Squaw Creek Canyon – Bad Roads for RVs is located on U.S. Highway 95 south of Marsing. This road is a steep two-lane road. U.S. Highway 95 is also known as the I.O.N. Highway No. 456 ( I.O.N. stands for Idaho, Oregon, Nevada) The road descends part of the Little Squaw Creek Canyon and Squaw Creek Canyon. Eventually the road flattens out and one mile after the descent is the Idaho Port of Entry.
We have traveled this section of U. S. Highway 95 multiple times, both summer and winter including October 2018 southbound between Boise and Winnemucca. Just south of this grade we started having RV trouble which was not related to the road, but a story all by itself. Boise to Gardnerville
