Moss Island, National Natural Landmark in Little Falls, New York.
Moss Island is a natural island in Little Falls defined by deep geological formations including glacial potholes between the Mohawk River and Barge Canal. The southern cliffs rise prominently and display metasyenite rock walls with distinctive circular formations carved into the surface.
The island formed when canal locks were built in 1793 to help boats navigate around the Mohawk River falls, transforming the landscape. This engineering project became a turning point in regional waterway development and shaped how the land was used afterward.
Rock climbers gather at the metasyenite cliffs, where over 100 different climbing routes range from beginner to advanced levels.
Access to the island is via a walkway beside the canal gate, which crosses the waterway system and connects to the site. Free parking is available on-site, making a visit convenient without extra expenses.
The southern rock wall displays impressive circular indentations that extend unusually deep into the stone, making the island geologically distinctive. These formations developed through natural erosion and draw the attention of geology enthusiasts and curious visitors alike.
