Manitook Mountain
Encyclopedia
Manitook Mountain, also called Manituck Mountain, 638 feet (194.5 m), is a 1.6 miles (2.6 km) long traprock mountain ridge located between the Berkshires and the Connecticut River Valley in north-central Connecticut
. It is an outlying ridge belonging to 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. Manitook Mountain is known for its ledges and microclimate
ecosystems. The mountain has no official trail.
, its northern summit abuts the Connecticut/ Massachusetts border near Southwick, Massachusetts
. The mountain is particularly prominent as viewed from the Congamond Lakes to the north.
The north side of the mountain drains into the Congamond Lakes then into Great Brook, thence to the Westfield River
, the Connecticut River
, and Long Island Sound
. The remainder of the mountain is of the Salmon Brook watershed, which drains into the Farmington River
, thence into the Connecticut River.
, also called traprock, a volcanic rock. The mountain formed near the end of the Triassic Period with the rifting apart of the North America
n 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 Manitook 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. Manitook Mountain is also an important raptor migration path. (See Metacomet Ridge

Geology and ecology
Manitook Mountain, like much of the Metacomet Ridge, is composed of basaltBasalt
Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey...
