Quaternary geology of the Zama City area, northwestern Alberta
Geologic studies in the Moody Creek (84M/02) map area were undertaken to map surficial geology, establish glacial history, and classify materials geotechnically. Surficial geology mapping was completed in 2006. The stratigraphy is represented by 6 units: glaciolacustrine; till; englacial/subglacial...
