prior to the extraction of coal in the mid-Appalachians. Highland areas were also burned of timber when lowland fires, set to clear land for farms, raged out of control. However, by the early 20th century, after agricultural interests shifted west and charcoaling became unprofitable, rural New England became largely forested again. A 2004 ecological resource study conducted for the National Park Service suggests that the Metacomet Ridge may have remained more or less forested (cleared only intermittently) throughout New England's agricultural period, thereby allowing the area to retain its biologic diversity through the 20th century. Increasing urbanization and industrialization in 19th century New England resulted in an opposing aesthetic transcendentalist movement characterized by the paintings of the Hudson River School of American landscape painters such as Frederic Edwin Church and Thomas Cole (who, in 1836, famously painted the Connecticut River from sketches he made from the summit of Mount Holyoke), the work of landscape architects such as Frederick Law Olmsted, and the writings of philosophers like Henry David Thoreau and Ralph Waldo Emerson. This philosophical, artistic, and environmental movement transformed many areas of the Metacomet Ridge (as well as other places in New England) from a commercial resource to a recreational and aesthetic resource. Hotels, parks, and summer estates were built on the mountains from the mid-1880s to the early 20th century. Route 47 borders its west end. Down its middle is cut Route 116 from South Hadley to Amherst. Formerly, along the east edge of this highway ran the Holyoke to Amherst trolley tracks. The bed is still visible along most of its mountain route. The Mount Holyoke Summit House In 1821, an guest cabin was built on Mount Holyoke by a local committee—one of the first New England summit houses. The property changed hands several times between 1821 and 1851 when it was bought and rebuilt as a two-story, eight-room hotel. Local entrepreneurs John and Frances French were the primary owners; between 1851 and 1900, the hotel and property were subject to a number of upgrades and related construction projects including a covered tramway to the summit of the mountain (first drawn by horse, then mechanized), a railroad from the base of the mountain to a steamboat dock on the Connecticut River, and the construction of a number of outbuildings and trails. With passenger steamship to the connecting summit railway established, the Mount Holyoke "Prospect House" became a
