An Iconic Landscape

In the heart of California’s Sierra Nevada mountain range, Yosemite National Park is home to one of the world’s most striking and beloved landscapes. Towering granite domes, gushing waterfalls, and diverse forest and meadow habitats provide the perfect setting for endless exploration and exciting, hands-on environmental science research. This summer, you can avoid the crowds and see a side of Yosemite National Park that many will never encounter.
