this sounds insane, i know. but unless i'm mistaken, that's exactly what's happening on mammut's site intro: http://www.mammut.ch/intro.asp
unless of course this is some funky white rock i'm unaware of
anyone know who this is or how it's possible? that anchor rig must be pretty intense

I'm no ice climber or slacker by any stretch, but couldn't you just pop in a few ice screws on each side? Either vertically or horizontally?

It's on a glacier - just build a solid deadman anchor by burying some stuff. even a folded sling or a glove as a deadman can handle bodyweight, so bigger stuff (ice pick, skis, snow anchors, your neighbor's tent poles) should offer nice anchor points.
Ice screws might be tricky, as the ice melts under constant pressure.

I've rigged a slackline with a deadman in gravel before, a small 2x4 minimally buried was more than enough for me to walk with, so if one were to bury say a 40L pack filled with snow, I think that such a feat as this is very possible.

That said, he's walking it in bare feet. I'm pretty sure that's what makes this extreme.

No problem. I've yet to rig a highline on a glacier, but one that I read of, they did mention having to re-rig the line a few times due to pressure melting. Just gotta build a solid anchor though, and other than the anchoring systems and devices used, it's almost the same as rock.

Here's what I HAVE done, on the surface of a frozen lagoon here in AK. Photos of me by Kelsey Gray (Prezwoodz).

I've seen one of those pictures before... They are at Gasherbrum II base camp in the Himalaya.

A tree, backed up to the concrete bridge on one side.
The other side was a steel spectators' platform which was anchored in the rock. That side was backed up to a telephone pole.

The anchors were built with spansets & shackles, and made redundant with a whole bunch of webbing. The line itself was a threaded top line, tensioned to 18%; a less tight single underneath; and an even less tight rope under that, all taped together (correct me if I'm wrong on any of that Dylan or Larry). It was all super bomber (just a bit too tight!). Larry and Dylan did an awesome job.

Yep, that sounds about right. and yes it was too tight.
