LONESOME LAKE (NEW HAMPSHIRE)

'Lonesome Lake' is a 12.2-acre water body located in Franconia Notch in the White Mountains of New Hampshire, south of Cannon Mountain. The lake is reachable by hiking trails from the Franconia Notch Parkway and features an Appalachian Mountain Club hut on its southwest shore.
The lake lies in the Merrimack River watershed. Its outlet, Cascade Brook, flows south over ledges and waterfalls to the Pemigewasset River near "The Basin" in Franconia Notch. The Pemigewasset in turn flows south to the Merrimack River, which reaches the Atlantic Ocean at Newburyport, Massachusetts.
Lonesome Lake is part of Franconia Notch State Park. The Appalachian Trail passes the lake at its outlet. Additional hiking trails travel north to Cannon Mountain.
