2011 Map of Haystack Mountain

About this map

The Portneuf River corridor dominates the eastern edge of this Idaho landscape, where the small settlement of Pebble and the railroad-adjacent Pebble Siding sit near the mouth of Smith Canyon. The terrain rises sharply to the west, culminating at Haystack Mountain, a prominent peak that separates the major drainage basins of the area. This 2011 survey captures a mix of modern infrastructure and deep historical routes, most notably the Old Oregon Trail Rd traversing the southern portion of the sheet. Numerous seasonal and perennial streams like West Bob Smith Creek and Robbers Roost Creek carve through deep canyons such as Reed Canyon and Bell Canyon, highlighting a complex hydrologic network that feeds into the Portneuf. Public access points like the Upper Portneuf Access Area indicate the river's ongoing importance for local recreation and water management.
