I think this is mostly used by UK pilots, but someone might be able to help you. If you don't get any replies, try the US specific forum.
For some ideas, mabye get the "Out There....Flying" DVD of Backcountry strips in Utah, or contact the Backcountry Flying Association of Utah, they seem to be good at that sort of stuff. I don't have a link sorry, but a google would find them I'm sure!
Thanks,
