Haven' there been some much larger gas blow outs in Russia this past year -- on the scale of tens of meters/yards across with corresponding much deeper holes. Sink holes versus blowouts? that's a pretty wide response. Can't professionals agree on anything (that's a joke folks) Rodger Fry and Don Colton are also geologists. Rodger is on this board, I'd like to hear his input as well. ----- Original Message ----- From: "Brent Watson via Utah-Astronomy" <utah-astronomy@mailman.xmission.com> To: "Joe Bauman" <josephmbauman@yahoo.com>, utah-astronomy@mailman.xmission.com Sent: Thursday, November 13, 2014 11:23:32 AM Subject: Re: [Utah-astronomy] Remember the Bowling Ball? Part two Joe, there was no raised rim. So far there are two theories - one being a sink hole and the second being a gas burst. I have contacted two geologists to help solve the puzzle, one a PhD, ex-dean of geology and ex-president of the US Geological Society, the second works for an oil company. They both have similar but different viewpoints. On Thursday, November 13, 2014 11:06 AM, Joe Bauman <josephmbauman@yahoo.com> wrote: Does it have a raised rim? These are really interesting.

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
