Ah, the luscious green forest of the Eldred Valley. This boulder happens to no longer be covered in moist green moss - and actually isn't technically in the forest at all anymore. The top half of the B Branch area has been exposed to the elements ever since the power lines went through, which keeps them moss free and super clean (to look on the positive side of a strip of forest being taken out of the valley).
Here we we see Emma spotting Angus on what was then an un-named problem, likely a V1. Since then, it has taken on the name Log Jam, from the pile of discarded logs clear cutting left behind - with just enough space to put a crash pad on.
