1987 Map of Mossyrock

About this map

Mossyrock and the nearby settlement of Ajlune are central to this landscape shaped by the managed waters of the Cowlitz River. By the late 1980s, the geography here was defined by the massive reservoirs of Riffe Lake and Mayfield Lake, separated by the Mossyrock Dam Spillway. This industrial infrastructure stands alongside older rural markers, including a local Cem and the Swofford Valley to the southeast. To the north, the terrain rises into the Snoqualmie National Forest, where the Tilton River meanders toward the village of Bremer. The map reveals a transition from the agricultural and residential pockets near Harmony to the timber-covered slopes of Bremer Mountain, illustrating how hydroelectric development and forestry have layered over the original river valley communities.
