THESE ARE JUNIPER TREES --ROOTS HOLD THE SOIL AND SHEET EROSION REMOVES THE INTERMOUNDS OVER TIME CREATING THE MOUND APPEARANCE.

As for other circular features in this set of placemarks, they are entirely consistent with mima mounds, a common natural feature of prairies in the western US.
Methinks the original poster is too credulous by half...

So.. duck mounds, juniper trees, etc... Most of you feel these circles are completely natural?
There have been sightings of similar circles just north of Mt. Shasta at a rest stop that appear to be of an artificial origin. Please see: Mound Formations near Mt. Shasta The circular features appear almost identical in size to the circles in the Modoc National forest. There are reports of a sign at a rest stop nearby that concludes the circles are of ancient man made origins.
The rock art in the Modoc forest appears to show circular patterns that suggest these circles could be more than natural features, plus they are not far from the Mt. Shasta circles of unknown origin.

You never really truly know unless you go.

Try contacting USGS. They have several 800 numbers and the operators are very friendly and try to call you back if you have a question they can't answer. I have not seen sonar maps free to the public on the web yet. I primarily work with the free info on the web that has been declassified.
From what I have researched this NOAA map is the best topography data out there now. Someone please correct me and send me a good link if I'm wrong..

Not sure were those are although I live near there. In addition to Junper Trees and duck islands, There are some natural features that give that appearance in this part of the state. The high clay soils a prone to freezing and thawing and over time they develope a mound appearance with surface rock accumulating around the mound perimiter. There is a discussion of this in Ca bureau of mines publication on the geology of the Macdoel quadrangle 1949. Look approximately 4 miles SE of the intersection of the Tennant Rd. and Highway 97.

These Land Anomalies, are probably seismic test holes for oil & gas development within the region. The reason they are aligned on perfect north and west alignments (and occassionally northwest southeast) is due to geophysics being more easily read by technicians who analyze what is underneath the earth to see where pockets of oil and natural gas are located in the Wyoming Thrustbelt. If you notice in surrounding areas of Wyoming, oil and gas roads dot the landscape.

First of all, the satellite photo is so dark it's a strain to look at, but beyond that everything there is perfectly explainable without referring to anything exotic. The small dark dots that cover most of the area are vegetation, probably Great Basin Sage (Artemesia tridentata) in this area. The light evenly spaced dots are in all probability Prairie Dog burrows - see this post.. The larger oval feature looks like a dried up seasonal pond. The evenly spaced dash-shaped are likely from seismic surveys searching for natural gas. The longer trenches are also some sort of survey activity probably. And the "underlying pattern" is slightly rolling terrain. Nothing too mysterious.

A collection of 4 anomalous, linear areas off the coast of Cuba. The linear features are underwater and seem to be close to areas that may have sub-surface anomalies.
The anomalies also show up on NASA World Wind images. Cuba Underwater Linear Anomalies

Unfortunately many of the Land & Sea Anomalies collection have been obliterated with the switching to a new service provider TruEarth. Many of the markers in this collection and around the Cuba area are over low-resolution imagery now since the switch to the new service provider and I really hate that. My hope is they will get better resolution of the Bahamas in the future.
If you would like to see some of the Bahamas anomalies they have been documented at the SD website at this link.
We do appreciate the fact that Google Earth exists but it is a bit distressing when images disappear when we want more to be added, not taken away.

Thanks for your response.
The area in Wyoming goes for many miles, that's one reason why I did not suspect this was any type of scientific testing residue.
Hmmm...
