Hi All. It appears that this is not the first time Mount Rainier has had outburst floods. Take Care…Don in creepy town

The smallest, but most frequent, debris flows at Mount Rainier begin as glacial outburst floods, also called by the Icelandic term "j”kulhlaup" (pronounced "yo-kul-h-loip"). Outburst floods at Mount Rainier form from sudden release of water stored at the base of glaciers or within the glacier ice. Outburst floods have been recorded from four glaciers on Mount Rainier: the Nisqually, Kautz, South Tahoma, and Winthrop glaciers. From 1986 through 1992, South Tahoma Glacier released a total of 15 outburst floods, including at least one every year. These outburst floods from South Tahoma Glacier occurred during periods of unusually hot or rainy weather in summer or early autumn, and were apparently caused by rapid input of meltwater or rainwater to the base of the glacier. The exact timing of such outburst floods is unpredictable, however.
