From the plaque:
In this area, several groups
of midwestern emigrants, who had escaped from hazards and
privations in Death Valley in 1849 sought to secure water
from Searles Lake. They turned northward and westward
in despair when they discovered its salty nature, and
with great difficulty crossed the Argus and other mountains
to reach settlements of Central and Southern California.
