It is in North Elba, New York on land owned by the Adirondack Mountain Club.

The Adirondack Loj and Heart Lake are at the foot of Mount Jo.

A steep but short and relatively easy hike compared to other mountains in the area, the Mountain offers great views of the High Peaks region, including Cascade Mountain, Mount Marcy, Algonquin Peak, Mount Colden and Indian Pass.

The climb offers one of the best views for the effort (a 710-foot (220 m) vertical ascent from the Loj – actual trail distance is approximately 2.6 miles roundtrip), with a sweeping vista of the Great Range of the Adirondacks.

The mountain was named in 1877 by Henry Van Hovenberg, who built the original Adirondack Loj, for his fiancée Josephine Schofield, who died shortly before they were to have been married.
