The first Midwest Regional Meeting of AGU was held September 25–27, 1975, at the Wisconsin Center on the University of Wisconsin campus, Madison, Wisconsin. About 175 registrants participated in the 272 day (Thursday–Saturday noon) program of 90 papers and four panel discussions. The meeting served it's purpose of bringing together geophysicists and geologists who either work on the regional geophysics of the midwest or who work at similar institutions within a one-day drive of each other. The smaller format of the meeting in comparison with the national meetings meant that only two or three sessions were occurring simultaneously, thus permitting (forcing?) participants to attend papers outside their specialties. Few people were in the halls during sessions. Indeed, the prevailing mood was that if one missed a paper, one would be left out of ensuing panel discussions.
