Big Horn Beach

The topography of this area on the northern shore in the lower portion of the lake is formed primarily by a combination of massif granite cliffs, the lower slopes of having been exposed by the great Missoula Floods. On the southern shore of the lower lake is an opposing a mixture basalt in both columnar and vertical faced mounds. Both rock types in this area tend to be clean and stable, thus the climbing and bouldering is quite nice.
