Jamey - I didn't follow the left hand side up all the way. There very well could be a small falls somewhere up near the top. I basically went up between the two, but when I came back down, I did choose to scramble directly down the left stream bed because it was easier for a couple hundred feet or so than the muddy/snowy muck of the hillside deer trail. However, since this tributary isn't even on the map, it must be simply a seasonal stream - so even if there is a waterfall right now, it may not be there come summer. Its worth checking out though! Use caution if you do head up that streambed though as there are a lot of places where mud and rocks could pin you if a small slide occurs. For the most part traversing above the bank would be the safest in most conditions. Have fun and be safe on your trip!
