NAME AND LOCATION OF CLOSEST CLIMATE STATION (latitude, longitude, and distance from borehole, km); PROVIDE SEPARATELY MEAN MONTHLY AIR TEMPERATURES AND SNOW DEPTH AS AVAILABLE

C4 bottom (65º10’26”N, 147º31’02W) about 800m upstream. 

Depth:30 m
Drilling Angle:90 °
Drilling Method:6” auger with 340 lb. Split spoon
Date Drilled:01. Mar 1999
Type:offroad vehicle
Distance From Road:1000 m
Slope:12 °
Aspect:350.6 °
Permafrost Thickness:>10 m
Permafrost Zone:Discontinuous
Vegetation:The vegetation consists of open black spruce forest and with 30 cm organic mat of feather mosses and sphagnum.
Landform:The site is base of the east facing slope on the ridge. Stream icing (aufeis) developed ca. 50m east of the drill site. There are wild fires at 1920s and 1999.
Lithology:There is fresh bedrock (Schist) at 6m below surface. Upper 3m is ice rich silt and gravel layer. Weathering bedrock layer was 3-6m.
Morphology:Valley, about 75m from stream (little poker creek)
