Lake Bonney

Description: 

Lake Bonney occupies a glacially scoured bedrock basin in Taylor Valley. It is located at the head of the valley and is perennially ice-covered. The lake has two basins (lobes) connected by a narrow, shallow channel. There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring). The lake is bordered to the north by the Asgard Range and to the south by the Kukri Hills. Mountain and cirque glaciers occupy hanging valleys between these peaks and supply meltwater intermittently to the lake during warmer periods in summer. The largest source of meltwater, however, is from the Taylor Glacier, which extends from the polar ice-cap and terminates in the western end of the west lobe of Lake Bonney.
