Cape Halkett, Beaufort Sea, Alaska

Shoreline is crumbling into the water, and the land itself is interlocking polygons with brackish water in the centers.

Detailed Description

This photograph shows ice-wedge polygons and an eroding shoreline at Cape Halkett on the Beaufort Sea coast of 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.
