Monadnock's bare, isolated, and rocky summit gives people wide, clear views. The mountain is clear mostly because of fires set by early settlers. The first major fire in 1800 cleared trees the lower parts of the mountain to make pasture for animals. More fires and hurricane damaged the forest more. Between 1810 and 1820, local farmers thought that wolves were living in the forest and set the mountain on fire again. The fire burned hot and powerfully for weeks. It destroyed the topsoil and removed trees and plants mountain above .
