Unknown Slab

When walking to the Hideaway one day, I noticed that this line was newly scrubbed off. I hopped on it and found it to be a neat, little, slab boulder. Let me know if you know anything about it, such as who scrubbed it off.

I started standing with my left hand on the obvious, left-facing sidepull and my right hand on nothing in particular. Go up, encountering a thought provoking slab sequence with a somewhat big move right before the easy topout.

At the warm-up area, it is just left of a blunt, faint arete.

Crashpad(s), spotters optional.
