Death Valley '49ers The Death Valley '49ers were a group of pioneers from the Eastern United States that endured a long and difficult journey during the late 1840s California Gold Rush to prospect in the Sutter's Fort area of the Central Valley and Sierra Nevada in California. Their route from Utah went through the Great Basin Desert in Nevada, and Death Valley and the Mojave Desert in Southern California, in attempting to reach the Gold Country. On January 24, 1848, James
Death Valley heated, it begins to rise, moving up past steep, high mountain ranges, which then cools slightly, sinking back down towards the valley more compressed. This air is then reheated by the sun to a higher temperature, moving up the mountain again, whereby the air moves up and down in a circular motion in cycles, similar to how a convection oven works. This heated air increases ground temperature markedly, forming the hot wind currents that are trapped by atmospheric pressure and mountains, thus stays mostly within the valley. Such hot wind currents contribute to perpetual drought-like conditions in Death Valley and
