The Southwestern corner of Wyoming survey benchmark. This is the state boundary between Wyoming and Utah. The road is drivable in any vehicle all the way to the monument. We took highway 150 south from I-80 intersection for 18.8 miles out of Evanston, Wyoming to county road 150. The we went west for 7.8 miles on county road 150 which is also called Chalk Creek Rd. The we turned south at the intersection of Chalk Creek Road and went another 3.1 miles to a Y intersection. Chalk Creek Road keeps going and I can’t find the name of the other road that we turned left onto and went .5 miles to the monument. It’s 30.2 miles south of Evanston, Wyoming by road.
