My sister use to live in Aurora (Denver) and now lives in Parker, Co...does that count? LOL I love it there, just the altitude and my body don't work well together

Was able to make it to Pikes Peak, Contential Divide and even have a piece of the ROCKIES in my China Cabinet

....so yes, I own a PIECE OF THE ROCK

LOL
Hi Mary and Welcome. We are newbies too

We've only been detecting since April and having a blast!!!
You mentioned silver mines and such...my hubby recently found a web site about old mines and such in Virginia and recently ordered some books from them. It included maps of where all the gold mines and such are located. Very informative!!!! (Dept of Mines, Minerals and Energy -- Virginia)
Hubby and boys are going camping this week coming (that male bonding thing while I stay home (my choice) and throw everything in my house in the trash!!!)....and he has been mapping on todays maps, all the locations and found where he wants to camp and all. They are so excited. I told him not to come home without my BIG NUGGET!!!! heheheehee
I did locate a site for Colorado, if you would be interested or anyone else reading this post.

Happy Hunting and hope you have a blast in Colorado!!!.............Ann
