   Aerial image of a forming thermokarst lake in western #Alaska. Ice wedges in the ground are melting, the ground is sinking/subsiding and water is ponding in the newly formed depressions. This process will likely continue and accelerate and eventually form a #lake
   The image is around 370m wide and taken from about 1000m altitude in one of our flight campaigns in 2021.
