Piles incorporating wire

A couple of examples. These seem to illustrate a point made by Mavor and Dix in Manitou that every day "junk" might have been used for offerings during Native American ceremonies.
Here is a rock pile incorporating a coil of barbed wire like a "wreath". Tim Fohl found this in Townsend.

Here, a tangle of straight wire sits on top of the pile and collects debris.I found this one in Bolton in the same conservation land as the broken plow tip pile.
