Interred within a fenced enclosure are 16 people killed when one of the largest earthquakes ever to hit California rocked Lone Pine at 2:35 am on March 26, 1872. It awakened residents hundreds of miles away in all directions. Damage was so widespread, adobe buildings in Red Bluff collapsed, 400 miles north of the quake. John Muir who was living in Yosemite at the time was awakened and took the opportunity to study the changes in the land and rock formations within the valley immediately afterwards.  It was also reported at the time that people in Sacramento, 300 miles away, felt the impact of the earthquake and ran in panic to the streets. Residents of San Diego also reported an earth shaking experience. Although there were no official recording devices at the time, the quake was estimated to be 7.6 to 8.0 magnitude on the Richter Scale. The quake was thought to be similar in size to the San Francisco quake of 1906. Two faults moved simultaneously. The vertical fault moved roughly 15-20 feet, while the right lateral fault moved roughly 35-40 feet. The twin faults run along the base of the Sierra Nevada and Inyo Mountains, according to USGS and Wikipedia. Most buildings in Lone Pine were made from adobe brick and crumbled to the ground. Twenty-seven of the approximately 250-300 residents of Lone Pine were killed, according to several different sources.  The adobe buildings located on Camp Independence also fell and the Camp was subsequently closed. The historical marker is located 200 feet west of Highway 395 (P.M. 58.7) about a mile north of the current city of Lone Pine.
