Trinity Center and its small aviation field, Trinity Center Airport, anchor the northern reaches of this map where the waters of Trinity Lake fill the surrounding mountain canyons. The landscape is defined by the complex shoreline of the reservoir, which has submerged several former drainage systems and created features like the Irish Isles. Throughout the Shasta National Forest and Trinity National Forest, numerous named gulches like Tough Gus Gulch and Freethy Gulch descend from high ridges toward the lake. The terrain rises sharply from the water to prominent summits including Billys Peak and Jackass Peak. This survey provides a clear look at the region's recreation-oriented layout and its intricate network of creeks, such as Swift Cr and Rancheria Cr, that feed the main body of water.
