Roughly 0.75 miles in diameter, Chauncey Peak is located within the town of Meriden, Connecticut. Although Chauncey Peak is described by some sources as part of Lamentation Mountain, it rises more than above the common gap between the two, making it its own mountain by regional standards. Crescent Lake,, lies nestled between Lamentation Mountain and Chauncey Peak. The lake provides emergency drinking water to the city of Meriden. Much of the east side of the mountain has been subject to quarrying; as of 2007, the quarry was.5 mi wide, roughly 3/4 the width of the entire mountain. Interstate 91 cuts through the gap between Higby Mountain and Chauncey Peak to the north. The Metacomet Ridge continues north from Chauncey Peak to become Lamentation Mountain and south to become Higby Mountain. The western half of Chauncey Peak drains into the Quinnipiac River, then to Long Island Sound; the eastern half to the Mattabesett River, thence to the Connecticut River and Long Island Sound.
Geology and environment
The origin of Chauncey Peak and the Metacomet Ridge dates back 200 million years ago with the rifting apart of North America from Eurasia in the process that would ultimately create the Atlantic Ocean. In the area that is now the Metacomet Ridge and surrounding sedimentary rock basin, massive basalt lava flows spread across the prehistoric rift valley, some of them several hundred feet thick, over a period of 20 million years. Sediment accumulated between lava flows and lithified into sedimentary rock. After the rifting processes ceased, layers of strata faulted and tilted upward. Subsequent erosion, glaciation, and uplift exposed the weather resistant edge of the traprock lava sheets, creating the cliffline of the Metacomet Ridge as it is today. The mineral content and the shape of the ridge make possible a variety of microclimate ecosystems. Hot and dry cliff faces support plant and animal species uncommon so far north. Deeply gouged ravines support cooler climate species found in more northerly climes, while gradual backslope environments support species typical of the surrounding latitude. Talus slopes beneath cliffs accumulate minerals that support alkaline-loving plant species uncommon in surrounding acidic southern New England. Extensive cliffs provide ideal habitat and important migration corridors for raptor species.
Recreation and conservation
The west side of Chauncey Peak lies within Giuffrida Park, managed by the city of Meriden. The park boasts a lake, golf course, woodlands, and the rocky peaks of Lamentation Mountain and Chauncey Peak. Permitted activities within the park include hiking, snowshoeing, cross-country skiing, picnicking, and bicycling. Swimming, boating, rock climbing, and fishing are prohibited. The park supports a number of trails, most notably the Mattabesett Trail, which stretches from the northern end of Lamentation Mountain, south to Totoket Mountain and north again to the Connecticut River. Trailhead parking for Chauncey Peak is located at Giufridda Park on Westfield Road, east of its junction with U.S. Route 5 and west of Interstate 91, exit 20, via Country Club Road. The ecosystem and ridgeline of Chauncey Peak is most threatened by quarrying, although the west side of the peak, within Giuffrida Park, is protected. In 2000, Chauncey Peak was included in a study by the National Park Service for the designation of a new National Scenic Trail now tentatively called the New England National Scenic Trail, which would include the Metacomet-Monadnock Trail in Massachusetts and the Mattabesett Trail and Metacomet Trail trails in Connecticut.
