Signal Mountain is an isolated summit standing 7,720 feet (2,350 m) above sea level.

[3] The next closest higher summit is more than 10 miles (16 km) distant, and this isolation provides sweeping views of the Teton Range, much of the northern Jackson Hole area as well as the Snake River.

The peak is also partially a glacial moraine formed by a receding glacier that came south out of the Yellowstone icecap.

Signal Mountain has a 5-mile (8.0 km) long road providing vehicular access to an observation area located just below the main summit.

The trails then rejoin and steepen over the last mile to reach the secondary summit of the mountain, the Jackson Lake Overlook.
