Adopted in 1911. Statehood in 1876. The flag consists of three alternate stripes of equal width and at right angles to the staff, the two outer stripes to be blue of the same color as in the blue field of the national flag and the middle stripe to be white, the proportion of the flag being a width of two thirds of its length. At a distance from the staff end of the flag of one fifth of the total length of the flag there is a circular red C, of the same color as the red in the national flag of the United States. The diameter of the letter is two thirds of the width of the flag. The inner line of the opening of the letter C is three fourths of the width of its body or bar, and the outer line of the opening is double the length of the inner line thereof.
