Caribou Tracks Along Alaska's Coast

Detailed Description

This photograph shows caribou tracks on ice-wedge polygons near Garry Creek in Alaska. Coastal erosion along the Arctic coast is chronic, widespread and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats and nearby Native communities. To help address these concerns, the USGS is collecting information on past and present shoreline changes along the conterminous United States and parts of Alaska and Hawaii.
