Cannon Cliff

Overview

Cannon Cliff is the sheer granite wall that defines the heart of the Notch. It’s where the Old Man of the Mountain once gazed over Profile Lake, and it remains the park’s most dramatic rock face—part natural icon, part open‑air geology lab.

What You’ll See

From Profile Lake you’re staring straight up at thousands of feet of Conway Granite, with big talus aprons sloping away at the base. Interpretive “profilers” nearby recreate the Old Man’s silhouette when viewed from the right height, a surprisingly moving nod to the lost profile. Some visitors also keep an eye out for the lesser‑known “Old Woman on the Notch,” a separate rock profile locals call the Watcher.

Geology & Story

The cliff is Jurassic‑age Conway Granite, pinkish from feldspar. Glaciers carved the U‑shaped valley and left steep walls that still shed rock, feeding the talus fans below. Freeze–thaw and long‑term weathering sculpted the Old Man’s five stacked ledges; despite stabilization hardware, the lower blocks finally failed on May 3, 2003. Today, ongoing studies use tools like 3D modeling, GPS surveying, and thermal imaging to better understand how Cannon Cliff evolves over time.

Getting There & Logistics

For the smoothest approach, use Exit 34B and park at the Old Man of the Mountain Historic Site. Walk around the Profile building to Profile Lake—the climbers’ path to the cliff starts here. The Profile building has seasonal restrooms. There’s also a southbound‑only pull‑off signed for Profile Lake Trailhead; it’s handy but light on amenities. Never park on the Parkway shoulder anywhere in the Notch; if lots are full, use overflow at Exit 34C (Cannon Main Base). On peak weekends and holidays, a paid hiker shuttle runs—arrive early and build in time to move your car.

For Climbers and Photographers

Cannon Cliff’s reputation for big‑wall granite is well earned, and the lakeside vantage offers classic photographs of the cliff reflecting in calm water. Expect a climbers’ path from the lake rather than a manicured walkway.

Best Time to Visit

Crowds spike in October foliage season; mornings are the least hectic and give you calm light across Profile Lake. When the tram is operating (typically late spring through fall) and in beach season at Echo Lake, bathrooms nearby are available; outside those windows, plan ahead for limited facilities.
