2017 Map of Sedgwick Peak

About this map

Lava Hot Springs occupies the northwestern corner of this study, positioned where the Portneuf River cuts through high mountain terrain. The landscape is dominated by the massive summits of the Portneuf Range and the Fish Creek Range, reaching its highest point at Sedgwick Peak in the southern reaches. A notable hydrologic feature is the Columbia River Great Basin Divide, which traverses the eastern slopes, separating the waters that flow toward the Pacific from those that remain in the interior basin. The map detail reflects a transition from the river valley into the high backcountry, where landmarks like Baldy Mtn and Buckskin Mtn overlook a complex network of seasonal drainages including Whiterock Cr and Dempsey Cr. This era shows significant recreational and local access via named routes such as the Wyoming Trl and Panamint Trl, which navigate the steep ascents between the peaks and the Fish Creek Basin.
