The Basin

The Basin is a giant pothole, a shape that forms where fast, falling water traps sand, gravel, and stones and spins them in a tight circle against the bedrock. Over enormous spans of time that swirling grit acts like a slow drill, grinding a round, smooth hollow into solid granite. The result at Franconia Notch is a bowl roughly thirty feet across with walls polished nearly glassy by the abrasion.

Geologists trace its beginnings to the end of the last ice age, when torrents of meltwater from the retreating glacier poured through the notch with tremendous force. The Pemigewasset River has kept the process going ever since, so the Basin is both an ice-age relic and a feature still being shaped by the water running through it today.

Reaching the Basin could hardly be simpler. A short, mostly level path leads from the parking area along the Franconia Notch bike path to viewpoints and railings around the bowl, making it accessible to almost everyone, including families with small children.

From the railings you look down into the smooth granite bowl as the river pours in through a narrow chute above and spins in the pool below before continuing downstream over more waterworn ledges. The rock is beautiful but treacherously slick when wet, which is why the viewing areas keep visitors safely back from the water.

The Basin sits in Franconia Notch State Park, a spectacular mountain pass squeezed between the Franconia Range and Cannon Mountain and threaded by a parkway. The notch is one of the scenic anchors of the White Mountains, and it packs an unusual number of natural attractions into a short stretch of road.

That makes the Basin a natural part of a larger day. Within the notch you can also visit the Flume Gorge, ride the tramway up Cannon Mountain, and remember the fallen Old Man of the Mountain, the granite profile that was the state's emblem until it collapsed in 2003. Strung together, they make Franconia Notch one of the great outings in New England.

The Basin, in Franconia Notch State Park in the White Mountains of New Hampshire, is a beautiful and famous natural granite pothole, a smooth, sculpted basin carved into the bedrock by the swirling waters of the Pemigewasset River over thousands of years.

Easily reached by a short walk, it is one of the most accessible and beloved natural wonders in the park. With its sculpted granite pothole and falls, the Basin offers a scenic destination in New Hampshire.

The Basin was formed over thousands of years as the waters of the Pemigewasset River, carrying sand, gravel, and stones, swirled against the granite bedrock below a waterfall, gradually grinding out a smooth, round, deep pothole in the rock. This process, aided by the glaciers and meltwaters that shaped the White Mountains, created the striking polished granite basin visitors see today. It is a classic example of the power of moving water and glacial forces to sculpt solid rock over immense time. Understanding this natural sculpting adds wonder to a visit to the Basin in Franconia Notch, New Hampshire.

You can walk the short, easy path to view the beautiful granite basin and its waterfall, admire the smooth sculpted rock and the clear swirling water, take photographs, and explore the nearby trails and connecting paths in Franconia Notch.
