Fowler Mountain, est. , is a traprock mountain located southeast of the center of Meriden, Connecticut. It is part of the narrow, linear Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border. Fowler Mountain is known for its rugged topography, unique microclimate ecosystems, and rare plant communities. It rises steeply above the Ulbrich Reservoir and the Quinnipiac River valley to the west. The mountain is traversed by the Mattabesett Trail. Geography 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 of basalt, 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. (See Metacomet Ridge for more information on the geology and ecosystem of Fowler Mountain). 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
