Hamilton County

Hamilton County is a county located in the U.S. state of New York. Its county seat is Lake Pleasant. It is one of only two counties that lie entirely within the Adirondack Park (Essex is the other). As of the 2010 census, the population was 4,836, making it the least populous county in New York. It is also the most sparsely populated county in the eastern half of the United States, with a population density of just over three people per square mile.

Hamilton County is in the north central part of the state, northwest of Albany. It lies entirely within Adirondack Park and consists mostly of publicly owned parkland. As the tourist folk will tell you, there is no permanent traffic light in the county.

Sly Pond

The remote Sly Pond is one of the highest bodies of water in Adirondack Park at an elevation of 2,872 feet. It was once infamous for being a marker of how acidic Adirondack lakes had become by the eighties, with the DEC recording in 1980 the pond having an acidity of 3.54 which is about as "acidic as a dill pickle".

Revised map based on some analysis of I've been doing of photos I've taken over the years from the fire tower. Getting the view shed correct is a bit challenging using bare-earth digital elevation models, which do not fully consider the impact of trees blocking part of the viewable landscape.
