Description Suggest change

Relatively few people have been to the area, so you will likely have the place to yourself if you decide to check it out. The wall gets sun for most of the day, but the largest portion of the wall is shaded by two large fir trees in the early afternoon. The rock here is mostly good quality limestone with sharp, bullet-proof sections, but also some loose flakes as well. The formation ranges in slabbiness, with a few bulges here and there. The top of the cliff has numerous debris strewn about so it would be smart to bring a brain bucket. The top also offers no easy access to anchors. Stick clipping is recommended for some routes. Use your best judgement and remember this area has not seen much traffic.

Getting There Suggest change

After crossing the log to the Bear Canyon sandstone area, go up and left until you see a small cairn and a trail heading north, away from the sandstone, along the drier part of the hillside. The trail cut off is approximately 50 feet below the Under the Sea Wall, just past and to the left of the stone steps someone was kind enough to build. The narrow side cut trail to the Boundary Line Fin is marked with cairns every 50-100 feet. After about 5-10 minutes of travel, the trees and underbrush start to thicken and the trail becomes slightly harder to follow, though there are markers here as well. The path loses about 100 feet of elevation as it takes you toward a small drainage. Another 5-10 minutes will see you to the small arch on the backside of the fin.

For directions to the initial log crossing and the Bear Canyon sandstone, see the main Bear Canyon page.
