The Metacomet Ridge extends north from West Rock Ridge as Mad Mare Hill and Mount Sanford and northeast as Rocky Top and Sleeping Giant. East of West Rock Ridge, the Metacomet Ridge spreads out into a series of low, parallel ridges toward Saltonstall Mountain in Branford, Connecticut; the only noteworthy summit in between is East Rock which looms over New Haven from the north. The west side of West Rock Ridge drains into West River, then into Long Island Sound; the east side into Belden Brook thence to West River, and the north side into Mill River thence to New Haven Harbor and Long Island Sound.
