Shifting shorelines at Lake Tahoe caused by ancient lava dams

Shifting shorelines at Lake Tahoe caused by ancient lava dams Pleistocene basaltic lavas form a small volcanic field that was erupted from seven vents in the northwestern Lake Tahoe basin. Most of these lavas were erupted above the water and produced lava flows that dammed the lake outlet and flowed into an early Lake Tahoe. The resulting steam explosions produced deltas composed of fragmental deposits as well as pillow lavas. http://ift.tt/eA8V8J
