I've been working in Sakhalin, island Russian federation on and off for the last six years.
The weather can get unbelievably cold and it's snow for about five months of the year. It started snowing heavy toady and I got to looking back through some old pics
Here's A Tucker snow cat. This is used for cross country crossing in the winter. It's also a rescue rig.
Here's an idea of the amount of snow fall.
The coldest temperature I seen recorded here is -58.
I'll post some more tomorrow. It's steak night tonight in the camp and I got to make sure I get in front of the locals.
