About this map

Timothy Meadows Reservoir serves as a central landmark in this 1950s survey of the Clackamas and Wasco county borderlands. The landscape is dominated by the drainage basins of the Salmon River and the Clackamas River, where the terrain transitions from the high elevations of Mt Mitchell and Salmon Butte down to the Big Bottom river flats. This era shows the developed recreation network within the Mt Hood National Forest, featuring a concentration of sites such as Hood View Campground and Meditation Point Campground along the reservoir's edge.

Evidence of early mountain transit and utility infrastructure is preserved through the Oregon Skyline Trail and a prominent pipeline corridor cutting through the northern reaches near Lake Harriet. The map also captures several fire-lookout points and remote outposts, including the Pot Cr Cabin and the Sherar Burn area, providing a record of mid-century forest management and wilderness access before more modern road networks reached these heights.
