Alander Mountain

Alander Mountain is a 2,241-foot-tall (683 m) part of the south Taconic Mountains in southwest Massachusetts and adjacent to New York. The summit is grassy and covered with scrub oak and shrubs; the sides of the mountain are heavily forested. Several trails traverse Alander Mountain, most notably is the 15.7 mi (25.3 km) South Taconic Trail, which passes just beneath the summit.

Much of the mountain is located within Taconic State Park and Mount Washington State Forest; other parcels are privately held.

The west slope of Alander is within Copake, New York. The point where the state line crosses the ridge next to the South Taconic Trail is, at 2,115 feet (645 m), the highest elevation in Columbia County. The summit and east side are within the town of Mount Washington, Massachusetts. The west side of Alander Mountain drains into the Preachy Hill Brook, then into the Noster Kill, Bash Bish Brook, the Roeliff Jansen Kill, thence the Hudson River and Long Island Sound. The east side drains into Ashley Hill Brook, then Bash Bish Brook and the Roeliff Jansen Kill.
