Sunstone Collection Area

Know Before You Go: The boundaries of the Oregon Sunstone Public Collection Area are marked by orange plastic posts that say ‘Oregon Sunstone Public Collection Area,’ and corners are marked with large Bureau of Land Management triangles on wooden posts. There are many private mining claims surrounding the public collection area and several within it. Collecting Sunstones from a private claim without permission is not allowed and may result in legal penalties. Please take the time to know where you are before collecting. Due to the isolated location, rock hounds visiting the collection area should be well prepared. The only facilities available at the site are a pit toilet, picnic tables, and a shade structure. You are welcome to camp anywhere within the Oregon Sunstone Public Collection Area. Point of Interest: Sunstones are feldspar crystals that formed in lava. Thirteen to fourteen million years ago, a volcano in Steens Mountain erupted, pouring out massive amounts of lava. The lava flow was subsequently covered by a vast lake and remained underwater for thousands of years. As the lake gradually dried up, the exposure to weather caused the lava to decompose and reveal loose sunstones.
