The Rulison site is just south I-70. There is a marker there, but I believe the site is located on private property. There is currently a lot of gas field drilling in the area.
The Rio Blanco site is, I believe, in the Piceance Creek basin. Although I don't know just where.
I have a Bureau of Land Management topo map that covers from just east of Glenwood Springs to just west of Rifle, from the Colo. River north to just below Meeker. It's the "Glenwood Springs" map.
newracer is correct. Both of those set of coordinates are north of I-70. In fact, the ones for the Rulison site would place it at the base of the Roan Cliffs in the oil shale slides. That's completely counter to all the local accounts that place it in the semi forested mountainside south of the river and I-70. There's something wrong with those coordinates.
I live in Rifle. I was going to do a write up of this for my 10,000th post but couldn't find any online archives from the local newspapers covering the projects. I can check out the library Tuesday, they're closed on Monday, see what I can find there.
What a strange, messed up week this has been. I forgot this was Friday. I'll see if I can make time to hit the library tomorrow.
