Emigration Over South Pass

“’From 1812 to 1848 travel up the Platte was only minimal to moderate, historian Merrill J. Mattes observed, ‘with a grand total of around 5,000 to Salt Lake, 10,000 to Oregon, and 2,000 to California.’ Between 1849 and 1852, about 120,000 people—mostly men—would flock to the gold fields over the California Trail, while some 35,000 more men, women, and children would cross South Pass on their way to Oregon or the Great Basin.”
