Hope you and your friend have permission to be there, looks very much like a field where i shoot, and i am the only one with permission to be there LOL.
its just that the top of the stone dyke looks very familiar, as i have stopped there loads of times and shot foxes in the field where your mate is, now i know why i havent seen any for a while in that field, hope you managed to get him out or he will be stuck in there until around mid may... HA HA HA
Outstanding powers of observation....I am impressed. Didn't realise you needed written permission to jump into some snow though lo
