It is located on the northern slope of Rock Creek Butte, the highest point in the Elkhorn Mountains range.

While the lake is located on a glacial cirque, it is part of the West Fork Rock Creek drainage basin.

[4] The glacier meltwater flowed northwest in the direction of the cirque and then veered northeast producing a confluence with the North Fork of Rock Creek.

The lake has several species of fish, including Bass, Bluegill, Crappie, and Sauger.
