The Top photo "478-8" Appears to be on the trestle located about 1.75 miles south of "carbon Junction". It's now about 1/2 mile West of what is now the Junction of US 160 and 550. Go to Google Earth and locate 37*13'04.30"N and 107*51'12.12"W. The Trestle still stands and is used to hold up pipelines. If you go to "street view" on "trestle Street" just west of the location you can clearly see the trestle.
Shots "478-9 and 10" are about 10.5 miles further South. The shot is looking West from what is now US 550, at the top of what is localy called "Bondad Hill" Google Earth to 37*04'33.10"N and 107*52'22.69"W. There is no street view to show this location.
