Thanks dredgernaut,
Perhaps the only way to know what that ravine has and doesn't have, is for someone to go in and find out. If anyone has been there and really investigated it . . . I guess they are not ready to discuss it here, or maybe might not be alive anymore.
After coming across the Waltz Map, and recognizing the location as this ravine, I was first excited and then that drifted to being bummed out about it. That map still has me flustered. What if all of a sudden one of you happen to see LDM map that you have always dismissed, but now. . . all of a sudden you REALLY see it, and it reveals your secret spot, beyond any doubt. . . . That is where I am at. Perplexed.
