It seems that Cochran road and Whitlow Ranch road are about the only roads that go all the way up to the Gila River. Whitlow Ranch road goes up to where all the water is taken from the Gila River and put in a canal. I didn't make it to the end of the road, though, so I couldn't see that.
I uploaded the full size panoramas to my web album this time, instead of all the individual pictures. If you zoom all the way in and then wait a few seconds, you should be able to zoom in a lot more. Click below to see all of the pictures.
