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.
Great Blue Hill
Great Blue Hill (called Massachusett by Native Americans) is a hill of 635 feet (194 m) located within the Blue Hills Reservation in Milton and Canton, Massachusetts 10 miles (15 km) southwest of downtown Boston. It is the highest point in Norfolk County. The modern name for the hill was given by early European explorers who, while sailing along the coastline, noticed the bluish hue of the exposed granite faces when viewed from a distance (due to Riebeckite). The Blue Hills' eastern slopes face the ocean and lie within Quincy. The area attracted quarrying for its "blue granite".
The name of the Massachusett Indian tribe and their language (and thus the name of the Bay, Colony, Commonwealth/State, etc.) derive from the Massachusett name for the hill: "massa-adchu-es-et", where "massa-" is "large", "-adchu-" is "hill", "-es-" is a diminutive suffix meaning "small", and "-et" is a locative suffix, identifying a place.
