Correct, RTH was not set high enough for this mountain. I now have it set for 620', enough to clear the peak which is 596'.
I am not sure what the Peekaboo guy was doing. Since he had a blue helmet on I thought he must be a mountain biker, but there is no mountain bike trail up there and the hiking trail requires a lot of rock scrambling in places where a bike would have to be hand carried. Also, the backside where he was drops off vertically. I'm guessing he was doing some type of exercise, maybe squats. Weird for sure!
