Spruced up the 'ol home office with a nice wall map (with Legend)!
Colorado Geologic Map... coated with heavy plastic so that I can use Dry-Erase markers.
As a fossil nerd, the info is very valuable. I'm still learning how to use it to my advantage in other areas of mineral exploration. Very nice to have it next to my computer!
(D&D... can we have a Fossil section in the forums? )
