I am trying to figure out where this is in relation to Anthrax Ripple. At first I thought it might be the bottom of the larger gully just right of A.R. which is used as descent from that route but comparing your photo to my overview photo of AR and the descent gully makes the descent gully look wider than the gully in your photo. Maybe your route was further right. Was there any ice higher up in the gully than the 60m that you climbed?
Don - if you read this, add your opinion. I know there are a bunch of gullies between the Mess Left and AR that sometimes have ice and sometimes don't.
