Mount Jefferson is located in Coos County, New Hampshire, and is the third highest mountain in the state.

Finally, Monticello Lawn is a large expanse of alpine sedge and rush near the otherwise talus-covered summit cone.

When viewed from the Mount Washington Auto Road, Jefferson features an arrow-shaped bald patch pointing to its summit.

This route, gaining only 2,700 feet (823 m) vertically to the summit, results in it having the least distance of ascent of any Presidential mountain (about 2.5 miles).

However, climbing over the "caps" involves some exposed scrambling and can be steep and challenging at times.
