Jayne's Hill has been known by several different names. In 1825 Long Island historian Silas Wood called it "Oakley's High Hill Field" with a surveyor telling him it was. At the time it was considered the third highest point on Long Island behind Harbor Hill in Nassau County and Layton Hill's in Wheatley, New York. Walt Whitman was born near the site of Jayne's Hill, and visited the summit. In 1881, Whitman wrote: "I write this back again at West Hills on a high elevation Of Jayne's Hill.... A view of thirty of forty, or even fifty or more miles, especially to the east and south and southwest: the Atlantic Ocean to the latter points in the distance - a glimpse or so of Long Island Sound to the north." In 1887, it was reported to be in the Brooklyn Daily Eagle, only one foot shy of the reported height of Harbor Hill. In 1901 the Brooklyn Daily Eagle reported that Jayne's Hill was the tallest. Subsequent surveys by the USGS of Harbor Hill show it to be and Layton's Hill as. The New York Times in 1980 said it was. In more recent times, in 1980, a plan to place a radio toweron top of Jayne's Hill as one of a series of police radio towers was foiled when environmentalists and residents physically blocked county bulldozers. Regardless, a water tower was erected in 1998. This in combination with forest growth overtaking the grasslands once present on the hill severely restrict the views once beheld by Whitman.
Present day
As part of West Hills County Park, the summit is located on public land and lies along the white-blazed Walt Whitman trail. The closest parking is at the end of Reservoir Road, West Hills, NY near the private grounds of a county water tower. The park is open until dusk. Passing through two series of metal gates, one may reach the summit within a matter of minutes along the trail, with very little elevation to tackle along the way. The summit is marked by a boulder bearing a plaque inscribed with Walt Whitman's poem "Paumanok" from Leaves of Grass. Unfortunately as of 2010, some vandalization has occurred at the area, as previously existing wooden fences and signage are missing, as well as the boulder itself being marked with spray paint. If proceeding further than Jayne's Hill along the trail system, one should take caution as there are a few missing blazes, as well as several bridle paths in current use by horses which intersect the hiking trails.
