From the Foreword:
The CGS 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 sold out, prompting a new edition. The text is taken directly from the original version with a few minor edits and updates. The maps were recreated using a digital elevation model (DEM) base to enhance detail and clarify topographic position.
