Natural history
[edit]The Searles Lake is an endorheic dry lake formed by the evaporation of lakes during the late Quaternary period. It contains rich deposits of chemicals, including borax and rock salt.[4]
Searles Valley is known for its isolation and desolation,[5] as well as the nearby Trona Pinnacles a few miles to the south. The Trona Pinnacles are an unusual landscape of more than 500 tufa spires, some as high as 140 feet, rising from the bed of the Searles Lake basin.
The name Trona is derived from the mineral trona, abundant in the lake. The local school plays on a dirt football field because the high level of salt kills grass.
2019 earthquakes
[edit]In July 2019, Searles Valley was impacted by a series of earthquakes, the principal events (with magnitudes of 6.4, 5.4, and 7.1 Mw) occurring from 12 to 18 kilometers west on the Naval Air Weapons Station China Lake.[6] The earthquake series started at 10:02 AM on July 4 with a Mw 4.0 earthquake 4 kilometers southwest of Searles Valley. At 10:33 AM a second and much stronger earthquake struck – a 6.4 magnitude quake 12 kilometers southwest of Searles Valley.[7] The earthquake was felt throughout the area and Southern California, including Los Angeles, and in Nevada, including Las Vegas. The earthquake was 10.5 kilometers deep.[8] Over 100 aftershocks impacted Searles Valley and nearby Ridgecrest, California.[citation needed] This second quake was followed by an even larger 7.1 magnitude quake, subsequently designated the main quake in the series, on July 5, 2019, at approximately 8:18 PM. The valley experienced a 3.9 magnitude quake on July 22, 2019.
