Replying to Exploring Off-Trail

The last couple of winters I have been getting into exploring off-trail at ski resorts and finding cool lines and powder stashes. I typically just cut into small gaps in trees where there are sometimes tracks and make my way down as well as I can. I'm always worried when I do this, though, because I feel like I'm going to run into a spot where it's impossible to get down because of cliffs or trees getting too thick. It's nearly impossible to get anyone to tell you about specific lines, which I totally get because the few tracks are part of what makes this kind of skiing appealing, but I don't know how else to find out about them without just blindly entering the woods in random places.
(I also mostly go alone which is probably not the best idea)

How do other people go about exploring the mountain outside of the marked trails?
