Good to see you back (out West?)
was wondering too. enjoy CO. Fossil Beds were very interesting. Make sure you do the trail where the fossilized trees are visible. Also, if you have time, the Mollie Kathleen gold mine tour in Cripple Creek is pretty cool.
yes, those huge fossilized trunks were an audible WOW. still in CO, Westcliffe by the amazing Crestone Sangre de Christo mountain group
