I will help him set something up but thanks for the offer. I'm just trying to find an easy to use solution. I created myself a clean Gaia account (I already subscribe) and am starting to lean that way. The free account allows the Gaia base maps, the topo maps, and aerial maps, which is all he is looking for. Running Gaia on his laptop, he could do all his reconnaissance on the topos. Once he's decided where to explore, he could download the appropriate maps onto a tablet he can take out exploring.A tablet with Avenza maps (these are USGS digital paper scans). No routing, just a dot on a "paper" map, alots of free and historic maps along with all the parks and such.
Next is OnX where he just clicks "offline maps" and does it 10sq mile squares and it draws a green lined square on anything you already downloaded.
It can do topo, or a hybrid of topo overlaid on sat images (which is really nice to know if there is really water/green in that wash)
GAIA would be the next easiest to use as it will let you select a variety of map sources including historic maps
Best is if someone helps him download (only needed once) and gives him a run through. Depending on where in Utah he is I would be happy to meet up.
