 As the 19th century progressed, fewer pines were left and more hemlocks and hardwoods were cut and processed locally.By 1810 there were 11 sawmills in the Pine Creek watershed, and by 1840 there were 145, despite a flood in 1832 which wiped out nearly all the mills along the creek.Selective harvesting of pines was replaced by clearcutting of all lumber in a tract.
