I like that Clearing Firestar, here is my idea of hunting grounds.
http://farm3.static.flickr.com/2133/1779400193_20945640a4.jpgThe grass is tall so the wolves can sneak well towards the animals that they are hunting. Tree's can be used to hide the wolves as well, and the deer can dash into the trees.
And this is from Jetspear on the in the old pack, i thought that it was good and shouldn't be put to waste.
The meeting spot,

This could be the den?
The tree over top stops water from entering the den because it sucks up the water. In Summer and Spring the Den is mostly hidden from view because the leaves of the tree hide it, and plus it is a pretty large den.

http://www.geog.ucsb.edu/~ted/Alaska/050828_139-lake-near-AK-Yukon-border.jpgThe territory could end at this lake which will be well marked and such by the pack, and plus it is water that could easily become a great place to lie down by and drink from while keeping an eye out for trespassers.
This could be another end,
http://www.geog.ucsb.edu/~ted/Alaska/050828_093-near-Denali-road.jpgThe land flattens out a bit with a small stream running through it, then the tree's come and the mountains. You could see the end for a while and be able to notice other wolves easily.
And the last border,

Hope that I helped with the Areas!
