A Sunset at Smith Rock

$99.00$360.00

The geology of Smith Rocks is volcanic. It is made up of layers of recent basalt flows overlaying older Clarno ash and tuff formations. Approximately 30 million years ago, a large caldera was formed when overlying rock collapsed into an underground lava chamber. This created a huge amount of rock and ash debris that filled the caldera. That material solidified into rock, becoming Smith Rock tuff. Rhyolite flows intruded along faults in the Smith Rock Tuff. A half million years ago, basalt lava flows from nearby volcanoes covered the older tuff.
