RAGBRAI (the Register’s Annual Great Bicycle Ride Across Iowa) is an annual seven-day bicycle ride across the state of Iowa. This is the ride’s 44th year, and it is the oldest, largest, and longest bicycle touring event in the world.
Continuing the tradition, the Iowa Geological Survey, with support from the Iowa Limestone Producers Association, has created a series of informational brochures to help the RAGBRAI participants learn about Iowa’s geological, cultural, and natural characteristics as they ride across the state. The content was developed by staff from the Iowa Geological Survey, U.S. Geological Survey, and the Iowa Department of Natural Resources.
