The bottom of this pillar was sporting a 6" diameter connection to the base, but I was unsure of how well it was bonded to the lip. To protect this climb, I clipped the second bolt on a nearby mixed climb then down-climbed back to the icy ledge. I then climbed up the backside of the pillar, placing no gear to drag me down the slope/over the next roof if it decided to collapse. After examining the pillar's bond to the lip of the roof (and being somewhat satisfied that it wasn't going anywhere), I fired in a screw, moved around to the far side, then continued up the wet face to the ledge above. I can't recall a time when I've been as scared, or exhilarated!
Too, one can see an ice-encrusted fixed line, which may be ascended if the pillar is not in (personally, I felt it was there for the sole purpose of creating a seed for the pillar to form around, but I may have been mistaken). Alternately, P7 may be bypassed by hiking east along the ledge, up a short 5.5 chimney 250' below the upper tram deck, then traversing back west to the next section of ice.
