Snowshoe Wrightwood’s Table Mountain

FEBRUARY 20, 2019 BY CHRIS KASTEN

9,399′ high Mt. Baden-Powell’s massif dominates the southwest skyline from Table Mountain.

Joanie and I got out for a great afternoon of snowshoeing up on Wrightwood’s Table Mountain about a week and a half ago. Since then, more storms have dropped even more of the precious powder on our local mountains. Whether you like to cross-country ski or snowshoe, it’s a fantastic time to be out amongst our high country peaks, canyons and forests!

Inset of the Trails of Wrightwood – Big Pines map. The area we went snowshoeing is depicted as Table Mountain (with campground symbol) at an elevation of 7,200′. The west end of Wrightwood appears in the lower right corner of image.

Table Mountain is 7,516′ high and super easy to get to from Wrightwood. Just drive. You’re only looking at four miles from our village center. Make sure to turn off to the right on Table Mountain Road when you arrive at the three way split in the roads at Big Pines. Table Mountain Campground is where we did our snowshoeing on a quiet Friday, where we seemed to have the place to ourselves. The wind had sculpted the snow into pristine dunes along the gently sloping ridge top that the extensive campground straddles.

Joanie seems to almost float atop the powder on the sunny slopes of Table Mountain!

All the campsites were, of course, hidden under the snowy mantle, with just the picnic tabletops presenting themselves as a bit of a depth gauge. Most of the time, snow depth was around 24″ and in places well over three feet. The windward sides of the mammoth white fir and Ponderosas were coated in sparkling icicles that fell like shards of glass in the wind gusts that came out of the southwest. Mt. Baden-Powell kept constant watch over us from across the great gulf of the East Fork of the San Gabriel River. The Mojave Desert off to the north was a mosaic of tans, yellow sands and the right-angled patchwork of green winter crops scattered here and there. It looked and felt warmer down there. And high up on Table Mountain, that day was to be one of cobalt blue skies, bright white snows, wind and evergreens.

Douglas Wallflowers in Blossom

MARCH 29, 2020 BY CHRIS KASTEN

Here’s a Douglas Wallflower alongside the Upper Falls Trail, as seen this last Monday while hiking up the Big Santa Anita Canyon under cloudy skies. Our series of much-needed rain storms have brought back thick green grasses and the start to what’ll most likely be a colorful Spring of other wildflowers. Joanie and I hiked the two-mile Falling Sign Loop from Fern Lodge.

These Douglas Wallflowers (*Erysimum capitatum*) popped out at us just downstream from the double slot pools on the Upper Falls Trail. There’s also a nice grouping of wallflowers near the second bench up the road from Roberts’ Camp in San Olene Canyon.

Sturtevant Falls was tumbling down nicely. The scent of white sage peppered the cool air and the background surf-like sound of the stream followed us the whole way. We brought along an old shovel, cleaning off small slides here and there. Wild lilacs (buck brush) are still sending their mild lavender scent into the canyon breezes while the bright red orange of Indian paintbrush pokes up from the damp earth near Hoegee’s Drop-Off. And overarching along most of the route, the Laurel bay blossoms still cling to the dark green canopies. Look for the tender dark reddish purple leaves of the canyon big-leaf maples as their foliage begins to fill back in for a new season. Even the white alders are pushing out a myriad of their bright green leaflets, replacing that smokey look of dormancy with new life.

View looking east up into the East Fork of Big Santa Anita Canyon from Gabrielino Trail. Note the Toyon in the foreground, still hanging onto some of its’ red berries. That’s Rankin and Monrovia peaks in the most distant background. Clamshell Peak is barely captured on the right hand side of photo.

Western Fence lizards are out at Tin Can Point

This turquoise colored fence lizard (Sceloporus occidentalis) was seen out in the warmth of early Spring at Tin Can Point. Tin Can Point is just up from Fern Lodge Junction on the Gabrielino Trail. It’s the first switchback you’d encounter after the trail passes through the canyon live oak forest and then enters the chaparral, just a few minutes up from the trail junction.

A beautiful fence lizard basks in the gentle warmth of early Spring at Tin Can Point. See inset of the Chantry Flat – Mt. Wilson Trails map, below, to see where this point is. As of this writing, a cold wet pacific storm is dropping nearly six days of chilly rain and snow in much of the San Gabriel mountains. Big Santa Anita Canyon dam has received over 5 1/2″ of rain in the last week. Something I just learned recently about these Western Fence lizards is that their populations have the effect of reducing the incidence of Lyme’s disease in the ticks that live in the chaparral, such as found covering much of the slopes of the Big Santa Anita Canyon! Apparently, a protein in the lizard’s blood kills the bacterium in the tick’s gut, which is good news for hikers and even their dogs during the spring and autumn months.

Like most reptiles, Western Fence lizards hibernate, at least for a little while each winter throughout their habitats which are wide-spread throughout California. As for food, these lizards eat spiders and various insects such as mosquitos, beetles and grasshoppers. The females lay several small clutches of eggs (3-17) in the spring, the young emerging in the summer.

Indian Trails

Establishment of the ancient Indian trails.

Oasis of Mara, Joshua Tree National Park – 2006

The indigenous peoples of the Mojave Desert, such as the Mojave, Chem e huevi, Serrano, and others, developed the first trails through the desert based on a deep understanding of the natural environment, honed over generations of living in this challenging landscape. These trails were not found by accident but were carefully established routes facilitating travel, trade, and access to resources within the desert and between different ecological zones. Here are some key methods and considerations that these indigenous peoples likely used to establish the trails:

Water Sources: Finding and remembering the locations of reliable water sources was crucial for survival in the desert. Trails often connected springs, rivers, and waterholes that could sustain travelers through the arid landscape.
Landmarks: Natural landmarks such as mountains, rock formations, and distinctive vegetation would have served as navigation aids, helping to guide the way and mark progress along the trails.
Seasonal Variations: Understanding the seasonal changes in the desert, including variations in water availability and the movement of game animals, would have influenced the timing and direction of travel on these trails.
Trade and Social Networks: Trails facilitated trade and communication between indigenous groups. They were designed to connect communities and trading posts, enabling the exchange of goods, ideas, and cultural practices.
Observation and Oral Tradition: Knowledge of the landscape and its best routes would have been passed down through generations, with each generation refining and adding to this knowledge base. This oral tradition ensured that valuable information about navigating the desert was retained and shared within communities.
Adaptation to the Environment: Trails would have been adjusted and modified over time in response to environmental changes, such as the shifting of water sources or the growth of new obstacles. This adaptive approach ensured that the trails remained viable over long periods.

These trails, established through intimate knowledge of the desert environment, would later be used by European explorers, settlers, and others as they moved through the Mojave Desert. The legacy of these indigenous trail-making practices is a testament to the ingenuity and resilience of the desert’s original inhabitants.

California Grizzlies

The California grizzly bear (Ursus arctos californicus) is a subspecies of the brown bear that once inhabited various regions of California. Historically, grizzly bears were found throughout the state, from the coast to the mountains and valleys. They were an important part of California’s wildlife and played a role in the culture and folklore of indigenous peoples.

Unfortunately, due to habitat loss, hunting, and human conflicts, the California grizzly bear population declined significantly throughout the 19th century. The last known California grizzly bear in the wild was killed in 1922 in Tulare County. The species was declared extinct in 1924.

Efforts have been made to preserve the memory of the California grizzly bear, and it is often symbolically represented in the state’s flag and seal. The California grizzly bear is also the state animal, even though it no longer exists in the wild.

There have been occasional discussions and proposals for reintroducing grizzly bears to certain parts of California, but these efforts are complex and face challenges related to habitat, human-wildlife conflicts, and public opinion. As of my last knowledge update in January 2022, there were no active reintroduction programs in place. Still, it’s advisable to check for the latest information, as conservation efforts and plans may evolve.

Mojave Desert Ecological Transitions

The Mojave Desert, located in the southwestern United States, is a unique and ecologically diverse ecosystem known for its extreme temperatures, arid conditions, and distinct plant and animal life. Various factors, including topography, climate, and human activities, influence the transitions within the Mojave Desert ecosystem.

Here are some key ecological transitions within the Mojave Desert:

Elevation Gradients:
- The Mojave Desert exhibits significant elevation gradients, ranging from below sea level in Death Valley to higher elevations in mountainous regions such as the Spring Mountains and the Mojave National Preserve. These elevation changes lead to variations in temperature, precipitation, and vegetation types.
Flora and Fauna Shifts:
- Plant and animal species are adapted to specific elevation ranges within the Mojave Desert. As you move from lower to higher elevations, you may encounter shifts in vegetation types, with desert shrubs giving way to pinyon-juniper woodlands and eventually to coniferous forests.
Water Availability:
- Water availability is a critical factor influencing ecological transitions in the Mojave Desert. Oasis ecosystems, supported by underground aquifers or natural springs, provide unique habitats in contrast to the surrounding arid landscapes. These oases can support a higher diversity of plant and animal life.
Playa Ecosystems:
- Playas, or dry lake beds, are common features in the Mojave Desert. During rainfall, playas can fill with water, creating temporary wetland habitats that support a burst of life, including migratory birds and amphibians. However, these ecosystems are highly dependent on unpredictable precipitation patterns.
Human Impact:
- Human activities, such as urban development, agriculture, and infrastructure projects, have significantly altered the Mojave Desert landscape. Urban areas like Las Vegas and Los Angeles have expanded into the desert, leading to habitat fragmentation and loss. Human activities can disrupt natural ecological processes and contribute to invasive species encroachment.
Climate Change Effects:
- The Mojave Desert is not immune to the impacts of climate change. Changes in temperature and precipitation patterns can affect the distribution of plant and animal species, alter vegetation composition, and influence the timing of biological events, such as flowering and migration.
Fire Ecology:
- Fire is a natural ecological process in many ecosystems, including the Mojave Desert. Some plant species in the desert have adapted to fire, and periodic wildfires can shape vegetation patterns. However, altered fire regimes due to human activities or climate change can have complex effects on the ecosystem.

Understanding these ecological transitions is crucial for effective conservation and management of the Mojave Desert. Conservation efforts need to consider the interconnectedness of various factors and address the challenges posed by human activities and climate change to maintain the health and biodiversity of this unique desert ecosystem.
