Serpentine Geology of the Klamath-Siskiyous

September 19 @ 8:00 am - 5:00 pm

$70

With its ultramafic rock uplifted from dense seafloors, rare mineral composition and unique landscapes, the Klamath- Siskiyou Mountain range could be viewed as a half-billion year-old geostar. This workshop will examine and illustrate why the Klamath-Siskiyous are so globally distinctive. Their knotted complexity is legendary: older rock slathered over younger, post-Jurassic rocks overlaid on Siletzia terrane. They have undergone monumental shifts: crustal-scale crashes, uplifts and rifts — everything but a crash between the continents. Our class will begin with an overview of how these mountains evolved, with geologic maps for reference. Then we’ll foray through the Illinois Valley and along the Smith River Canyon, stopping to study significant rock formations along the way. We’ll end our serpentine journey at the beach in Crescent City.
