Welcome to the forum Libertyhead!
Have you thought about making a jaunt over to Teller County, around Cripple Creek and Victor? Plenty of old gold camps in that area but I am not sure of the legalities of detecting in the area.
p.s. I assume that by listing El Paso County, you are from the Colorado Springs area, correct? Have you ever been to the
ANA Museum on Casacde Ave?
