geoglyphs
Yuma BLM I noticed a pair of mysterious fences near the road while traveling back from one of my hikes. I stopped to read the sign of the nearest, which provided an explanation, and have returned today to actually see what they encompass. That most ephemeral and uncertain bit of ancient art: the geoglyph. And past the sign, narrow and long within the fence boundaries, is the preserved geoglyph. I rather suspect that without the sign, the fence would have been cut by now. As advertised, there are lines where the rocks have been removed from the generally flat and rock strewn surface of the plain. The first geoglyph from end to end.
