Northern Rockies: Utah, Wyoming, Idaho, Montana: Tetons & Wind Rivers, Wyoming
The Tetons, located in Grand Teton National Park, are some of the most famous and often photographed mountains in America; and rightfully so. The jagged peaks tower 7,000 feet directly above the broad Jackson Hole Valley and are some of the few peaks in the lower 48 states that could possibly be mistaken for the European Alps.
The Wind River Range, in western Wyoming, is an enormous mountain range that stretches 110 miles. The range's crest forms the Continental Divide and includes Wyoming's tallest peak, Gannett Peak. The northern part of the range contains several of the largest glaciers in the Rocky Mountains, as well as the impressive headwaters of the Green River. The southern part of the range holds the jagged Cirque of the Towers, certainly one of the premiere cirques of the Rocky Mountains. The entire range, fresh from glaciation, is incredibly rocky and rugged, making the views spectacular but the travel difficult.
