About this map

The North Fork Feather River carves a deep path through this 1970s landscape, serving as a corridor for both utility and transport. The Western Pacific railroad winds along the canyon walls, marked by engineering feats like the Arch Rock Tunnel and several numbered bores such as Tunnel No. 9 and Tunnel No. 11. Industrial activity is centered on hydroelectric infrastructure, including the Poe Dam, the Substation Cresta Powerhouse, and the associated Penstock and Surge Chamber near Mayaro.
