Signal Mountain is an isolated summit standing 7,720 feet (2,350 m) abovesea level. The mountain is located inGrand Teton National Park in theU.S. state ofWyoming.[3] The next closest higher summit is more than 10 miles (16 km) distant, and this isolation provides sweeping views of theTeton Range, much of the northernJackson Hole area as well as theSnake River. Though located adjacent to the Tetons, Signal Mountain was not formed in the same manner or period. The mountain originally was formed by volcanic ashfall from one of the eruptions of theYellowstone hotspot. The peak is also partially a glacialmoraine formed by a receding glacier that came south out of theYellowstone icecap.[4] This same glacier also created neighboringJackson Lake.
Signal Mountain has a 5-mile (8.0 km) long road providing vehicular access to an observation area located just below the main summit. TheSignal Mountain Trail is a hiking trail that goes from Signal Mountain Lodge to the summit and covers a distance of 6.8 miles (10.9 km).[5] The trail splits mid-way for a portion of approximately 1.5 miles (2.4 km), allowing hikers to take either a trail along the lower part of the ridge or south of the ridge past a series of small ponds. The trails then rejoin and steepen over the last mile to reach the secondary summit of the mountain, the Jackson Lake Overlook. The trail rises approximately 800 feet (240 m) from the lodge to the overlook, though on the ridge trail there is quite a bit of up and down that adds a few hundred feet to thecumulative elevation gain. The trail is a hiking only trail,mountain biking andhorseback riding are not permitted by the park service. The road is a popular biking destination due to the difficult climb up and then (after turning around at the summit) continuous downhill experienced on a 3.5-mile (5.6 km) portion of the road.
