View images of photographer Ansel Adams, biologist George Wright, John Muir and Teddy Roosevelt, as well as tourists and park vistas taken at Yosemite National Park. Yosemite is located in Northern California. The area was home to the Ahwaneechee Indians for thousands of years before white men arrived. Beginning in the mid-1800s, Yosemite became a tourist destination. Visitors were drawn to the region’s awe-inspiring landscape, which includes cliffs, glaciers, waterfalls, wilderness, and giant, ancient sequoia trees that stretch more than 200 feet into the air. The area was declared a National Park in 1890, through the efforts of conservationists like John Muir.
