Once an agricultural and mining area, Jefferson County, Colorado now is a thriving suburban, business, industrial and residential community. It's a place where the great plains meet the Rocky Mountains - with some of the most magnificent scenery in the country, from rolling grasslands, craggy rock formations, natural foothills, rugged mountains and tumbling mountain streams.
