2022 Map of Trinity Dam

USGS Topo · Published 2022

About this map

Trinity Lake dominates the upper half of this modern topographical survey, reaching its long fingers into the many gulches and canyons of the Trinity National Forest. The map documents a landscape defined by water and altitude, where the submerged terrain of the Papoose Arm and Ridgeville Islands contrasts with the surrounding mountain ridges. For genealogists and local historians, the northern portion of the map preserves the location of Ridgeville and the Ridgeville Cem, alongside several named flats such as Hayward Flat and Chicken Flat.
