underlain by a strong fault zone of sheared felsic to intermediate metavolcanic rocks that is approximately wide. This fault zone, known as the Northeast Arm Deformation Zone, and the associated metavolcanic rocks are associated with the Temagami Greenstone Belt, an Archean greenstone belt characterized by felsic-mafic volcanic rocks. Lake Temagami and its surrounding lakes provide endless opportunities for canoe camping. There are over 2,000 km of interconnecting canoe routes. The region contains some of the largest remaining stands of old growth red and white pine forests in Ontario. History In 1834, the Hudson's Bay Company opened a fur trading post on the lake, which operated during the 19th century. The Forest Reserves Act of 1898 established the Temagami Forest Reserve on the shores and adjacent lands of the lake in 1901. It was created to reserve the forests for future logging by restricting settlement. In 1904 it was increased to . As a result of this reserve, the building of cottages and resorts was only permitted on the lake's islands. This restriction is still in force today. Lake Temagami is popular for cottage vacationing: the number of cottages on Lake Temagami are estimated between 630 and 746. In addition there are 9 youth camps, and 12 commercial lodges. Keewaydin Canoe Camp is based on Devil Island, in the shadow of Devil Mountain and across from Granny Bay in the northern section of the lake. Keeywaydin, founded in 1892, is one of several camps on Lake Temagami whose focus is on wilderness canoe trips using traditional equipment such as cedar and canvas canoes and wannigans. Since it began running trips in Ontario in 1902, it is the earliest known private business on Temagami besides for the HBC post on Bear Island. Camp Temagami, or A.L. Cochrane's Camp for boys, was founded in 1903 on an island in the South Arm of Lake Temagami. While Camp Temagami emphasized the importance of the wilderness canoe trip for shaping young men, the camp also developed a robust in-camp program that included athletics and life-guard training, as well as the study of the natural environment and Native American folklore. Camp Temagami offered canoe trips and in-camp activities for boys and young men until its closure in 1972. Camp Temagami was reopened in 2003, on the site of the old Wigwasati and Pays d’en Haut camps. Camp Wigwasati, on the southwest arm, began running canoe trips
