Which regions of the United States contain many Spanish place-names?

In the United States, Spanish place-names are most prevalent in regions that were historically settled and governed by Spain, specifically the southwestern, western, and southern parts of the country.1

The Spanish language has left a significant imprint on the geography of these areas. For example, in Colorado, the state’s name itself is derived from the Spanish word colorado, meaning "red" or "ruddy." Additionally, numerous cities, villages, mountain ranges, and peaks throughout the state bear Spanish names, and many major streams are referred to as ríos.2
