309 S. Public Rd., Lafayette, CO 80026
Noticing coalmines in nearby areas, Mary searched for coal on her land. In 1884, coal was in fact found on the Miller ranch and the resulting Cannon Mine would prove to be the richest vein of coal in the entire Boulder Valley. In 1889, Mary platted a 158-acre town site named after her late husband. Over the next 40 years, Lafayette generated tons of coal and much labor strife. Tensions stopped for good when the last mine closed in 1957.
Today this town of nearly 25,000 people boasts an exemplary parks system and an attractive downtown featuring coffee shops and boutiques. Lafayette has carefully set aside greenbelts, bikeways, parks and open lands to preserve the natural atmosphere. The city lies north of Denver, and east of Boulder and the Rocky Mountains.
