Good one Jack,
We started a thread for these "Rock Talk" quarterly newsletters about 4 years ago I think and there is a whole list for everyone to pick from of different topics for Colorado's geology. Here is the link for the list of all past PDF files/titles at the
Colorado Geolical Survey website.
They are all PDF files and great information for referencing too.
The one Jack posted above is the "Colorado Gold" issue from April of 03'.
Happy readin' everyone, learnin' is such fun!!
