Columbine was scheduled to host the championship in 1966, but flooding of the course by the South Platte River caused a postponement of a year.

Firestone Country Club in Ohio, scheduled to host in 1967, swapped years with Columbine and was the site of the tournament in 1966.

The elevation of the course is over 5,300 feet (1,620 m) above sea level, additionally dry and fast conditions shortened its effective length.

Tommy Aaron carded a course record 65 in the second round to take a four-stroke lead,[6] but a 76 on Saturday dropped him two back and he fell out of contention on Sunday with a 78.

The 54-hole leader was Dan Sikes, the chairman of the tournament players committee,[7] who shot a final round 73 and finished a stroke out of the playoff, in a tie for third with Jack Nicklaus.
