From the foreword:
The Colorado Geological Survey is pleased to present a new, colorized version of Gold Panning and Placering in Colorado–How and Where by Ben H. Parker. The original and popular 1992 book has sold out prompting a new, digital version. The text is taken directly from the original version with just a few minor edits and updates. The maps were recreated using a digital elevation model (DEM) base to enhance detail and clarify topographic position.
