Yosemite's Valleys

Yosemite National Park in California is renowned for its stunning landscape, shaped by glacial activity over millions of years. Originally covered with V-shaped valleys, glaciers transformed them into U-shaped valleys, creating dramatic cliffs like El Capitan, a challenging climb for enthusiasts. The park's smooth rock faces and scattered boulders are evidence of glacial erosion and plucking. Yosemite's breathtaking scenery, including hanging valleys and waterfalls, showcases the powerful impact of ice on the environment.
