feet thick. Subsequent faulting and earthquake activity tilted the strata, creating the dramatic cliffs and ridges of Bare 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 Massachusetts. (See Metacomet Ridge for more information on the geology and ecosystem of Bare Mountain.) See also Bare Mountain (disambiguation) is also the name of several other mountains in the United States.
