Did this some years ago and had a horrific time in soft snow at the "corner". Conditions there (a bit) better this time. All the real fun in the ice of the first pitch or so of course.

First two pitches excellent sport with good ice, direct line up 2nd pitch offers sections of vertical ice, better to do right fork variation for the finish rather than easy gully at top of left fork. Great day out

led first pitch. Then went up the chimney to the right which had a desparate thrutchy couple of moves to get over the chockstone. Bomber placements all the way and great exit

After backing off Giant's Head Chimney (Scott deciding 75 degree mush a little unsafe!) followed a party of 3 up Parallel A. 2 decent ice / neve pitches. Led 1,3,5. 5 hours climb topping out in the dark at 18:00. Enjoyable first day out with Scott.

Good ice condition on the bottom and middle section of the gully. Snow on the last pitch well unconsolidated. It was fantastic climb.

Fantastic ice with 1st time placements! Wee bit hollow at the narrowing on 1st pitch but only for a couple of moves.

Felt quite easy. Chris got to lead the best bits (1st and 2nd last pitches). Some bits were unconsolidated with poor protection, other bits had good ice. Took us just over 4hrs.

Soloing up it. Found a helmet tumbling down. Then, an Alien ice axe. It was Richard's. Snow and ice was rotten. Not that pleasant. Cloud rolled in the afternoon but cleared by late afternoon. Nice view.

the ice was a bit thin and rotten in places which made belaying interesting with tv sized blocks winging past!

The route was not fuly formed. The first 20-ish metres was very thin and Tech. 4. The party behind us appeared to have a leader fall, we noticed they were in difficulty at the base of the route when we were on the third pitch. the casualty was moving so hopefuly it was not too serious (found out later the leader had broken his leg in two places). A chopper took them away. The first pitch was serious and by the time Joe had climbed it there probably was not much of it left. The third pitch was a 65m grade II snow romp.There was a steep ice section at the end of the fourth pitch which Joe led. Thankfully the cornice was a doddle but we had come to do Polyphemus so we had a rack of rock pro and some screws - no snow protection. Not clever. Polyphemus was not in condition at all; more black than white. The overall grade for Parallel A in this condition was probably IV,4.

Seems to need a lot of icing to be at its best. We ignored the SMC guide's advice to: "go for gullies when icing is good, go for buttreses when there's powder" and paid the price, finding this route pretty hard going at times. Bad weather moved in at around pitch 4 (the traverse left out of the gully), leaving Shaw waist deep in spindrift when he finally left the stance!
Peter Metcalfe - AltLd - 09/Apr/06 with Shaw Brown

First pitch a bit unconsolidated but enough good stuff to be OK. The guide recommends to avoid the chimney on the third pitch but we found it good. Spindrift city when the wind picks up, lucky for us that it waited until we were near the top.

Excellent first pitch. Tried right fork alternative, but out of condition. Eventually aborted, but then got stuck behind a very slow team. Dark by the time we got to the top. Mates on another route had got tired of waiting and gone to pub. They had a map. We didn't. After a couple of hours decided we'd have to spend the night out. Chris got his full 8 hours, I shivered. Finally got to sleep around 5.00am. Woken half an hour later by snow falling on survival bag. For first time started to get worried. More shivering till dawn revealed we'd bivvied about 500m from the track! Had to poke Chris with ice axe to stop him having Sunday morning lie-in. Greeted on walk out by land rover full of big blokes. Turned out mates had called out MRT! Got in very sheepishly for lift back to car. A proper mini epic. (Led Ps 1,3,5)
