Mysterious Holes In Russia

I have no idea why there are some deep holes appear in dense forest where you can’t get on the car or truck to bring any device to drill the ground. People go down one of the holes but they found nothing. What could they be?

Duuuuuuh! These are OBVIOUSLY holes created by a mother ship from space through which are seeded alien eggs inside an ancient civilisation pyramidal structure for the purpose of war games between rastafarai aliens and the other type there that springs out of one’s thoracic cage….
Mining airshafts…roll on the floor laughing my sweaty nuck sack off….well I’ve heard every thing. Quite the imagination there, eh?

When a volcano hits a coconut palm filled island the lava and hot ash sweep over the land. Trees like coconut palms are buried along with their root system. When the fire goes out and time passes people find these mysterious holes in the earth. They go down into the deep and they are not that wide but very round. These are coconut palms or other kind of trees which were burned to ashes but not until the lava and ash had moved on. Time eroded out the covering to these holes leaving us with a mystery.

i absolutelly agree with jon doe. definately giant worm holes lol.
do u know how old they are? or how deep?
it could just be that there was too much pressure deeper down in the earth and it somehow created a sort of pull towards the centre, pulling down everything it could ( and then it eventually reached the surface…) just an idea…
