Mulch rings in the Blue Ponds Canal area. Shown east at N 32.78831 W 109.76683. A large collection of dozens of mulch rings appears to be in association north of the Blue Ponds area of the combined Lower Frye Complex and Freeman Canals. These are single layered rock rings sometimes incorrectly called "cairns".  These rock groupings presumably reduced rainfall evaporation. This is the largest of several known occurances. A northern grid lies nearby. Nearest rough 4WD track is at N 32.78844 W 109.76700. Click to expand the image. Possible field notes here.
