Located within the towns of Durham and Wallingford, Connecticut, Fowler Mountain is long by wide, although rugged topography makes the actual square mileage much larger. Fowler Mountain is an important aquifer; two reservoirs lie at the base of it: Ulbrich Reservoir to the west, in the town of Wallingford and Pistapaug Pond to the south, between Fowler Mountain and Pistapaug Mountain. The mountain is largely wooded with a few lookouts from rugged ledges over the reservoirs below. The Metacomet Ridge continues north from Fowler Mountain as Trimountain and south as Pistapaug Mountain. The western half of Fowler Mountain drains into Muddy River, then into the Quinnipiac River, thence to Long Island Sound; the east side drains into the Coginchaug River, thence into the Connecticut River and Long Island Sound.
Geology and ecology
Fowler Mountain, like much of the Metacomet Ridge, is composed ofbasalt, also called traprock, a volcanic rock. The mountain formed near the end of the Triassic Period with the rifting apart of the North American continent from Africa and Eurasia. Lava welled up from the rift and solidified into sheets of strata hundreds of feet thick. Subsequent faulting and earthquake activity tilted the strata, creating the cliffs and ridgeline of Fowler Mountain. Hot, dry upper slopes, cool, moist ravines, and mineral-rich ledges of basalt talus produce a combination of microclimate ecosystems on the mountain that support plant and animal species uncommon in greater Connecticut. Fowler Mountain is also an important raptor migration path..
Recreation and conservation
Much of the summit and the west side of Fowler Mountain has been conserved as part of the undeveloped Trimountain State Park and as municipal watershed land. Suburban housing occupies the lower slopes of the east side of the mountain. Activities enjoyed on the mountain include hiking, snowshoeing, picnicking, and other passive pursuits. Swimming, boating, and fishing are prohibited in the reservoirs. The Mattabesett Trail, which stretches from the northern end of Lamentation Mountain, south to Totoket Mountain and north again to the Connecticut River, traverses the ridgeline of Fowler Mountain. A trailhead can be found on the south side of Fowler Mountain where the blue blazed Mattabesett trail crosses Howd Road after descending from Pistapaug Mountain. After traversing Fowler Mountain the trail continues directly to Trimountain; a trailhead can be found on route 68 after this traversal. Threats to the ecosystem of Fowler Mountain include development and quarrying. In 2000, Fowler Mountain 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. The and the have been active in conserving the viewshed of Fowler Mountain.
