Figure 2. Geologic map of the study area, including locations of key mineral occurrences. Geology adapted from Sicard and
others (2017). Dashevsky and others (2003). Wilson and others (2015). and Illig (2015). Prospect locations adapted from
Alaska Resource Data File (U.S. Geological Survey, 2018), Degenhart (1978), and this study.
