 Leonard Harrison State Park continued to attract national attention in the post @-@ war era . The New York Times featured the park and its " breath @-@ taking views of the gorge " as well as its trails and picnic groves in a 1950 article , and in 1966 praised the whitewater boating on Pine Creek and the park 's " outstanding look @-@ out points " . The Pine Creek Gorge , including Leonard Harrison and Colton Point State Parks and a 12 @-@ mile ( 19 km ) section of Tioga State Forest , was named a National Natural Landmark ( NNL ) in April 1968 . The plaque for the entire NNL is on the lookout terrace of Leonard Harrison State Park . Another New York Times article on whitewater canoeing in 1973 noted the damage along the creek done by Hurricane Agnes the year before , and Leonard Harrison 's waterfalls .
