1988 Map of Trinity

About this map

Trinity sits as a central point of human activity within this late-twentieth-century landscape, positioned near the confluence of Phelps Creek and the Chiwawa River. The map highlights a region transitioning from its mining history to a focus on recreation and wilderness preservation. Evidence of industrial roots is found at the Red Mountain Mine, located north of the settlement. Much of the surrounding area is defined by the high-elevation peaks of the Wenatchee National Forest, including Carne Mtn and Old Gib Mtn. The survey documents a network of managed outdoor spaces, including the Phelps Creek Campground, Alpine Meadows Campground, and Atkinson Flat Campground. These sites, along with the Glacier Peak Wilderness boundary, illustrate the late 1980s management of this mountain environment, where drainage systems like the Entiat River and Little Giant Creek carve through the steep terrain of Phelps Ridge.
