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.
Octopus Hole
Octopus Hole is a designated conservation area on the Washington's Hood Canal. It is located immediately off of Highway 101, just over three miles North of Hoodsport. The site is marked with conservation signs, an old sign from Mike's Dive Shop (now closed), and two very small parking areas on both lanes of the highway. Similar to the close-by Sund Rock conservation area, Octopus Hole is very popular with Scuba divers who enjoy diving the walls associated with the site to view various underwater creatures, including but not limited to Lingcod, Giant Pacific Octopus, Wolf Eel, sea cucumber, and nudibranch. The walls on this site are accessible as shore dives. To access the dive sites on the Hood Canal from the highway, divers must straddle the Highway 101 guard rail, then walk down the crude steps to the shore, some 20–30 feet below. There is no fee to access this site, which is publicly accessible.
