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
