In fact, this task is quite easy, it just requires a little thinking. There are three US States that begin with the letter C. They are:

  • California (CA) - Of course, California was the first state that came to your mind, as it is one of the most popular states in the country. A note from history: although California was sighted by Spanish navigator Juan Rodríguez Cabrillo in 1542, its first Spanish mission was not established until 1769.
  • Colorado (CO) - First visited by Spanish explorers in the 1500s, the territory was claimed for Spain by Juan de Ulibarri in 1706.
  • Connecticut (CT) -The Dutch navigator, Adriaen Block, was the first European of record to explore the area, sailing up the Connecticut River in 1614.
