Blue Hole (New Jersey)
The Blue Hole is located in the Pinelands of Monroe Township, Gloucester County, New Jersey and Winslow Township, Camden County, New Jersey. It is a clear blue body of water situated in the middle of a dense forest, with many similar such lakes in its immediate vicinity. The water has warm and cold spots, averaging 58 to 60 degrees Fahrenheit. The color is very unusual, as most lakes and ponds in the area are brownish due to large deposits of bog iron and the presence of tannic acid. The Blue Hole is circular and about across. In the 1930s, the Blue Hole was a popular party and swimming spot. A wooden footbridge over the Great Egg Harbor River that once made the Hole easily accessible was wiped out by a storm in the 1960s; now it can only be reached on foot.
The Snow Hole
The Snow Hole is located in the Taconic Mountains, New York, USA along the ridge line between Bald Mountain and the White Rock (Taconic Mountains). It is a crevasse in which snow can be found well into the summer. The Snow Hole can be accessed by hiking the Taconic Crest Trail about 2.75 miles north from the Petersburgh Pass parking area just off of Route 2. The Snow Hole is located at . Finding the location of the Snow Hole can be confusing, as several maps (including Google maps and USGS Berlin quadrangle, 1:25,000 scale - 1988) mark the location of the Snow Hole "summit" at . However, that is a separate mountain summit and not the actual Snow Hole. The posted hiking map at the kiosk to the Taconic Crest Trail at Petersburgh Pass has the location correctly identified. Typically the crevasse has snow at the bottom of it year round.
