These four parcels of special land located on Entrance Mountain are important scenic and natural areas. One 48-acre parcel is located on the ridge-top and west-facing side of the mountain. This is the north knob of the mountain. A second 32-acre parcel is on the eastern face of the mountain and can be seen from many locations on Mount Constitution. The third 10-acre parcel on its northern flanks can be spotted from Cascade Lake. In January 2008, an adjacent 36 acres was donated by the William Halpenny Estate. The Halpenny addition has rugged topography and is heavily forested. Of particular note is the prevalence of Sitka spruce and scattered areas of mature big leaf maple. At higher elevations, slide chutes and boulders are coated by lush moss, adding another element to the land’s many-textured features and providing an array of opportunities for wildlife.
