Hyampom Valley serves as the focal point for this 2021 survey, where the Trinity Wild and Scenic River and Hayfork Creek meet. This remote corner of Trinity County is defined by the intersection of the Six Rivers National Forest and the Trinity National Forest, creating a landscape dominated by dramatic peaks like Underwood Mtn and Chaparral Mtn. The small settlement of Hyampom and its nearby Hyampom Airport are situated along the riverbanks, reachable by winding mountain routes such as Corral Bottom Rd. The map illustrates a high-elevation network of drainages, including Eltapom Cr and Olsen Cr, which feed the river system. Notable landmarks such as Salmon Rock and Rays Peak provide orientation within this densely forested and complex watershed.
