Program Overview: Yosemite Valley’s remarkable rock formations are among the park’s most recognizable features. On this guided adventure, explore the ancient forces that created icons like Half Dome, Glacier Point, El Capitan, and much more with National Park Service Geologist Dr. Greg Stock. He’ll give you the inside story of Yosemite’s peaks, domes, and cliffs — including how glaciation sculpted Yosemite Valley’s massive cliffs and how rockfalls continue to shape them. Bring your scientific curiosity and rock-related questions!
