Euro-Americans
Trappers, including Jedidiah Smith, and several military expeditions, one led by Captain John Fremont, traveled across Nevada in the early 1800's. Mail and pony express stations dotted the landscape by the 1850s. Immigrants on the way to California crossed the northern Great Basin on the California Trail.
Around 1855, the first Euro-American entered the area around Great Basin National Park to establish ranching. Discoveries of silver and gold in the region brought six mining operations to the South Snake Range. The largest one, Osceola, is on the west side of the range outside the park boundary. The Johnson Lake Mine, inside the park, operated well into the 20th century.
In the 1870's Absalom Lehman established a ranch near today's Lehman Creek, where he grew and raised food for local miners. Trees from his orchard still survive near the Lehman Caves Visitor Center. In 1885, he discovered the cave that now bears his name and devoted the rest of his life to guiding people through the natural wonder.
Ranching has been a significant part of the Great Basin's cultural heritage. For many years cattle grazed on the east side of the South Snake Range, even after the establishment of Great Basin National Park. Sheep still graze in the summer months on high elevation meadows on the west side of the park.
