— BACKGROUND — Gwen Kelly, a 3rd generation Coloradoan, wanted to share OUR CLUB HAS SPONSORED EVENTS the state’s rich history and heritage with others. Toward this FEATURING WELL-KNOWN EXPERTS end she organized the founding of The Colorado Heritage Club WHO EXPLORE OUR HERITAGE. SOME OF THEIR in January 2011 and has led it ever since. Over the first year PRESENTATIONS ARE SUMMARIZED HERE. the club produced events featuring professional speakers and entertainers open to all interested Anthem Ranchers. By popular demand these evening events soon became the main focus. Low price tickets ($1—$3) were sold to cover costs. High quality videos were often shown at “matinees” (free). Local town museums, libraries, and historical societies were valuable resources. An extensive club website was created, THE PAST, BOTH RECENT AND DISTANT, with active links to these information sources — accessible via OF ANTHEM RANCH & OUR NEIGHBORHOOD the club web page. In April of 2012 The Colorado History Center reopened in Denver and it also became a valuable COLORADO DINOSAURS ! resource, http://historycoloradocenter.org/ . WITH DR.

You are not the first persons here on the western edge of the Great Plains.

These ancient hunters too were COAL SEAM renewed by the majesty of the Front Range in the morning sun. In later times, Spanish armies explored the Great Plains intending to conquer and colonize the land, but never quite made it up to Anthem Ranch. Although they conquered the peoples of Central and South America the Spanish could not extend their rule northward from While Lafayette and Louisville were both initially settled Taos through the Apache and Comanche territory. The lands north of by farmers, once coal was discovered they quickly became the Arkansas River up to Anthem Ranch were primarily Arapaho. The coal mining towns.

After an 1880’s drought the families in the area banded Erie was also different in that it was isolated from together and dug ditches to carry water from the mountain streams in Lafayette and Louisville.
