In 1912-13 the student body built a stadium with bleachers where Stephens Hall is. It opened in 13-14. That was still in the Quad but became the permanent Football and baseball field location till Southwestern Stadium was built next to the swamp.
Add 1903 to the first field location. It moved slightly but overlapped the 1901 and 1902 fields. One corner started at Old Martin Hall which was closer to The Swamp than the current Martin Hall and the opposite corner was still on the side of the Swamp.
