For a number of years, I have heard friends talking about going out to the Dugway Geode Beds
to dig for geodes.  We finally went on Monday, and it was
fun.  We left around 1:00pm and were there within two hours. 
It’s about 100 miles west of Provo out in the desert.  There is a
stretch of dirt road – the old Pony Express Route – that is 50.1 miles
of beautiful desert driving.  When you get to the right location,
you can see the southern tip of the Great Salt Flats.

I’m going to post a more official page with photos, GPS coordinates,
etc. to assist others with what I found.  The biggest thing that I
learned is that finding the Dugway Geode Beds is not that hard. 
Digging for the geodes is the hard work, and where to dig is the
key.  Finding geodes is based on your ability to find the ‘layer
of pink clay’ that covers the geodes.  We found a spot where
others had been digging, and I started from there.  Once I hit the
clay – two+ feet down – I started to find geodes.  I didn’t know
that I was supposed to keep digging through this clay … next time I
know better!
