Colorado State introduced a new design in 1973.  The ram horns varied in width.  In 1973 they were both very thin and very thick.
This photo is from Game 1 vs Arizona.

This photo and the one following are in the same picture so you can see the thin horn and thick horn were used in the same game.

This photo is from Game 11 vs New Mexico (last game of the year) and shows a thicker horn.

1970-72
The base helmet was a plain yellow/gold helmet.
