We looked it up on the map, and unfortunately, it is too far for us to drive and be back in Salt Lake City by Saturday night for goodbyes to family and new granddaughter before heading back to Mobile, AL on a flight Sunday.
We went to the Moab area last week and did some collecting, including a nice grape jasper-agate nodule full of blue celestite Jeanette found. Mostly we were sightseeing. I wanted a specimen from the uranium mine but...
I'll do a more complete report when we slow up.
