High-Resolution Permafrost Maps for Western Alaska

Map of permafrost presence and locations of elevation extremes.

High-resolution elevation maps, based on LiDAR, were used to model the distribution of permafrost across the Y-K Delta of Alaska. The map insets show detail for areas of relative high elevation (left) and low elevation (right).

Scientists with NASA's ABoVE field campaign modeled the distribution of permafrost across the Yukon-Kuskokwim Delta of Alaska.
