Once beyond the bushwhacking zone, I note that some of the brush looks greener than the rest

This slightly verdant area indicates the presence of a little stream running through it, which seems to exude from under all those reeds.

Indeed, I hear a trickle of water amid the silence and locate it. There didn't seem to be much water on the ground around the spring that I identified, so it makes me wonder if perhaps there is a second spring further on under the reeds.
