home / agates worldwide / Northamerica / USA / Idaho / Brownlee Reservoir, Snake River

“ ... These Idaho agates are called Snake River agates. They are found in the Columbia River Basalt Group. This basalt group is rather large and is found in Oregon too. Agates are found in various locations in this formation, however, the vast majority of these agates are gray and white... The location for these specimen here is above the Brownlee Reservoir of the Snake River. It is aprox. 50 miles north of Weiser, Idaho. I understand that folks pick agate here but have never seen or heard of these agate mentioned in the agate books ...”
