The Smithsonian Institute has just opened a new exhibit on soil. "Dig It! The Secrets of Soil" is open until 2010 and highlights a variety of issues and concerns about soils. It presents information in a variety of formats, which seems likely to reach a pretty wide age range.
We visited this past weekend and were duly impressed. One of the highlights was a mock-CSI episode in which the soil scientist wore an expensive pantsuit into a forested dig site and when the lead investigator over-dramatically donned his sunglasses after solving the mystery. Another cool exhibit included a monolith or profile of the state soil from each of the 50 states and a couple territories. Go Antigo! Great stuff.
