Stranded ice following an outburst flood, or jokulhlaup, occurs when ice dammed water bodies drain suddenly, usually under the glaciers. These floods are commonly much larger than storm induced floods and consequently are more devastating in their downstream effects.

Un-named valley north of the Bremner Glacier. Wrangell St. Elias National Park. (4x5inch film)
Stranded ice along the western margin of the Kennicott Glacier following the release of impounded meltwater beneath the glacier. The resulting floods are commonly much larger than storm induced floods and consequently are more devastating in their downstream effects. Hidden Creek Lake, Wrangell St. Elias National Park.
