Nigel, here's a link to data on Grand Teton. But there are many other climbs there as well; here are those in Grand Teton National Park. Almost all (95%) of the climbs in Yellowstone are actually up-hill hiking. However, the Wind River Range and the Absaroka Range is rarely climbed. Or just visit here and get involved in the Pocatello Pump. Here's the latest PDF of the Massacre Rocks Climbing Guide. And there's always City of Rocks.

There's lots of climbing around here. Maybe after my knee operation on August 10 I can start doing some!
