The Lower Cliff sits down and left from The Hive. Despite the fact that it's about 20-25 feet tall and over 100 feet long, it might be difficult to find until you're right on it.
The Lower Cliff has some potential for cool problems. There's a steep face/boulder on the left, a less steep wall in the middle, and the Smear Tactics boulder on the right. There are also a few boulders right below the cliff that might have potential.
