The eastern Klamath Mountains flank I-5 between Yreka and Redding. Rocks exposed in the Eastern Klamath terrane record more than 300 million years of Earth’s history.

Since being added to North America, the Eastern Klamath terrane has been eroded, uplifted, and eroded again. During the past 5 million years glaciers and streams have carved the steep canyons that now dissect the region. This makes it susceptible to landslides and flooding.

It has also produced a wealth of gold and other mineral deposits whose extraction, sadly, has left a legacy of environmental damage.

Bill Hirt, Emeritus geology instructor at the College of the Siskiyous, will be exploring the fascinating intricacies of our surroundings in his presentation: Geology of the Klamath Range.

Presented in partnership with Siskiyou Land Trust
