Description

This is a large section of the Quelccaya Ice Cap margin. A couple decades ago, ice covered virtually the entire scene, which is larger than it appears here (135° FOV). This ice-dammed lake could drain at any time, if a delicate balance is upset between hydrostatic pressure and the restraining capacity of the glacier - which is gradually decreasing as the ice thins. Drainage is probably most likely to occur during the relatively warmer, summer wet season (Dec-March) when most melting occurs. Ice cover is typical during July, making swimming difficult.
