here are my guesses on soksal & munbawi. when you are climbing and you get above the tops of the trees you can see the resevoir. i tried to draw the "trail". it may be that soksal and munbawi are the next valley down (south) but i can't tell for sure.
also, could you post a picture of the area a little more east of the part marked halmaebawi and without the marking? at the base of halmaebawi is a little pond but im wondering if the marker is covering it up.
