1989 Map of Porcupine Lake
USGS Topo · Published 1989About this map
Targhee National Forest dominates this high-country landscape, where the Falls River carves a path through the southern reaches of the Targhee Ridge. In the late 1980s, this area functioned as a vital water management corridor, evidenced by the Marysville Canal and Yellowstone Canal running parallel to the river. The presence of a Gaging Sta near the western edge underscores the importance of monitoring these mountain flows for downstream irrigation and use.
