About this map

The settlement of Helena sits at a critical junction in Trinity County, where the steep terrain of the Trinity National Forest meets the winding Trinity River. This landscape is defined by its dramatic ridges and deep gulches, with high points such as Twin Sisters Mtn and Limestone Ridge looking down over the intricate drainage systems of the E Fork Big French Cr and the N Fork Trinity River. The network of forestry roads, including Hobo Gulch Rd and Manzanita Ridge Rd, provides the primary access through this heavily wooded territory.

Local landmarks such as Digger Pine Flat and Blacks Flat indicate small pockets of level ground amidst the vertical relief of Backbone Ridge and Treloar Ridge. The presence of numerous named water features like Treloar Cr and Miller Cr underscores the importance of watershed geography in this part of California, while features like Buck Spring and Mosquito Hollow point to the specific topography utilized by earlier travelers and foresters.
