[Rockhounds] Meteor crater: The impact crater that keeps on giving

Fun read, thanks.  Brings back memories from decades ago when I first
visited the crater and was able to hike around the rim, clockwise I
think.  It plays games with your mind because there's continuously this
big open pit to one side of you that seems to rotate as you "stand
still".

Years later I paid the entry fee again, and was able to circle the rim
again, but in the other direction.  It took about 1.5 hours again.

And years after that, passing through the area, I wanted to hike the rim
once more.  I talked with them at length, and the answer was a firm
"NO"...  "for insurance reasons."  You can't pay more, you can't sign a
waiver, you just can't do that any more!  Sad.

Oh well, on my first outing around the rim I picked up a small chunk of
weathered sandstone that I labeled, put visibly on a shelf, and still
enjoy seeing.  Even realizing full well that the rim has weathered down
something like 50' (if I recall right) from when the crater first
formed.  So this blob was violently involved, but probably not exposed
at the time.

Cheers,
