The first big thing you notice about northern Colorado is that it's a place where mountains meet the plains. Travel back out onto the plains a few miles to the east, turn around and look west, and you'll see the high heart of the Rocky Mountains - Longs Peak, Mt. Meeker, even Pikes Peak on a really clear day - but standing between you and those high peaks are the hogback ridges of the foothills.
Both in terms of ecology and human culture, these places where two different zones meet are unusally rich. Animals have thrived on this landscape for uncounted millennia, moving between plains and mountains, and humans have lived here for over 13,000 years. But with population surges and building booms along Colorado's Front Range in the last 20 years, fewer and fewer pockets of our natural and cultural histories can be found.
The stops on Tour 1 highlight some of the marvelous diversity, both in the natural and cultural worlds, along the foothills of northern Colorado. The oldest, Gateway, became a park over 100 years ago, while Red Mountain Open Space and Bobcat Ridge Natural Area have been protected in just the last several years. All represent our regional commitment to protecting our unique heritage.
