Abstract: A rare observation of a slushflow that released on a low-angle slope was made on 16 May, 1992 in the West Karakol Valley, southern Kirgiz Range, Kirgizstan. The slushflow released on a short slope of 6° and traveled a distance of 140m over a slope with a mean angle of 3° with a mean channel width of about 4 m. Total volume of snow and slush transported by the slide was 224m3 with ah estimated mass of 208,000 kg. Estimated velocity of the the flow was 5ms-l. Meteorological conditions preceding the event were mixed weather with warm temperatures and both heavy cloud cover and clear skies. The day before the event rain fell for about 6 hours. Mixed rain and snow precipitation continued through the preceding night accompanied by steady high winds. The day of the release was hot with overcast skies and light rain. The snowpack was saturated to the surface at the time of the release with visible surface water flow.
