• GENERAL INFORMATION: A wide variety of rocks, minerals, and semi-precious gemstones is available for collecting on 16 million acres of lands managed by the U.S. Bureau of Land Management (BLM) in Oregon and Washington. Most BLM lands are open to rock collecting, and some areas, such as the Glass Buttes obsidian area in our Prineville District and a public sunstone area in our Lakeview District, have been specifically set aside for this purpose. Collectors should note that there are some restrictions and a BLM permit may be required, depending on the amount of material you collect, how you collect it, where or when you collect, and whether the material will be used commercially. The following information is provided for the public to be used as a general guide for collecting on BLM lands in Oregon and Washington.
