Greetings SatAM17 :

Reviewing the "Wyoming Land Anomalies " again, it is apparent that one of the primary drivers of the "area" in question is the higher resolution GE images available along that N-S corridor. Many of the landforms continue to be suggestive to me of being ejecta, but others - the "linear features" are not.

The "Dots close to a Water" point to the Tear Drop lake I have placemarked in the attached KMZ file. That lake is aligned towards the PZ Big Horn Basin Crater immediately to the NNW.

The randomly distributed "dots" remind me of "Mima Mounds " or "pimple mounds"

My educated guess is that some of the linear & equally-spaced "dots" are electric transmission towers and their bases.

The "Rectiliniar Features" and "More Strange Features" are all about 100 ft long, and may be trenches cut for minearal exploration exposures.

As for other oriented landforms in the Chaco Canyon area, I concur that these are irrigation features.

Please note that my earlier keyhole file only contained a very small sample of the aligned High Plains Playa Lakes I have identified in another BBS post, US Southwest Playas: oriented Carolina bays?. These lakes have never been discribed as man made, nor do they have any linear geometric characteristics, but are oval and tear-dropped shaped similar to the Carolina bays. They are universally aligned to a NNW, SSE axis.
