The best reader-friendly book on Yosemite’s formation is “Geology Underfoot in Yosemite National Park.” It was co-written by Allen F. Glazner, Professor of Geological Sciences at the University of North Carolina and our own Ranger Greg Stock, the first-ever Park Geologist at Yosemite. The advances in technology such as LiDAR, high resolution photography, seismic monitoring, rock-fall runout simulations and cosmogenic dating are now part of the Park’s tools to study rockfalls.

Did you know that George Anderson met with the Yosemite Board of Commissioners and presented the idea of building a wooden staircase up the backside of Half Dome? They set aside $2,000 for the project. While nothing came of it, the Mariposa Gazette did report the news: “The stairway will be about 2,000 feet long, fastened by bolts in the rock on the side of the dome, in the most secure manner, and will be arranged with wings or arms extending all the way on each side, making it convenient and comfortable for visitors to rest and view the wonderful scenery below. The projector of this work expects to have it completed sometime the coming Fall, and ready for visitors next summer.”
Unrelated thought worth quoting: “As long as I live, I’ll hear waterfalls and birds and winds sing. I’ll interpret the rocks, learn the language of flood, storm, and the avalanche. I’ll acquaint myself with the glaciers and wild gardens, and get as near the heart of the world as I can.” – John Muir
