In the beginning, small sawmills provided lumber for local use. After the Civil War, large lumber companies formed and mills were built near the Glens Falls area. At first logging was prevalent along the upper Hudson River which was used to float the logs to the mills. Later, logging operations moved into Lake Pleasant, and the Sacandaga River, the outlet of Lake Pleasant, was used to float logs to Glens Falls as the state of New York designated rivers as public highways for moving logs to the larger companies. Many local farmers found winter employment as lumberjacks, and also supplied the companies with potatoes, meat, animal feed and dairy products. The lumber companies bought large parcels of land for their timber. Some of this land was later abandoned and became state land. This was the beginning of the Adirondack Park as designated in 1892.
