Well yeah, the scree field was only about what, 60-70deg incline?

These are 90+. :)

And, a scree field is *ALL* handholds. These have blank flat concrete in between them. I'll run up a scree slope all day long without fear of falling. If it starts to slide, just ride it out and make sure you're on the top of the wave. ;)

This is just a *wee* bit different.
