Bold Solo on Ice
I found this old footage of Mark Twight soloing what I am pretty sure is Polar Circus. The soloing is pretty rad because many times it shows Twight coming loose on both hand and foot placements simultaneously while smashing brittle ice into big dinner plates. To say that he is a confident showman would be an understatement since he soloed Slipstream, which I consider to be the quintessential, hardman, ice (death potential) route.
The route description on Cold Thistle for Polar Circus is excellent. The route is not thaaaat scary because many of the steps reduce overall exposure significantly. My partner and I bailed at the point where John Lauchlan was likely swept to his death (great pics of this section). I cannot overstate the terror I faced crossing such a simple stupid snow slope that was completely loaded, sugary and fracturing with every step. My biggest fear was not crossing the slope. It was letting my partner down because I did not want to cross the slope. There I was practically sobbing because I was too afraid to commit to the unprotected section and too ashamed to admit that I was such a puss (no offense intended for the opposite sex) and a cry baby. I kept yelling down, "I don't know man, it is pretty sketch, I am afraid to go for it. It is too shitty. Maybe you should do it!!!" (like it was going to be any better for him) Sob, sob, and wipe away the welling tears. In the end, We trusted my judgement and we both went down, no questions asked and no shame for doing the (supposedly) right thing. But that is the nature of the avalanche, I guess. You never know if it could have, should have or would have let go with you on it. We will never know.

BD,
There is footage on Mark's video of several climbs including Polar Circus. You can say what ever about Mark and Randy but there is no doubt they knew how to climb ice very well by anyone's standards.
If you have ever seen snow come off the upper bowl while anywhere on Polar Circus crying like a baby is a pretty common reaction. Being below the Pencil or at the base of the final Tier and having a couple hundred tons of snow dumped in from above are rather intimate thrills I wouldn't want to repeat.
Having the travese pitch release while you are on it (roped or not) would likely be fatal. As it was for John. Althoguh he lived through the initial slide. Good on you for turning around if you thought the slope was bad.
I don't think Slipstream is any more dangerious than Polar Circus other than the descent (which is very dangerious)...just a longer walk in and more effort for only 6 short pitches of water fall ice. But no question the route's name is well deserved
There are a few historical pictures and notes of the 1st and 2nd ascents of Slipstream on another blog I work at when I have the notion. I didn't take a camera on the 2nd.
