3700 Geowilliams (1984 UL2) is a main-belt asteroid discovered on October 23, 1984 by Shoemaker, C. and Shoemaker, E. at Palomar.

Named in honor of George E. Williams, exploration geologist with Broken Hill Proprietary Co., Ltd. at Adelaide, South Australia. Williams discovered the Lake Acraman impact structure of South Australia, the largest such feature found so far on the Australian continent. He also discovered rhythmically layered sedimentary deposits of Precambrian age that exhibit periods closely matching those of the modern solar cycle.
