Jackson Hole Ski Atlas
check out this site for all the areas backcountry (and resort sidecountry)...this site is sick and buy the atlas from Skinny Skis or Teton Mtn and such. It is an aerial view of all the lines.
There is parking on Teton Pass (get there early-9am as its competitive, especially weekends). Also parking lots halfway up both sides of the pass.
Easy access stuff off the pass is: to the south- Telemark and Chivers. To the North- boot pack up Glory (stairway to heaven) and come down Calverts ridge to the trees west of Twin Slide. You will see all the boot packs, both north ans south right outta the parking lot. BE CAREFUL as its obvious by looking at the atlas how large these slide paths are.
Targhee is a nice little resort, with fun lines. But if you are only there for 2 days...ski JH. The ghee is a long way from Jackson as the road goes...and its very similar to stuff we have here (colorado)
