Following the thread of violence leading to the destruction of an Indian population.
The Four Indian Boys (Late Winter–Spring 1866)
In early 1866, four starving Indian boys, likely Paiute or Serrano, crossed the mountains with a wagon train bound for San Bernardino. When they arrived, weary and near collapse, local families welcomed them, offering food, shelter, and care. Their kindness stood out in a time when relations between settlers and Native peoples were often marked by fear and conflict. For the boys, this moment meant survival; for the community, it became a small act of reconciliation—a reminder that compassion could bridge divisions, even on a harsh frontier.
While staying in the area, one of the boys went rabbit hunting. While out in the brush, they ran into the Thomas brothers. The Thomas brothers were from El Monte, where it was tough and bullies abounded. There was a dispute, and one of the brothers pointed his pistol at the Indian boy. Thinking the other boy meant to shoot, the Indian boy raised his rifle and fired.
A hearing determined that the Indian boy had killed the other in self-defense. When news of the accident reached nearby settlers, tensions quickly rose. Fear, rumor, and resentment fueled a harsh response.
The boys were to be taken home to the desert, and the surviving Thomas brothers and their friends eagerly volunteered for the job. Rather than go through the Cajon Pass, however, the party went over the ridge line between Devil’s and Sawpit Canyons.
The Indian boy who had been involved in the shooting grew suspicious and escaped, hiding in the shadows of the narrow canyon. Another boy was killed in his attempt to flee.
The remaining two boys were taken down near the Las Flores ranch and slaughtered and mutilated as a final insult.
The Battle of Indian Hill (Spring–Summer 1866)
The killings spread anger and grief among the local Indian families in the mountains, who saw the act as unprovoked and cruel. Within weeks, a group of warriors struck back, raiding the lumber mill at Burnt Mill Creek near Crestline — the opening blow in the chain of violence that would lead, within a year, to the Battle at Chimney Rock.
In the weeks following the executions at Las Flores Ranch, anger spread among the mountain Serrano and Chemehuevi bands. The deaths of the boys were viewed as unjust, carried out in cold blood and without reason. Possibly seeking revenge, a group of warriors moved south through the San Bernardino Mountains toward a small lumber operation at Burnt Mill Creek, near present-day Crestline.
The mill was one of several frontier sawmills cutting timber for ranches and for the growing settlement of San Bernardino. At dawn, the Indian raiding party attacked, catching the workers off guard. Several mill hands were killed, and the structures were burned to the ground. The site was left smoldering — a charred ruin that gave the place its lasting name, Burnt Mill.
When word of the attack reached San Bernardino, it caused alarm throughout the foothill ranches and timber camps. Men armed themselves and organized night watches, fearing further raids. Though small in scale, the Burnt Mill episode marked the turning point when isolated resentment turned into open conflict.
From that moment, the settlers in Summit Valley and the surrounding country expected more violence — and before the year’s end, they were proven right.
The Killings of Nephi Bemis & Ed Parrish at Las Flores Ranch (Late 1866)
The tension that followed the Burnt Mill attack did not subside. By late 1866, ranchers in Summit Valley were on edge, certain that more raids were coming. Among them were William Parrish and Nephi Bemis, who operated Las Flores Ranch, one of the most significant and most isolated properties in the valley.
When word spread that Indians had been seen again in the surrounding hills, Parrish and Pratt refused to abandon their post. They stayed behind to guard their livestock and property, while others left to summon help from San Bernardino. Sometime soon after, a band of Indians appeared at the ranch. Accounts differ on how the meeting began — some say they approached peacefully, others that they came under the guise of trade — but before long, gunfire erupted.
When riders returned from San Bernardino, they found both Parrish and Pratt dead, the ranch looted, and stock driven off into the backcountry. Their deaths shocked the valley and became the final spark that united the settlers in retaliation.
Within days, a large posse was organized. Men from San Bernardino, Hesperia, and the mountain ranches gathered in Summit Valley, buried the dead, and set out to track the Indian band responsible. Their pursuit carried them northward through the mountain ridges and into the country around Rabbit Lake and Chimney Rock, where the final confrontation would soon take place.
The Pursuit and Battle at Chimney Rock (Winter 1867)
After the deaths of Parrish and Pratt, settlers and ranch hands across Summit Valley and the foothill country gathered to form a large posse. Around forty men took part, armed with rifles and revolvers, determined to track down the Indians believed responsible for the attacks at Las Flores Ranch and Burnt Mill Creek.
The trail led north through the timber and granite ridges of the San Bernardino Mountains. For several days, the Indian band held the high ground, watching from the ridgelines above the valley. They moved cautiously through the rugged terrain, following old paths toward the upper basin near Rabbit Lake.
From there, the group descended through the rocky terrain toward Chimney Rock, an isolated sandstone formation overlooking what is now Lucerne Valley. On the far side of the ridge, near Rabbit Springs, lay their village, a seasonal camp used for gathering food and trading with other desert groups.
As the posse closed in, the Indians made their stand among the boulders and ledges at Chimney Rock. A running fight broke out that lasted several hours. The settlers fired from cover while the Indians answered from higher ground with muskets and arrows. When the shooting stopped, between thirty and forty Indians lay dead, and the survivors fled eastward toward the desert.
The battle — fought in February 1867 — marked the end of large-scale Indian resistance in the San Bernardino Mountains. The settlers soon returned to Summit Valley, and word spread quickly through San Bernardino that “the Indian war was over.”
Aftermath and Legacy (After February 1867)
When the fighting ended at Chimney Rock, the mountains fell quiet again. The surviving Indians slipped away toward Rabbit Springs and the upper Mojave River, while the settlers gathered their wounded and buried the dead. Many of the Indian casualties were left on the field, and for years, travelers reported finding scattered bones among the rocks.
The posse returned to San Bernardino, where their action was hailed as the end of Indian trouble in the mountains. Local newspapers described the engagement as a victory that brought peace to the frontier, though for the surviving Serrano and Chemehuevi families, it was remembered as a deep loss. Entire families were wiped out, and those who remained moved away to the lower desert and to reservations at Morongo and San Manuel.
In the years that followed, Las Flores Ranch became a central stop for freighters and cattlemen moving between San Bernardino and the desert. The surrounding country was filled with new homesteads, and the Indian villages in the upper valleys disappeared. Only the stone outcrops and dry washes kept their memory.
A century later, in 1967, the State of California designated Chimney Rock as Historical Landmark No. 737, recognizing it as the site of the last major Indian–settler conflict in the San Bernardino Mountains. The monument still stands above Lucerne Valley, a reminder of a hard and tragic passage in the region’s history.
Memory and Historical Recognition (Late 19th Century–Present)
For years after the Battle at Chimney Rock, the story of the fight was passed down in fragments — part caution, part justification, and part fading memory. Early settlers spoke of it as a final act that “secured the mountains,” while Indian descendants told of families lost and villages erased. By the 1880s, as ranching and logging expanded, the details of who fought and why began to blur, preserved mostly in oral tradition and a few scattered newspaper mentions.
Interest in the subject revived in the mid-20th century when local historians, including Burr Belden and members of the San Bernardino County Museum Association, began gathering surviving accounts. These efforts led to the site’s formal recognition in 1967, 100 years after the battle. The Lucerne Valley Historical Society, in collaboration with the California Office of Historic Preservation, placed a marker on the flat area below the rock outcrop.
Since then, Chimney Rock has stood as a place of reflection rather than triumph — a reminder of how fear, misunderstanding, and vengeance shaped the San Bernardino frontier. Modern researchers and descendants of both settlers and Native families continue to revisit the record, trying to piece together a fuller picture of what happened along the old trails that ran from Summit Valley to Rabbit Springs.
The story of Chimney Rock remains not only a record of conflict but also a measure of change — from an era of violence and dispossession to one of remembrance and the slow work of understanding.
The Last Troubles and Santos Manuel’s Leadership (Late 1860s–1870s)
Even after the Battle at Chimney Rock, hardship did not end for the remaining Indian families in the San Bernardino Mountains. Scattered and grieving, small groups of Serrano and Chemehuevi people tried to return to their traditional camps along the creeks and canyons above Summit Valley. Settlers, however, now claimed most of the water and grazing lands. Sporadic raids and reprisals continued for several years, and the surviving Indian families lived in constant fear of being hunted down or driven away again.
By the early 1870s, leadership among the scattered mountain Serrano had passed to a man named Santos Manuel. Realizing that his people could not endure another winter of pursuit and hunger in the high country, he gathered the remaining families and led them down from the mountains into the valley below. They settled near the foothills north of San Bernardino, in a place that came to be called Politana, and later near Highland, where they would form the heart of the present-day San Manuel Band of Mission Indians.
Santos Manuel’s decision saved what remained of his people. Though stripped of their old homelands around Rabbit Springs, Summit Valley, and Las Flores, they survived as a community and carried their history forward. His leadership brought an end to years of conflict that began with the tragedies at Las Flores Ranch and Burnt Mill Creek — closing one of the most turbulent chapters in the story of the San Bernardino Mountains.
