The central map of the Geoscape poster shows the distribution of the various types of bedrock and unconsolidated sediments in the region.
Material characteristics relevant to forestry, the environment, fisheries, and land-use planning are summarized in the map legend.
The surrounding thematic maps focus on the particular geological issues: controls on stream productivity, the natural enrichment of mercury and molybdenum in the region, and the vulnerability of aquifers.
Geoscape Fort Fraser shows geology of the northern Nechako Plateau area of central British Columbia.
Physiography is the surface form of the Earth. The Fort Fraser map area above includes flat and rolling lowlands, rolling uplands, and low-lying mountains. The mountains increase elevation to the north. Uplands of glacial till and glacial river sediment flank the mountains. Lowlands are areas of glacial lake sediment cut by modern rivers and creeks.
