Mount Timpanogos, sometimes informally referred to as Timp, is the second highest mountain in Utah’s Wasatch Range. Timpanogos rises to an elevation of 11,752 ft (3,582 m) above sea level in the Uinta-Wasatch-Cache National Forest. With 5,270 feet of topographic prominence, Timpanogos is the 47th-most prominent mountain in the contiguous United States. The mountain towers over Utah Valley, including the cities of Lehi, Provo, Orem, Pleasant Grove, American Fork, Lindon and others. Although it is a 14-mile round-trip hike, with almost a mile of elevation gain, Timp’s summit is one of the most-visited in the Rocky Mountains. There are two main trails to the top: the first starts at Aspen Grove with a trailhead elevation of 6,910 feet (2,106 meters), and the second starts at the Timpooneke campground in American Fork Canyon at 7,370 feet (2,185 meters). The two trails are nearly the same length. Hikers on the trails climb through montane forest, subalpine and alpine zones. The hike is marked by waterfalls, conifers, rocky slopes and ridges, mountain goats, and a small lake, Emerald Lake, at 10,380 feet (3,164 m). A short diversion will lead hikers past a World War II bomber crash site. Other climbing routes exist on the mountain, but they are more technically demanding and require special skills and mountaineering gear.
