the long ridge of Brodie Mountain. The area hosts three long distance trails (the Appalachian Trail, the Taconic Crest Trail, and the Taconic Skyline Trail) and an extensive network of smaller trails. Southern Vermont North of the Massachusetts border, the profile of the Taconic Range is cut and eroded by the Hoosic River as it turns west and then south toward its confluence with the Hudson River, and by its tributary rivers in the vicinity of Bennington, Vermont. Mount Anthony , notable for its caves and as the location of Southern Vermont College, stands as a satellite peak above the surrounding eroded terrain. North of Bennington, the range gradually rises to its highest prominence with peaks such as Mount Equinox , the high point of the Taconic Mountains, and Dorset Mountain , a New England 100 Highest list summit. Other notable summits include Grass Mountain , a New England Fifty Finest list mountain; and Mount Aeolus , the location of several defunct marble quarries and the site of Aeolus Cave an important bat hibernaculum. Designated hiking trails are located on Mount Equinox, Dorset Mountain, and Mount Aeolus, and several other peaks within the region. Northern terminus Immediately north of Danby, Vermont, the Taconic Range broadens and becomes shorter for a time. It exhibits several parallel ridgelines, dominated to the west by mountains composed of slate and similar rock, most notably the ridgeline of Saint Catherine Mountain , with its conspicuous long cliff face visible from Wells and Poultney. The area around Lake Saint Catherine contains extensive slate quarries. The ridgeline to the east, composed of schist and phyllite, is dominated by the escarpment of Tinmouth Mountain , overlooking the Valley of Vermont to the east in the town of Tinmouth. A field of less descript ridges and peaks lies between these two summits. Near the end of the range, in the vicinity of Rutland, Vermont, the Taconic Mountains show several prominent peaks with dramatic, irregular cliff faces clearly visible from U.S. Route 4 west of the city of Rutland; these include Herrick Mountain ; Grandpa's Knob , the former site of the Smith–Putnam wind turbine, the first large-scale electricity-producing wind turbine; and the butte-like Bird Mountain (also called Birdseye Mountain) , home of the Bird Mountain Wildlife Management Area and notable as an important raptor migration path and nesting site. Also part of the Taconic Mountains are the foothills of
