Lake Tahoe’s active geological past explored in free LTCC lecture

Scott Valentine will explore Lake Tahoe's geological past in a free lecture and slideshow on Friday night. Valentine, an Earth Science instructor at Lake Tahoe Community College, will explain how a number of sometimes violent forces transformed the Basin and Lake Tahoe over the centuries.

"The Geology of Tahoe: A Story of Earthquakes, Glaciers and Volcanism" will be presented at the college's Duke Theater on October 10 at 7 p.m.

The weather, erosion, and plate tectonics that combined to forge and shape Lake Tahoe and the mountains that surround it were considerable, according to Valentine. “We’re talking lower crustal magmatic injections, 600 year droughts, underwater landslides, and catastrophic ice dam failures. Come learn the real story behind the creation of America’s year-round playground, and why you should invest in a waterproof bunker!”
