In the 1920s Clifford MacEvoy began buying up property and deeds to form the Bergen Country Hunting and Fishing Club. At about this time, a small pond located on the property called "Roten" pond, was dammed up to form the much larger Ramapo Lake, and some small parcels of land surrounding the lake were sold to private buyers for building lots, one including a television celebrity, lawyer and noted author. In 1924, at the top of the mountain he built a granite, brick and stucco manor house, designed by Mr. MacEvoy for his wife and his daughter. He named the estate RyeCliff after his wife's maiden name, Ryerson, and his first name, Clifford. Another mansion was also built on top of a hill overlooking Ramapo Lake, it was destroyed in a tragic fire one New Year's Eve many years later. The house includes a screened in porch, a large living room as well as a family room, each room with hand-hewn chestnut beams, a stone fireplace, and views of Ramapo Lake and the surrounding mountains to the west. At some point around 1920 – 1928 a tower was added to the top of the mountain. It was originally a water tower erected on the site of what is now the Wanaque Reservoir, built in the early 1900s by Clifford MacEvoy. Mr. MacEvoy relocated the tower to Ryecliff and enclosed it in mountain stone so as to blend in with the house itself as well as the natural environment. The Observation Tower stands high at a ground elevation of. Its five stories include two floors with toilet and, on the fifth floor, the room contains a fireplace. A hatch on the fifth floor leads to a roof with incredible views of Ramapo Park and Lake, the Wanaque Reservoir, mountains to the west and to the east, New York City. In 1976, the majority of Ryecliff's area was conveyed, by the trustee of the MacEvoy estate, to the State of New Jersey to become what is now the "Ramapo Mountain State Forest". The state forest built a network of hiking trails with the help of the New JerseyYouth Conservation Corps in 1978, some of which are still in use today. The forest was unfortunately sliced in two by the controversial extension of Route 287 in the early 1990s by the NJ Department of Transportation. A footbridge was built over the highway along the Cannonball Trail to mitigate this issue. Nestled at the top of the mountain, however the private Ryecliff estate, complete with tennis court, guest house, horse stable, private pond, and of course the Tower that can be seen for miles around. The Ryecliff estate has recently been put up for sale.
