Toolik Lake Area Surficial Geomorphology

Map of the Toolik Lake research area surficial geomorphology . The Toolik Lake area map is near the western boundary of the Upper Kuparuk River region map and encloses a 20-km² area surrounding Toolik Lake that stretches from the Dalton Highway on the east to Jade Mountain on the west. It includes the Toolik Lake Field Station, the old Toolik Lake pipeline construction camp gravel pad and airstrip on the northeast side of the lake, and the primary terrestrial research areas on the south, west and east sides of the lake, as well as several smaller research lakes in the immediate vicinity of Toolik Lake. The area contains surfaces with irregular topography that were glaciated during the Late Pleistocene.

The surfaces of the landscapes in the Toolik Lake area have been modified by a variety of geomorphological processes including alluviation (movement of material by water), colluviation (movement of material by gravity), and periglacial processes (freezing and permafrost-related phenomena). Common surficial geomorphological features within the mapped area include sorted and nonsorted circles (frost boils), turf hummocks, gelifluction lobes and terraces, water tracks, high-and low-centered ice-wedge polygons, wetland features and thermokarst features.The attribute table contains data for vegetation, surficial geomorphology, surficial geology, glacial geology, and water.
