I do it all the time for predator hunting in our National Forest.
On my last elk trip I miscalculated(read in screwed up) and got altitude sickness real bad. Luckily I had pre-researched an alternate area at 9K and was able to keep hunting. Ended up finding a honey hole but ran out of time in the end and came home empty handed. I'd be headed back to it this year, but I missed out on my tag for Unit54. Right now I'm paper scouting for 55 and have the responsibility of finding a spot good enough to put my brother and his hunting buddy onto some bulls. All from over 1,000 miles away with no on ground scouting before hand. It can be done, but it requires much luck and a little help from guys on the forums (like this one) who live localy.
