Tribune staff report

The community is welcome to Lake Tahoe Community College on Friday at 7 p.m. in the Duke Theatre for a free slideshow and lecture on the geology of the Lake Tahoe Basin. In “The Geology of Tahoe: A Story of Earthquakes, Glaciers and Volcanism,” LTCC Earth Science instructor Scott Valentine will explain how a number of sometimes violent forces transformed the Basin and Lake Tahoe over the centuries.

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!”

This free event is sponsored by the LTCC Library. For more information, contact Scott Valentine at (530) 541-4660 ext. 313, or send an email to
