Here at the narrowing of the interstate you will have drove through the Portneuf Gap. The official Gateway to the Northwest
The narrow canyon of the Portneuf River through the Bannock Range between Inkom and Portneuf Narrows is the geographic key to the development of southeast Idaho and the city of Pocatello. It was this water-level route that became the Idaho Gold Road followed by stages and freighters from 1864 to 1878, and then the route of the Utah & Northern and the Oregon Short Line railways. This was not, however, the route followed by the Oregon Trail.
The canyon was probably cut by the ancestral Bear River, on the order of a million years ago, in response to the subsidence of the area of the Snake River Plain near Pocatello after passage of the ancestral Yellowstone Hot Spot.
The canyon follows a line of weakness along the east-west Portneuf Narrows tear fault that probably formed in Cretaceous time during folding of rocks of the Putnam thrust plate. This tear fault passes north of the Portneuf River at Portneuf Narrows and separates rocks of the Late Proterozoic Pocatello Formation to the north and underlying Chink's Peak, that are structurally overturned, from correlative strata on the south side of the fault that are right-side-up.
The rocks exposed between the west side of Portneuf Narrows and Inkom span about 250 million years of earth history, that is from Late Proterozoic to Upper Cambrian time (750 to 500 million years ago). They thus were deposited during the development of complex invertebrate life forms which appeared on earth between about 610 and 540 million years ago.
There is some complex geology in this area and not to far west from here is Scout Mountain’s Justice park recreation area and Mink Creek recreation area. All of this area offers up a good variety of stones and fossils for you rock hounds.
