From April 29 to 30, 2025, Jongmin participated a field trip across the Driftless Area in Minnesota and Wisconsin, a region traditionally regarded as unglaciated but nonetheless influenced by past glacial processes. The field sites were organic farms, where soils have been studied by Azucena, Ph.D. student in Yoo Lab at UMN, to investigate soil characteristics and soil erosion vulnerability. The primary purpose of the field trip was to retrieve installed temperate sensors buried beneath soils on the organic farms. However, we discovered a deep, trench-like gully running across one of the fields.
