This area has always made me curious. My atlas shows an area in Wyoming where the Continental Divide splits and then rejoins, forming a loop. It is labeled Great Divide Basin.
Question 1: John - how did you deal with this? Did you list the peaks on both halves of the circle?
Question 2: Can someone justify drawing the CD lines this way? My thought is that if you started filling the basin with water, it would eventually start overflowing on one side or the other, and you would know which half of the loop is the true divide. Or, is it that one of the 2 junction points are lower than anywhere else along the loop? In that case, whenever the water level reached the lower junction point, it would start spilling out into both drainages at the same time.
