Lower Toklat River Ranger Cabin No. 18

The Lower Toklat Ranger Cabin No. 18, also known as the Lower Toklat Patrol Cabin, is a log shelter in the National Park Service Rustic style in Denali National Park. The cabin is part of a network of shelters used by patrolling park rangers throughout the park. It is a standard design by the National Park Service Branch of Plans and Designs and was built in 1931. The cabin has twelve separate log dog kennels, also to a standard Park Service design.

Work began in the summer of 1931, with construction carried out by contracted carpenters, described as "two old Swedes". A ranger-built food cache and dog houses followed in 1933 and 1936.The design originated at Yellowstone National Park, adapted in this case with a somewhat larger size.
