home / agates worldwide / Northamerica / USA / Oregon / Burns, Secret Ridge (Harney Rim)

Around Burns several well-known places of discovery for thundereggs are situated. The Secret Ridge offers thundereggs of bluish - white color. The pattern is often a composition of common agate-banding together with “water-level-agate” (gravitional caused banding). The matrix is fine-grained up to aphanatic.


“ ...Burns – Secret Ridge: This thunderegg bed is located very near to the old Buchanan Ranch location. It is privately owned, but many of these eggs are found for sale at rock shops and on the internet. There are a few eggs from here that have wonderful and complex fortification banding rather than Uruguay or waterline banding. This bed is also known as “Harney Rim”...”
