Pac-Man, that was one of my early solves. I thought I was going to have a heart attack when I found the Savery cabin and Putt Creek just below it! I had Slater as TEIEDN.. s’later! Take a look on GE on one of the creeks on the E side of Slater. That’s some lovely earth art. Never got there to check it all out in person, though.
And the YouTube video of that guy going over the falls in his kayak! Whoa.
