Lantern Hill

[4] The hill is composed mostly of high-purity milky quartz and it occupies the inactive Lantern Hill Fault, which runs south into the Atlantic Ocean.

Analysis of the quartz reveals that it is 238 million years old—the mid-Triassic Period of the Mesozoic Era in geologic time, according to current theories.

[5] [6] David D. Mallory began commercial mining of the hill's silica in 1870 (Haynes and Boylan 1976);[7] the quarry closed when the Mashantucket Pequots acquired the land in 1994.

Lantern Hill is the southwestern terminus of the Narragansett Trail, a hiking path maintained in Connecticut by the Connecticut Forest and Park Association (CFPA 2005).

[8] The hilltop offers views of the Atlantic Ocean and the surrounding countryside, including the Mashantucket Pequots' Lantern Hill Reservation, the Mashantucket Museum and Research Center, and the Foxwoods Resort and Casino.
