Inventory of Rock Glaciers along the Ghunsa Valley, Kanchanjunga Himal, Eastern Nepal

Summary

This dataset provides information on a number of Nepali rock glaciers distributed above 4250 m ASL along the Ghunsa valley and the Kanchanjunga glacier (originating from the summit of Mt. Kanchanjunga, 8586 m ASL). The rock glaciers were identified on the basis of air photo analysis and were visited in October and November 1999. The longitude, latitude, and elevation of each rock glacier are given. Geographic coordinates were determined using a 1:50,000 topographic map of Nepal. Two categories of rock glaciers are described: glacier-derived and talus-derived rock glaciers. The internal structure of two rock glaciers (KR4 and KR23) were investigated by DC resistivity imaging. Data are available via ftp.
