Does it have a raised rim? These are really interesting. Could it involve puddles and ice? ------------------------------ On Thu, Nov 13, 2014 9:11 AM MST Brent Watson via Utah-Astronomy wrote:
A geologist friend in Idaho suggests these craters may be gas blowouts. She surmises that the is a concentration of organic material beneath this particular spot that produces gases including methane. When the pressure gets high enough it erupts to the surface leaving these pock marks.

Yesterday I went to the "crater" site to get an exact location. Chris, my son, went with me. We landed on the road and walked to the site. It looks like these holes in the ground are actually sink holes. Why they are concentrated in this one location that is maybe 1/4 mile in diameter I don't know. Perhaps a geologist can shed some light on why only here. Here are a couple of images from our little jaunt.

If nothing else, it was a lot of fun to go visit these "craters". I had a great time and so did Chris. Besides, it was a great excuse to get the airplane out of the hangar and convert some 100LL aviation fuel into fun. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy
