Those links show an approximate map and some campground but not enough to actually generate a route. There are quite a few similar maps on line but nothing I would care to use for hiking a sketchy trail. The last time I was there the trail was not very well maintained and there were a lot of other horse trails in the area.
The third link lets you download a gpx of the depicted trail, although I don't know if it is the trail you were talking about.
I posted those just to show you how easy it is to find maps and gpx files online. A little more intense search might produce more sources.
