The Point Reyes Peninsula has long baffled geologists. Why should the rocks of this craggy coast match rocks in the Tehachapi Mountains more than 310 miles to the south? The answer lies in plate tectonics and the continual motion of the Earth’s crust.
Geologically, Point Reyes National Seashore is a park on the move. The eastern border of the park parallels the San Andreas Fault, which is the current tectonic plate boundary separating the Pacific Plate from the North American Plate.
The remaining sides of the peninsula are intermittently edged by beaches, sea cliffs, and intertidal zones cascading into the Pacific Ocean. Encircled by this rich assemblage is a mosaic of ecosystems arranged by factors such as geologic foundation, climate, and exposure. While there are dozens of ways to classify and name the exact type of ecosystem, the broadest and closest category places Point Reyes National Seashore into a Mediterranean Ecosystem.National Parks Service
This can be a forbidding place, a world foreign to outsiders. Medicine Lake is a shield volcano that’s been active for 500,000 years. Its eruptions, from surface vents have been gentle rather than explosive. The eruptions resulted in a low, gently sloping shield-like profile.
The Modoc and their ancestors called Lava Beds home for over 10,000 years. Following the rhythm of nature, they roamed this land freely until they were forcibly moved to the Klamath Reservation in nearby Oregon.National Parks Service
