Vast ice depression in Dålk Glacier, East Antarctica
In the afternoon of January 30, 2017, the wide depression in the western part of the Dålk Glacier, East Antarctica, was formed. By coincidence, aerial surveying was carried out in this area, so it is possible to assess the extent of this catastrophic phenomenon. Aerial photos were taken on January 2...
