摘要：

Measurements of subsurface movement and temperatures from a 17m bore hole in RGII a rock glacier overlooking Kluane Lake, Yukon Territory, suggest that it is becoming inactive. Present movement appears to be intermediate between a Newtonian viscous flow and one in which velocity decreases exponentially with depth. Between 1971 and 1976 the internal summer temperatures of all but 1.5m of the middle section of the bore hole rose to above freezing, and evidence of new thermokarstic development appeared. -from Authors
