Now these took a lot longer to get than I had planned. I spent a good 3 - 4 hours working on all 8 areas. Don't have the exact mileage and so forth. Just a few field notes to pass along. The 4 areas on the McCaskill Quad are easily reached, but one.
Northernmost spot requires some tricky work to wiggle under a barbed-wire fence.
Andy's book mentions that they're by the RR tracks. Well, the railroad tracks have since been torn out. All of the spots do appear to be at the same elevation. The other 4 areas on the Nashville and Nathan Quads are a bit trickier. Some of the areas are in thick brush but most of them are in open fields where hand leveling can eliminate a lot of work.
