Jackson Hole—Sandwiched between three mountain ranges, Jackson Hole is a lush valley about 50 mi/80 km long (hole means "valley" in trappers' lingo). The valley, the town and the lake were all named after the same mountain man, Davey Jackson. A large portion of Jackson Hole was purchased by John D. Rockefeller Jr. in the late 1920s and 1930s, and it eventually became a sizable part

of the national park. (The town of Jackson and other parts of Jackson Hole He outside the park boundaries.) Throughout the valley, you'll see moose, mule deer, pronghorn sheep and elk. The area is also a sanctuary for bald eagles, trumpeter swans, black bears, grizzlies and bison. You'll find plenty of opportunities for fishing, white-water rafting and horseback riding in the area.
