Sam:
Antarctica
There are several timespace rips healing over near the cracked glacier. There is also a slight magical boundary around the glacier itself, extending quite far downwards. It would seem that the glacier is not a natural part of this landscape, but was moved here from elsewhere by some magical force. Further down, there are two leylines crossing in the earth far below.
The only other magical points of interest are two small rapidly re-freezing puddles of water (which show traces of magic for some reason) and a human-shaped hole in a nearby snowbank, with a single set of footprints leading a few steps away before disappearing.
