Abstract:
The surficial geomorphology map of the Upper Kaparuk River region covers 751-km^2 in the upper Kaparuk River watershed, including the Toolik Lake and the Imnavait Creek research areas, as well as portions of the Dalton Highway and Trans-Alaskan Pipeline from the northern end of Galbraith Lake to Slope Mountain.
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.
Organic deposit: Organic deposits greater than 50 cm deep occur in colluvial basins and in some areas with wide watertracks.
Lacustrine 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.
Eolian deposit: Windblown fine sand and silt associated with drained lakes and loess from rivers.
Bedrock: Includes all exposed bedrock and weathered bedrock deposits. Most bedrock is a mixture of sandstone and conglomerate (Kanyute Formation) (code 72), but areas of Lisburne limestone bedrock (code 71) occurs in the southeast portion of the map.
Water: Includes lakes, ponds and rivers.
Disturbed: Includes all anthropogenic disturbances, such as gravel pads, gravel mines, and airstrips.
Purpose:
