Steamboat Springs The Colorado State University Cooperative Extension in Routt and Moffat counties will unveil a book tonight that depicts how area rivers and ranges have changed in the past 100 years.
The offices will unveil the book "Rivers, Range & Change" during a 5 p.m. gathering at the Depot Art Center in Steamboat Springs.
The book opening is set to last two hours. Appetizers and cocktails will be provided.
The purpose of the publication is to show a pictorial reference of the landscape changes in Northwest Colorado over the past century.
The limited-edition book took three years to compile by the extension offices and Neelan Resources.
To compile the book, photographs were gathered from museums in Routt and Moffat counties, the U.S. Forest Service and Bureau of Land Management.
"This was a unique project," said C.J. Mucklow, director of the Routt County Extension Office. "This book shows people how things have changed."
The 125-page book features 35 sets of photographs.
Organizers of the book were able to gather 35 pictures shot between 1910 and 1920 of rivers, rock formations and mountains within the two counties.
These pictures are then compared with current photographs taken of the same spots.
"There have been some remarkable changes in the rivers," Mucklow said. "But there has not been much change to the ranges of Northwest Colorado."
The project was funded by a $7,000 grant from CSU. Close to 750 books were ordered, but only 700 will be sold.
The book can be purchased tonight for $25. The book will also be available at the Routt County Cooperative Extension Office.
