Paul, IIRC Joe said there were some fairly big monuments that still existed up there on the ridge...a la "The Monumented Trail Over The Ridge"...but that they disappeared at some point. The "Gene Reynolds view" was from a location that was over the ridge, and to the NE of the saddle and the "Helicopter view". Joe had found some sort of manganese deposit there. The location actually kind of matched up with the "Ruth Camp" location in Ely's book, and then later the area searched by Tracy Hawkins, Chuck Ribaudo et al when looking for the cave of gold bars. Which would've piqued Joe's interest

If I'm remembering all that correctly
Do you happen to have a copy of Tom K's booklet of maps that was sold at the museum back in the 1990's? I was wondering if "The Waltz Doodle" was in that booklet, and if there was a date indicating when it was published. As I remember it, the map booklet was just xeroxed pages stapled together between yellow card stock.
The reason I ask, is Helen was no Dutch Hunter...and the first book, "Curse" was pretty much just info provided by Bob and Tom K. So we can reasonably conclude that the vast majority of her material for that first book was supplied by Bob and Tom. That's just a guess, but it seems fairly obvious in her book that it's about Bob and Tom's decades long hunt for the mine and it makes sense that any material that she used probably came via Bob and Tom.
And as we know, Tom was a friend of the Martin's, and if anyone found anything in Herman's cabin after he passed, it was the Martin family. I don't recall seeing the Doodle in Tom's map booklet, which I think was published after but the same general timeframe as "Curse". So my question is if the Doodle isn't in Tom's map booklet, why not? Which could mean a lot of different things, but one possibility could be that Tom thought it was different than all the maps in the booklet? As in the map was close-hold, or known for certain it was not in public distro. Tom said he published the maps so suckers wouldn't have to spend money on them. If the Doodle isn't in there, perhaps he didn't expect anyone to have or sell that particular map.
