements existed during this period.
  5. Multiple Surveys: Various individuals and surveyors attempted to establish the boundary, but their surveys often differed. This further complicated matters.

Given these factors, there was much uncertainty and disagreement regarding the California-Nevada boundary in the early years. It was only through the efforts of surveyors like Alexey von Schmidt and subsequent legal and political resolutions that the boundary was eventually clarified and accepted. Von Schmidt’s survey work played a crucial role in resolving these disputes and establishing a more accurate boundary line.

Aurora

Aurora, Nevada 1910

The town of Aurora, Nevada, experienced a move due in part to the boundary disputes between California and Nevada. Aurora was originally founded in the 1860s during the Nevada Silver Rush. At its founding, the exact location of the California-Nevada border was still uncertain and subject to disputes.

As a result of the boundary disputes and the fact that Aurora’s initial location was close to the border, there were concerns about which state’s jurisdiction the town fell under. Aurora’s residents and businesses moved the town slightly to the east, further into Nevada’s territory, to avoid potential legal and tax issues. This move ensured that Aurora would be firmly within the boundaries of Nevada when the border dispute was eventually resolved.

The relocation of Aurora was a strategic decision made to secure the town’s status as part of Nevada rather than California, given the uncertainties and conflicts related to the state boundary at the time. This move allowed Aurora to thrive as a mining town in Nevada without the legal complications associated with straddling the border.

Is everybody happy?

It’s difficult to determine whether “everybody” is happy, as people’s feelings and satisfaction with their circumstances can vary widely. Happiness is subjective and depends on individual experiences, perspectives, and circumstances.

In the context of the town of Aurora’s relocation due to boundary disputes, it’s possible that the decision to move was made to address specific legal and jurisdictional concerns at the time. The move may have been necessary for the town’s continued growth and prosperity. However, whether every resident or stakeholder was happy with the decision would depend on their perspectives and interests.

In any community or population, there will be a range of opinions and emotions regarding significant decisions like a town’s relocation. Some may have been happy with the move because it resolved legal uncertainties, while others may have been less pleased due to the disruption and changes associated with relocation.

To determine the current happiness or satisfaction of people in a specific context, it would be necessary to conduct surveys or interviews to gather their perspectives and opinions.

Ghost Towns & Gold Mines

Ghost Towns, Sites, and Gold and Silver Mines in the Mojave Desert

Ballarat, CA.

The Mojave Desert is known for its rich history of mining and the presence of ghost towns and abandoned mines. Here are some notable ghost towns, sites, and gold and silver mines in the Mojave Desert:

  1. Calico Ghost Town: Located near Barstow, California, Calico is one of the most famous ghost towns in the Mojave Desert. It was a thriving silver mining town in the late 1800s but became abandoned when the silver market declined. Today, it’s a well-preserved tourist attraction.
  2. Rhyolite, Nevada: Rhyolite was once a booming gold mining town in the early 1900s. It had over 5,000 people but was quickly abandoned when the mines played out. You can visit the remains of the town and see the famous “Bottle House” made of glass bottles.
  3. Goldfield, Nevada: Goldfield was another prosperous gold mining town in Nevada. It had a peak population of around 20,000 people in the early 1900s. The Goldfield Hotel and several historic buildings still stand today.
  4. Panamint City, California: This remote ghost town in Death Valley National Park was a silver mining town in the late 1800s. It’s accessible via a challenging hike and offers stunning views of the surrounding desert.
  5. Cerro Gordo, California: Cerro Gordo is an old silver mining town still privately owned. It’s located in the Inyo Mountains and has a well-preserved ghost town, including a general store, bunkhouse, and other structures.
  6. Mines in the Mojave Desert: The Mojave Desert is home to numerous gold and silver mines, many of which are abandoned. These mines contributed to the region’s mining history. Some notable mines include the Tonopah-Belmont Mine, the Desert Queen Mine, and the Goldstone Mine.

Remember that exploring abandoned mines can be dangerous due to unstable structures and the presence of toxic gases. It’s essential to exercise caution and, if needed, seek permission or guidance from local authorities or landowners when visiting these sites. Additionally, some ghost towns and mines may be on private property, so be respectful of any access restrictions.

Roads West

Mojave Road and Beale’s Wagon Road are historic routes in the southwestern United States, particularly in the Mojave Desert region. Here’s some information about each:

  1. Mojave Road:
    • The Mojave Road is a historic trail that traverses California’s Mojave Desert. It was a significant route used by Native Americans, Spanish missionaries, and later by American pioneers and traders.
    • The trail is approximately 138 miles long and extends from the Colorado River near present-day Needles, California, to the Mojave River near present-day Barstow, California.
    • It was primarily used for transportation and trade between the Colorado River and the coastal settlements in California. The trail passes through varied desert landscapes, including sandy stretches, rocky terrain, and mountainous areas.
  2. Beale’s Wagon Road:
    • Beale’s Wagon Road, named after Edward F. Beale, a military officer and explorer, was a trail developed in the 19th century for the U.S. Army to improve communication and transportation across the arid lands of the American Southwest.
    • Edward F. Beale surveyed and established the road in the late 1850s. The road ran from Fort Defiance in Arizona to the Colorado River, passing through present-day Arizona and California.
    • Beale’s Wagon Road was designed to be more reliable and accessible than other trails, facilitating military movement and communication between California and the western territories.

Mojave Road and Beale’s Wagon Road were important in the United States’ westward expansion. Today, these routes attract history enthusiasts, adventurers, and off-road enthusiasts who explore them to experience the challenges faced by those who traveled these paths in the past. Keep in mind that conditions and accessibility of these trails may vary, so it’s important to check for current information and any regulations before embarking on a journey along these historic routes.
