Yosemite’s remarkable rock formations are among the park’s most recognizable features. On this guided weekend adventure, explore some of those 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!

  • Introductory evening meeting at Parsons Memorial Lodge on August 23, starting at 6 pm. In addition, two day hikes in Tuolumne Meadows (Saturday, August 24, at 8 am, through Sunday, August 25, until about 3 pm).
  • Park entry (as needed).
  • Camping included, if needed; limited sites are shared among all the participants (arriving August 23 and departing August 26) at Tuolumne Campground.
