stupendous-manUnfortunately, there are no jump spots within 100 miles of Revelstoke, or really all of BC for that matter. Sounds like you're shit outta luck
Ive lived in revy for 13 out of 15 years of my life, theres tons of spots. ^
If your heading out to RMR then go out of bounds south (assuming you have avy gear) and hike up a little, theres a good roll over with a nice in run and a long landing. Theres alot of spots in south just don't go down further than the first cat road other wise your in for a long night. Or go out of bounds greally bowl (the one passed north bowl) and theres a place called "The Playground". its just out of bounds and theres a big landing that gets blown over with snow every night so you'll have a good landing any day. theres a big rock off to one side so you'll know it when you see it. also when your leaving hike out the way you came in, theres like 300 foot cliffs if you go down far enough.
Other than RMR i haven't really been up boulder or sail that much or at all for that matter but I'm sure you'll be able to find tons of spots up there. I think that theres more spots on boulder because its more of a mellow mountain where as sail and frisby ridge are more steep and cliffy.
Hope I could help and good luck with the jump.
