We thank Pathfinder Aviation for exceptional work in difficult circumstances, and the people of Whittier for their kindness and generosity. We greatly appreciate the Chugach Alaska Native Corporation and the U.S. Forest Service for their helpfulness and access to their lands during this study. Gordon Burton was of great help in allowing us access to the Whittier tunnel, which we were, unfortunately, unable to utilize. This work was funded in part by the 2012 U.S. Geological Survey National Cooperative Geologic Mapping Program, award number G12AS00007. Geologic map conversion to the GeMS standard was funded by the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G21AC10706, 2022, and the State of Alaska General Fund.

The city of Whittier, Alaska (pop. ~250), is one of only two all-weather, ice-free ports that serve the Alaska mainland via both railroad and road access. The city lies about 100 km by road southeast of Anchorage near the head of Passage Canal, a deep fjord in western Prince William Sound. The hazards assessment is in support of informed community planning, mitigation, and emergency response in and around this high-risk community and its associated critical infrastructure.
