Remarkable rock formations, including sheer cliffs, polished domes and soaring peaks, are among Yosemite’s most recognizable features — this unique landscape is one of the reasons the park is designated as a UNESCO World Heritage Site. 

On this guided weekend adventure, you’ll explore some of Yosemite’s famous features in the Tuolumne Meadows area with a park geology expert. During two day hikes, you’ll get the inside (and ancient) story of Yosemite’s peaks, domes and cliffs. Learn how glaciation has shaped the Sierra landscape, from the jagged nunataks that jutted out above the ice to the erratic boulders left behind when the glaciers melted. Bring your scientific curiosity and rock-related questions!

For a preview of the weekend, watch Yosemite Nature Notes: Granite, and read our blog post Glaciers on Granite.
