On the way to Lakeside in May 2008, I stopped in Puddle Valley to examine two mysterious
ground formations that I had seen on-line with WikiMapia (same imagery as for Google Earth). The
formations are about 200 yards (183m) west of the Puddle Valley Highway in north-central Utah;
they lie at the center of this WikiMapia aerial view.

The larger of the two formations, in the shape of a boomerang, turned out to be a dirt berm;
it is the beige-colored line extending leftward from my car's windshield. The square dark
area "inside it" was a fenced-off area that might have been protecting vegetation from
grazing livestock. The ground inside the curve of the berm sloped gently to the west
(toward the apex of the berm), and was riddled with evaporation cracks at its lowest point.
There were cattle hoof prints in and around the low point. My guess is that it is a
construction for the collection of water, probably a watering hole for livestock. If
anyone has a better explanation, I would love to hear it, as I am a city person and
do not understand the finer points of farming and ranching.

The smaller formation---a curved line arcing away from the edge of the road---is one
of several here (and elsewhere in Utah); it appeared to be a drainage ditch.
