At an August 1985 meeting in Prague, atmospheric scientist Pawan Bhartia presented this satellite-based image that revealed for the first time the size and magnitude of the Antarctic ozone hole. The discovery ultimately led to the 1987 Montreal Protocol, a landmark international treaty designed to phase out ozone-depleting substances. Yesterday, Sept. 16,2012, marked 25 years since the treaty was opened for signatures.
NASA satellites continue to provide clear snapshots of a generally stabilized Antarctic ozone hole as it cycles toward and away from its annual maximum depth by late September or early October.

decided to go check out this long forgotten community of Ozone .
Met some very frienldy people (the Judys)that told us all about the town ..when there was a town !...wished I would have taken notes ...
there were about 15 houses , a store and a school which was moved to Ammon and is still being used...he told us about the cemetery on the hill too..not many markers left in it ...just grass and tumbleweeds..
I took some pics of one of the last standing building there ..the barn...
we were told that people have been stealing the wood off it ..so it might not be standing much longer ! that's so sad..it was quite the barn ,very big !
