Sweet shot

I've always wanted to see penitente or sastrugi up close.

Re: Sweet shot

Hey, thanks! I've only ever seen them down in South America... don't know what the deal is on that. This was a little field at about 16K and they were melting so quickly that I bumped a few and knicked them over....

Re: wow!

My guess is that the snow starts to melt, with debris settling into the low spots. The debris then absorbs more warmth from the sun and the low spots melt even faster, leaving pinnacles behind.

On Cerro Bonete, on the descent after the summit, I wanted to hike over to a little sub-peak to the east. There was a narrow but tall penitente field in the way, and the fins were running perpendicular to my desired direction. They were so tall (about 2m) that I could not really step over them, and they prevented me from crossing!

About them being so common in only this part of the world, I suspect it is due to the climate (warmth and dryness) of this part of the Andes, which would facilitate melting, evaporation, and sublimation. I also could not help but notice the complete lack of trees at ANY elevation in this part of the Andes. This says strange things about the climate here, maybe that it is very dry, at least in parts of the year.

Excellent

Great work! I was unaware of penitente until seeing your photo... they remind me of Devil's Club, which is my arch-nemesis at lower elevations.

Re: Fanatastic

Appreciate it! I kind of wish I was back there myself...

How tall?

How tall are penitente commonly? They look like they'd be a complete pain to climb through!

Re: How tall?

The ones I've seen range from so tiny you could stomp them to almost three times my height. You're right... they definitely slow you down. And unfortunately, they're often right on the best route up.

Perfect!!!

It's all that I can say...

Re: Perfect!!!

Thanks! Have to admit that as I hiked up toward that field I was thinking, "damn, I bet I could get a great shot of Aconcagua from here."

Wow, and you were right.
Keep having these instincts.

Amazing shot!

And to answer the questions, penitente are formed in the same way as sun cups; the heat of the sun melts some of the snow, and the water trickles down to a low point. Eventually, the water melts out cups, which then refreeze. Repeated, intense cycles of this are what form penitente.

Re: Amazing shot!

Thanks Mark... I wonder why they're so much more common in the S. Hemisphere?

Re: Amazing shot!

I'm not sure about that. It seems strange, though. Maybe it has to do with snow conditions?
