Identification, classification, and distribution of retrogressive creeping slumps, Lac de Gras region, Northwest Territories / T.L. McWade ... [et al.].: M183-2/8197E-PDF
"The purpose of this Open File is to identify and map a locally common yet unclassified set of landforms first observed during summer 2015 fieldwork in continuous permafrost of the Lac de Gras region of Northwest Territories. Quantitative and qualitative data extracted from 152 landforms using aerial photographs and LiDAR data were used to describe and quantify the general form. The landforms exhibit a continuous depression situated several meters behind and parallel to a steep, curvilinear hillslopes, beneath which is a gentle footslope. The hillslopes appear to incise the margins of till blanket deposits, and the footslopes are covered with boulders. According to morphological characteristics, the mapped landforms were divided into three classes, interpreted as early, late, and final stages of an apparent time-transgressive landform evolution. Based on extracted morphological characteristics and field observations the landforms have been tentatively termed retrogressive creeping slumps"--Abstract, p. [1].
