This is the second route in the second cluster of routes in the Corridor. Moving through the first 25 feet is the crux, though the route is fairly sustained. Fun pitch.
me·co·ni·um: noun-a dark greenish mass that accumulates in the bowel during fetal life and is discharged shortly after birth. (http://www.merriam-webster.com/) I was hoping for something a bit more compelling. Pretty gross! As for the "23" designation, I don't know. Fairly interesting route, though.
