You seem to really be able to get out into the back country a lot to get these shots. Do you combine this with backpacking and camping trips, or are these mostly day hikes? 
sorry dave, missed this.  thanks for your kind words.   
I usually do "day stuff."  I also do a lot of camping in my truck, and "hide."  I dont camp in the campgrounds but I do camp. . .   
As for long term "backcountry"  It's too much to take 40 lbs of phototraphy gear AND camping gear on your back.  Also, if i'm in glacier park, I need a backcounty pass (to spend the night, also you have to use approved sites), i hate that and therefore I dont play that game. . . 
I leave VERY early, and return VERY late, but have been known to weather a night here and there if it's not too cold.  
Did you read my description of how I got these shots? 
I do like the idea of being gone on a backcountry safri but cant afford to hire the stock and therefore I stick to my own feet for travel.
