Abstract:
The map encloses a 20 km^2 area surrounding Toolik Lake that stretches from the Dalton Highway on the east to Jade Mountain on the west. It includes the Toolik 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 Toollik Lake. The area contains surfaces with irregular topography that were glaciated during the Late Pleistocene. Toolik Lake area map of surficial geology clipped so that it could be displayed as a rectangle within the map frame, eliminating the diagonal borders.
Surficial geology affects vegetation patterns and disturbance recovery rates. Surficial geology was grouped into the following classes for map display:
Glacial till deposit: Glacial till in the region was deposited during the Sagavanirktok and Itkillik glaciations (mid and late Pleistocene). Till surfaces are generally rocky and gently undulating with blockfields, and nonsorted circles. Till on most surfaces has been covered by fine-grained colluvium that has been transported from upslope.
Glaciofluvial deposit: Outwash deposited by meltwaters from the Pleistocene glaciers. Glaciofluvial deposits cover large areas marginal to many modern floodplains. Outwash deposits have irregular, rocky microrelief with a wide variety of landforms including kames, kame terraces, and flat terraces with high-centered polygons.
Other alluvial deposits: Stream deposits occur on modern and ancient floodplains, watertracks, and alluvial fans.
Colluvial deposit: Hillslope deposits whose origin is due primarily to downslope movement of material under the force of gravity, but often also in association with forces due to water movement. Colluvial materials often cover other deposits and bedrock.
Bedrock: Includes all exposed bedrock and weathered bedrock deposits. Most bedrock is a mixture of sandstone and conglomerate (Kanyute Formation).
Organic deposit: Organic deposits greater than 50 cm deep occur in colluvial basins and in some areas with wide watertracks.
Laucstrine deposit: Lake sediments occur in association with drained glacial lakes such as Galbraith Lake and along the Sagavanirktok River, and a few much smaller drained glacial kettles and ponds.
Water: Includes lakes, ponds and rivers
Disturbed areas: Includes all anthropogenic disturbances, such as gravel pads, gravel mines, and airstrips
