The notch demarks the northeastern end of the Mahoosuc Range, and thus of the White Mountains.

Maine State Route 26 passes through the notch.

To the south, the notch drains into the Bear River, then into the Androscoggin.

On the northeast side, it includes the lowest slopes of Baldpate Mountain.

[2] The Appalachian Trail, a 2,170 miles (3,490 km) National Scenic Trail from Georgia to Maine, crosses the notch between Old Speck and Baldpate.
