New photos show inside mysterious hole on Yamal Peninsula
The mysterious crater on the Yamal Peninsula, discovered by helicopter last week, is not as wide as original aerial estimates suggested. It is now thought to be about 30 meters wide, in contrast to original estimates of up to 100 meters. However, the crater is now known to be up to about 70 meters deep, and it’s seen to have an icy lake at its bottom, with water cascading down its eroding permafrost walls.
A Russian science team has now returned from exploring it, but there are still no easy answers as to what caused it. Their next step, they say, is to use Russian satellite pictures to fix the moment when the crater suddenly formed.
They know it was not there two years ago.
Bottom line: Scientists are back from a first exploration of the strange crater on the Yamal Peninsula in northern Siberia. Curiouser and curiouser.
