Crawford Notch is a major pass through the White Mountains of New Hampshire, located almost entirely within the town of Hart's Location. Roughly half of that town is contained in Crawford Notch State Park. The high point of the notch, at approximately above sea level, is at the southern end of the town of Carroll, near the Crawford Depot train station and Saco Lake, the source of the Saco River, which flows southward through the steep-sided notch. North of the high point of the notch, Crawford Brook flows more gently northwest to the Ammonoosuc River, a tributary of the Connecticut River.
