The Bigelow Mountain Shelter, pictured here sometime in the 1950s, was removed from the Appalachian Trail in the 1960s. It is a typical version of the log sided Adirondack style lean-to favored by the early shelter builders. It was located just south of the current Horns Pond Shelter.

From the back of the image: "Lean-to on the Appalachian Trail on the conifer-covered slopes of Mt. Bigelow in Maine. Here the Appalachian Trail and the Bigelow Range Trails meet, affording a crest line route of 20 miles along Mt. Bigelow."

The Limestone Spring Shelter is located in Connecticut and is more than half a mile off the current route of the Appalachian Trail on a blue blazed trail that was once the main route of the Trail. This shelter is maintained by the Appalachian Mountain Club.

Lakes of the Clouds Hut, built in 1915, is the highest elevation hut in the chain of shelters maintained by the Appalachian Mountain Club in the White Mountains of New Hampshire. The current structure, which has been substantially renovated several times over the years, is built on the site of an earlier shelter constructed in 1901. The hut sleeps 90, and sits at an elevation of 5,030'. Due to the often extreme weather conditions at these elevations, this hut is only open May 31-September 15 each year. Like all AMC huts, a stay at Lakes of the Clouds Hut includes dinner and breakfast (included in the fee for overnight stays).
