Mount Frissell

Brace Mountain is the peak of a ridge in the southern Taconic Mountains, near the tripoint of the U.S. states of New York, Connecticut and Massachusetts. Its 2,311-foot (704 m) main summit is located in New York; it is the highest point in that state's Dutchess County.The New York and Massachusetts portions of the mountain are within protected areas; Taconic State Park and Mount Washington State Forest respectively. The Connecticut portions are privately owned and conserved. It is a challenging yet popular hike since its summit, along with 2,304-foot (702 m) subpeak South Brace Mountain, are along the 15.7 mi (25.3 km) South Taconic Trail. Hikers approach the mountain either from the New York side on the west via the South Taconic or from another trail following the Connecticut-Massachusetts state line on the east, a route that allows them to visit both the tristate marker and the highest point in Connecticut, near the summit of Mount Frissell, along the way. Brace's bald summit, marked by a large cairn, offers views in all directions, particularly to the Hudson Valley and Catskills to the west. It has become a popular site for launching hang gliders and paragliders.

The South Taconic Trail is a 21.3 mi (34.3 km) hiking trail in the Taconic Mountains of southwest Massachusetts and adjacent New York. The trail extends from Shagroy Road in Millerton, New York, north along the ridgecrest of the southern Taconic Range and the border of New York and Massachusetts, and ends north of the Catamount Ski Area on Massachusetts Route 23 700 feet (210 m) east of the New York border in Egremont, Massachusetts. The Appalachian Trail, which traverses an adjacent ridgeline in the same mountain range, parallels the South Taconic Trail 3 mi (4.8 km) to the east. The trails are connected to one another via shorter trails.

Bear Mountain is a peak of the southern Taconic Mountains in Salisbury, Connecticut. At 2,316 feet (706 m) (note, per references 1 and 3, there is disagreement about the precise elevation), Bear Mountain is the highest mountain that lies wholly within Connecticut. However, it is not the state highpoint: in the 1940s, the United States Geological Survey determined that the highest elevation in the state, at 2,380 feet (725 m), was actually on the nearby Connecticut-Massachusetts border, on the southern slope of Massachusetts’ Mount Frissell. There is a stone monument on the Bear Mountain summit. The Appalachian Trail crosses the mountain in a generally north-south direction.

Camp Hi-Rock is a YMCA summer camp for boys and girls in the Berkshires region of western Massachusetts. They were founded in 1948 around Plantain Pond on Mt. Washington.

Bingham Pond Bog is a rare undisturbed cold northern black spruce bog, highly unusual in that it lacks the usual sphagnum moss associated with bogs.

Boston Corner is a hamlet of the town of Ancram in Columbia County, New York, United States and the town of Northeast in Dutchess County. The District of Boston Corner was incorporated by Massachusetts in 1838 from a tract of unincorporated land west of the town of Mount Washington, Massachusetts, and was ceded from Massachusetts to New York on January 11, 1855, because its geographical isolation from the rest of Massachusetts made maintaining law and order difficult. Three railroads—New York Central's Harlem Line, the Poughkeepsie and Eastern Railway, and the Rhinebeck and Connecticut Railroad—once served the hamlet. The New York Central stop was called Boston Corners station. All lines have since been abandoned.

The Boston Corners station was a former New York Central Railroad station that served the residents of Ancram, New York.

Alander Mountain is 2,241-foot-tall (683 m) part of the south Taconic Mountains in southwest Massachusetts and adjacent 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 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.

The Mount Riga Ironworks was one of the most successful manufacturers of iron in the late colonial and post-Revolutionary period of United States history. Located in the far northwestern Connecticut town of Salisbury, it produced high quality iron for use in military and domestic applications, and supported a community of 1,200 people. It declined in the mid-19th century, and was closed in 1847. Surviving elements include an early 19th-century cold blast furnace and other foundational and archaeological remains. Its site, now part of a large private holding owned by the Mount Riga Corporation, was listed on the National Register of Historic Places in 1994.

Mount Riga State Park is an undeveloped public recreation area located in the town of Salisbury, Connecticut. The state park offers opportunities for hiking and bow hunting.
