Surficial Geology of Wisconsin
This raster is a highly detailed map of geologic materials at the surface (delineations made from maps at 1:24,000 to 1:12,000 scale). The smaller extent maps were merged together by USDA-NRCS to produce the gSSURGO spatial database, covering the entire state of Wisconsin at a 10m resolution. The gSSURGO map was then interpreted by Iowa …Continue reading “Surficial Geology of Wisconsin”

What is Colluvium? An Interactive Poster Seeking a Common Definition to Improve International Communication (2015 SSSA Conference)
UPDATE: This poster was a test run for a survey asking the audience for their perspectives on how to differentiate colluvium and alluvium. That has now evolved into an online survey that you can now take. Respondents have told us that taking the survey was fun and thought-provoking. Please add your perspective by completing the …Continue reading “What is Colluvium? An Interactive Poster Seeking a Common Definition to Improve International Communication (2015 SSSA Conference)”
