Yosemite is a treasure among America's National parks. towering peaks, glacially sculpted valleys, alpine meadows, and spectaular waterfalls are just a part of the land surveyed by John Muir and others in the late 1800s.
Tuolumne Meadows, El Capitan, Glacier Point, Hetch Hetchy, Half Dome, Yosemite Valley and Bridalveil Falls give us awe-inspiring views and memories. These spectacularly beautiful and unusual landforms, along with thier flora and fuana, are just part of the Yosemite story.
What geologic processes have converged to make this land a jewel of North America? Did you know oceans and volcanoes once occupied the entire park area, long before steep canyon walls defined yosemite Valley? Where are the remnants of those oceans and volcanoes? Some important geologic features can only be seen on the highest peaks of the park. What other storeis do the rocks tell us? What geologic activities continue today?
Join local geologis Tim Elam as he presents a photographic overview of the geology of California's first National Park.
The presentation is informal, questions and discussion are encouraged. no geologic background is necessary to enjoy the event.
