"Cavansite Hill" as seen from the south

Owyhee Dam, Lake Owyhee State Park, Malheur Co., Oregon, USA

This is the south side of "Cavansite Hill." Note the change in the color of the rocks near the shadowed line in the outcrops. A fault zone containing calcite crystals occurs at the boundary between to two colored rocks. This may be the area where cavansite is said to have been found to the south of the road cut.

The famed type locality road cut

Owyhee Dam, Lake Owyhee State Park, Malheur Co., Oregon, USA

As best I can tell this is the road cut where cavansite was first found. It is cut by numerous small faults and calcite veins. Most of the veins are too small to see in this photo, although light colored surfaces on the rock in the right side of the outcrop are coated with vein calcite. No cavansite was observed here during a brief reconnaissance on June 14, 2010. This fault zone extends to the south over the crest of the hill under shallow cover and re-emerges on the south side of the hill as a more discrete single fault.
