Blue Hole (Castalia)
The Blue Hole is a fresh water pond located in Castalia, Erie County, Ohio, in the United States. From the 1920s to 1990 the Blue Hole was a tourist site, attracting 165,000 visitors annually at the height of its popularity, partly because of its location on State Route 269, about southwest of the Cedar Point amusement park in Sandusky, Ohio.
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.
