Rocky Hill Ridge, also known as the Mount Lucas-Rocky Hill Ridge,[1][2] named after Lucas Voorhees, an 18th-century landowner,[3] is a diabasetrap rockridge running west to east in the US State of New Jersey. Diabase intrusions form Baldpate Mountain and Pennington Mountain, the Mount Rose extension of the Mount Lucas-Rocky Hill ridge, and part of the Sourland Mountains.[4] The Ridge is nine miles (14 km) long[5] and continues across the Millstone River, just below The Georgetown Franklin Turnpike, as the Ten-Mile Run Mountain and Lawrence Brook Mountain.[6] The western section of the ridge, which runs to the northwest to The Sourlands (although not connecting with it because of the Hopewell Fault[7]), is the Mount Rose section of the ridge.[8]
