Elevation range 186m. Bedrock symbols- Qs Detrital deposits, Qh Hot-spring deposits, Qhi Cemented ice-contact deposits localized by hot springs, Qhe Hydrothermal-explosion deposits. Transparent pink area is mapped as hydrothermal. Surficial symbols- fa fine-grained humic alluvium, sg stream gravel, si siliceous sinter, ds diatomaceous silt, psg outwash and stream gravel, phe hydrothermal-explosion deposit, pkgs gravelly sand, bksg sandy kame gravel, bkc cemented kame gravel. p = Pinedale age, b = Bull Lake age.
