1988 Map of Trinity

About this map

Red Mountain Mine and the small settlement of Trinity stand as focal points for human activity in this remote high-country landscape during the late 1980s. Located within the Wenatchee National Forest, this area is defined by the steep drainage of the Chiwawa River and the towering heights of the Entiat Mountains. The map documents a transition in land use, showing the protected Glacier Peak Wilderness boundary as it interfaces with established recreation sites like Phelps Creek Campground and Alpine Meadows Campground. Notable geographic markers such as Phelps Ridge and Old Gib Mtn dominate the topography. This survey captures a specific era of forest management and mining interest before further environmental shifts altered the accessibility of these mountain drainages.
