The lake sits atop a lateral moraine on the side and end of Bartholf Glacier and drains into Mill Creek. It is named for Albert Bierstadt, a noted landscape artist, whose 1870s paintings of Longs Peak and Bierstadt Lake are among the Denver Art Museum's collection.

Geology and hydrology

Bierstadt Lake rests on a plateau on the Bierstadt Moraine, which is a "massive" moraine created by debris left from the receding Bartholf Glacier. The glacier, never more than 8 miles (13 km) long, "originated on the highest mountain in the park". Because it was a steep glacier, "its gouging action was vigorous". Glacial lobes at Glacier Gorge, Loch Vale, and Flattop Mountain joined and moved iced in Barthlolf Park. Debris trapped in the ice created the Bierstadt Moraine that lies between Glacier and Mill Creeks and is more than 1 mile (1.6 km) wide and is more than 900 feet (270 m) above the floor of Bartholf Park. The lake was formed when a dam was made from glacial debris deposits. Water from the lake drains into Mill Creek within the Mill Creek basin, which is a flat valley with a scenic meadow. Author Lisa Foster describes the long glacial ridge as "one of the most dramatic lateral moraines in the Rocky Mountain National Park". On the north side of the moraine is Hollowell Park and the Mill Creek Basin. The steep south side sits above Bear Creek Road.
