Colorado on the map
Broomfield, formed in 2001, is the newest and smallest county and carries a ring. Las Animas, on the New Mexico border, is the largest. Its neighbors, Wyoming, Nebraska, Kansas, Oklahoma, New Mexico and Utah, are drawn around it without numbers.
Denver and Broomfield are both a city and a county in one. Point this out before students look for a separate city.
