Book excerpt: Rocky Mountain National Park: A History is more than just the story of Rocky Mountain in its brief tenure as a national park. Its scope includes the earliest traces of human activity in the region and outlines the major events of exploration, settlement, and exploitation. Origins of the national park ideas are followed into the recent decades of the Park's overwhelming popularity. It is a story of change, of mountains reflecting the tenor of the times. From being a hunting ground to becoming ranchland, from being a region of resorts to becoming a national park, this small segment of the Rocky Mountains displays a record of human activities that helps explain the present and may guide us toward the future.
