I was just sent this over email, and it's WAY too insane not to post.
This is a road gap near the sewage plant in Lethbridge that is apparently called "straight flush". To the best of my knowledge it had never been attempted, and from what I've been able to garner this guy is the first one to grow the stones for a run at it. Sizes kinda vary, but I've heard the gap is aroung 40 feet in height by almost 70 in length. Hard to tell exactly, but it's MASSIVE.
The landing is less than impressive though.....
