Mount Washington Hillclimb Auto Race

The Mount Washington Auto Road—originally the Mount Washington Carriage Road—is a 7.6 mi (12.2 km) toll road in southern Coos County, New Hampshire that extends from New Hampshire Route 16 in Green's Grant, just north of Pinkham Notch, westward across Pinkham's Grant and Thompson and Meserve's Purchase to the summit of Mount Washington in the White Mountains of the US state of New Hampshire. The road climbs 4,618 ft (1,408 m) from an altitude of 1,527 ft (465 m) at the bottom to 6,145 ft (1,873 m) at the top, an average gradient of 11.6%. The road was completed and opened to the public in 1861.

As of the 2020 census, the population of the purchase was 1.In New Hampshire, locations, grants, townships (which are different from towns), and purchases are unincorporated portions of a county which are not part of any town and have limited self-government (if any, as many are uninhabited). Thompson and Meserve's Purchase is notable for encompassing the northern slope of Mount Washington, including a large portion of the Mount Washington Auto Road and Cog Railway.

The Great Gulf is a glacial cirque, or amphitheater-like valley head formed from a glacier by erosion, located in the White Mountains of New Hampshire. The cirque's walls are formed, from south to north, by the mountainsides of Mount Washington (6,288 ft; 1,917 m), Mount Clay (5,533 ft; 1,686 m), Mount Jefferson (5,716 ft; 1,742 m), Mount Adams (5,799 ft; 1,768 m), and Mount Madison (5,366 ft; 1,636 m). It is drained by the West Branch of the Peabody River. The Great Gulf Wilderness is a protected wilderness area encompassing the cirque of the Great Gulf, and is part of the National Wilderness Preservation System. Established in 1964, Great Gulf is New Hampshire's oldest and smallest wilderness area, comprising just 5,552 acres (22.47 km2).

Mount Adams, elevation 5,793 feet (1,766 m) above sea level, is a mountain in New Hampshire, the second highest peak in the Northeast United States after its nearby neighbor, Mount Washington. Located in the northern Presidential Range, Mount Adams was named after John Adams, the second President of the United States. It was given this name on July 31, 1820. To the northeast is Mount Madison and to the southwest is Mount Jefferson. From the summit, Mount Washington can be seen directly to the south. There are two major subsidiary peaks of Mount Adams: Mount Sam Adams and Mount Quincy Adams, named after John Adams' cousin, Revolutionary leader Samuel Adams, and son, President John Quincy Adams, respectively, and two minor sub-peaks, Abigail Adams (named for John Adams' wife Abigail) and Adams 5. The northern side of the mountain ridge is located in Low and Burbank's Grant, and the end of Durand Ridge, and King Ravine, on the north side of Mount Adams are in the town of Randolph (formerly Durand). The entire south side of the mountain ridge is in Thompson and Meserve's Purchase. The Appalachian Trail traverses the col between Mount Adams and Mount Sam Adams on the Gulfside Trail. The Randolph Mountain Club (RMC) maintains the trails and several huts and shelters high on Mount Adams' north side, including "The Perch", "Crag Camp", "The Log Cabin", and "Gray Knob". A large network of hiking and climbing paths lead south to the huts and ridges from several parking areas located on U.S. Highway 2. The Aetherius Society claims that Mount Adams is one of 19 "holy mountains" around the world.

Mount Madison is a 5,367-foot (1,636 m) mountain in the Presidential Range of New Hampshire in the United States. It is named after the fourth U.S. President, James Madison. Mountains in the Presidential Range are named for U.S. presidents, with the tallest (Mount Washington) named for the first president, the second tallest (Mount Adams) for the second president, and so on. However, due to a surveying error, Mount Monroe, named after the fifth president, James Monroe, is actually 22 feet (6.7 m) taller than Mount Madison. There are many hiking trails on the mountain. A stretch of the Appalachian Trail traverses just below its summit on the Osgood Trail. The Madison Spring Hut, maintained by the Appalachian Mountain Club, is nestled between Mount Madison and Mount Adams and provides rustic lodging in the summer. Reservations generally need to be made far in advance. Mount Madison is the northernmost peak in the Presidentials. Like most of the range, its summit is above treeline. Due to high winds and low temperatures, hypothermia is a danger even in the summer.

Pinkham's Grant is a township in Coös County, New Hampshire, United States. The grant lies entirely within the White Mountain National Forest. As of the 2020 United States census, the population of the grant was zero.In New Hampshire, locations, grants, townships (which are different from towns), and purchases are unincorporated portions of a county which are not part of any town and have limited self-government (if any, as many are uninhabited).

Mount Jefferson is located in Coos County, New Hampshire, and is the third highest mountain in the state. The mountain is named after Thomas Jefferson, the third president of the United States, and is part of the Presidential Range of the White Mountains. Mount Jefferson is flanked by Mount Adams (to the northeast) and Mount Clay (to the south). The mountain has several interesting features, making it a popular hike. Two distinct ridges lead to its summit: Ridge of the Caps and Castle Ridge. The mountain is surrounded by the three dramatic glacial cirques of Jefferson Ravine, Castle Ravine, and the Great Gulf. 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. Mount Jefferson has a direct ascent along the Caps Ridge Trail, whose base, Jefferson Notch, is the highest point of any public road in New Hampshire at 3,009 feet (917 m). 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.

The New River is a 2.2-mile-long (3.5 km) stream in the White Mountains of New Hampshire in the United States. It is a tributary of the Cutler River, part of the Saco River watershed flowing to the Atlantic Ocean in Maine. The river is within the townships of Sargent's Purchase and Pinkham's Grant in Coos County. The New River rises in the Gulf of Slides, a small glacial cirque at the foot of Boott Spur, a southern extension of Mount Washington. Flowing northeast, the stream drops rapidly down the western slopes of Pinkham Notch, joining the Cutler River in the floor of the notch at the Route 16 crossing, just south of the notch's height of land, and just upstream from the Cutler River's merging with the Ellis River.

The West Branch of the Peabody River is a 5.8-mile-long (9.3 km) river in the White Mountains of New Hampshire in the United States. It is a tributary of the Peabody River, which flows into the Androscoggin River, which in turn flows east and south into Maine, joining the Kennebec River near the Atlantic Ocean. The West Branch of the Peabody is within the Great Gulf Wilderness of the White Mountain National Forest for most of its length. It is paralleled by the Great Gulf Trail, a popular route for backpackers. The stream rises in Great Gulf, a large glacial cirque on the northern side of Mount Washington. The West Branch flows from the outlet of Spaulding Lake, a tarn seated at the foot of the east face of Mount Clay, and proceeds northeast deeper into the gulf, with Mount Jefferson of the Presidential Range to the west and Chandlers Ridge, a northern spur of Mount Washington, to the east. Upon reaching the outlet of Jefferson Ravine, the river turns east, with Mount Adams and Mount Madison rising above its northern bank. The river ends at the Peabody River, 1.5 miles (2.4 km) north (downstream) of Glen House, the entrance to the Mount Washington Auto Road.
