Lassen National Forest terrain dominates this 1980s landscape, characterized by complex drainage patterns and high ridges along the border of Shasta and Tehama counties. Significant elevations include Grays Peak and the prominent Blue Ridge, which overlooks a series of deep ravines like Snoqualmie Gulch and Blue Gulch. Small-scale human activity is represented by Groves and the seasonal Camp Forward, which sit near the upper reaches of South Fork Digger Creek.
