Blue Hills Reservation is a 7,000-acre (2,800 ha)state park inNorfolk County, Massachusetts in the United States. Managed by theMassachusetts Department of Conservation and Recreation, it covers parts ofMilton,Quincy,Braintree,Canton,Randolph, andDedham. Located approximately ten miles south of downtownBoston, the reservation is one of the largest parcels of undeveloped conservation land within theGreater Bostonmetropolitan area. The park's varied terrain and scenic views make it a popular destination for hikers from the Boston area.[2]
Sailors along on the coastline noticed the bluish hue of the mountains, which is caused by the presence ofriebeckite,[3] giving the area its modern name.[2] The name of the state ofMassachusetts derives from theMassachusett Indian tribe's name of the hill:massa-adchu-es-et.[4] In 1893, theMetropolitan Parks Commission purchased the lands of Blue Hills Reservation as one of the state's first areas dedicated to public recreation.[2]
The practice ofFirst Day Hikes to markNew Year's Day with an outdoor activity began in 1992 at Blue Hills Reservation.[5] By the 2010s, the idea had spread and such hikes were taking place in state parks nationwide.[5]
Theecology of the Blue Hills is diverse and includesmarshes,swamps, upland and bottomlandforests,meadows, and anAtlantic white cedarbog. A number ofendangered species in Massachusetts, such as thetimber rattlesnake andcopperhead snake, reside in the reservation. Other flora and fauna includedogwood,lady's slipper,white-tailed deer,coyotes,wild turkey,red fox, andturkey vultures.[2]
