The mysterious Anasazi Ski Tracks.
Nobody I know has any idea what these are or how they got there (let alone how old they are). They look even weirder in person.

@akkana fascinating! I wonder...

@akkana looks like someone dragged something up and over that many, many times. What's on the other side of it? Could it have been ropes rubbing?
Very cool!!

@akkana Clearly Anasazi kids sliding down the rock. I'll bet their parents yelled at them for wearing through moccasins...

@douglasvb On top, the mesa flattens out (I know it doesn't really look that way because there's a little hump at the top of the tracks getting in the way of seeing what's there) and there isn't really any place to attach a rope.
There are lots of incised trails in this area, worn to a depth of a foot or two by feet over hundreds of years. So it doesn't take much to wear the rock down; but the footpaths are all rounded and wide, nothing as sharp and well defined as these.

@akkana huh. And it's weird how the two drag paths converge.

@akkana Is it not simply the case that a rock which erodes more quickly is interspersed with a rock which erodes more slowly? The two minerals mixed well at high temperature, but separated as the rock cooled, forming lamellae. Or, if they're sedimentary, maybe the layers record a river changing course, etc.?

@alison It's hard for me to imagine such sharp, parallel, straight tracks forming from something like that. They're volcanic, tuff or maybe pumice.
