Southward the altitude falls, Death valley and Coahuila valley being in part below the level of the sea.
from the lake is Death Valley (including Lost or Mesquite Valley) - the name a reminder of the fate of a party of " forty-niners " who perished here, by thirst or by starvation and exposure.
At any rate it may be said that generally speaking the maximum, minimum and mean temperatures of points of approximately equal altitude are respectively but slightly different in northern or southern California.2 Death Valley surpasses for combined heat and aridity any meteorological stations on earth where regular observations are taken, although for extremes of heat it is exceeded by places in the Colorado desert.
More than nine-tenths of the borax product of the country comes from about Death Valley.
