AbstractThe Chu Chua Creek (west half) map area is a gently rolling to rugged upland 900 to 1700 m in elevation. The topography is controlled by the underlying bedrock. Most of the area is underlain by Mesozoic batholiths with some Paleozoic volcanic and metamorphic rocks and limestone underlying the southern part, east Bonaparte Lake. Tertiary volcanic rocks also outcrop along the northwest margin of the map area and a small area about 4 km east of Bonaparte Lake. Many of the upland areas have been glacially streamlined during the last glaciation by a dominant ice flow from the northwest by the Cordilleran Ice Sheet. Glacial till covers most of the area and ranges from several metres thick, in valley bottoms, to thin discontinuous veneer over local uplands. Moraines and the orientation of meltwater channels indicate that deglaciation progressed across the map area to the northwest.
