I've been fooling around with the MVUMs for this area, instead of doing what I am supposed to be doing (i.e., work). And I discovered that the individual pages are very difficult to navigate without the "Guide" page. But unfortunately, the Guide is almost empty of place names, so it is hard to get oriented.
So here are a couple of tips to help you get started:
Murphy Hot Springs (unmarked on the map) is on the border of the squares marked R9E and R10E, just north of the state line. (These squares are "ranges," I think, using the venerable "township and range" system of surveying.)
You can trace the road to Jarbidge from that point -- the road first angles nortwest, then southwest, and then due south after it crosses the state line.
On that map, the town of Jarbidge (also unmarked on that map!) is in the lower center of R58E, below the only intersection shown in R58E.
Then, looking at page 3 of the MVUM, the town of Jarbidge is at roughly 41 degrees, 52 minutes N, 115 degrees, 25 minutes W. Major coordinates are marked on the margins of the MVUM pages; it is fairly easy to interpolate the town's coordinates.
One would think that these maps would be more user friendly. I certainly found the Sawtooth area MVUMs to be much easier than the Jarbidge maps -- I guess the national forest cartographers don't use a uniform national system??
