From Lands End to Golden Gate: Discovering African American History on San Francisco’s Coast!

This account of a recent Outdoor Afro hike in the Golden Gate National Recreation Area describes how the histories of African Americans and their experiences in nature are part of the learning that takes place during Outdoor Afro’s adventures. Often these histories are left out of “official” interpretive materials.

Introduction to Issue Two

We commonly think of rivers as, for the most part, staying where they belong, in the river bed, occasionally coming out into the floodplain under fairly predictable conditions conducive to high water that we call “floods.” The writing in this issue of Open Rivers belies this notion of predictability, to a large degree.

Disturbing the Mississippi: The Language of Science, Engineering, and River Restoration

Around the world, from the U.K. to India, governments and NGOs are formulating plans and raising funds to restore river and floodplain habitat. Much of this restoration work is undertaken in the interest of minimizing or rolling back the effects of disturbances, such as hurricanes, erosion, and urban development, and shoring up resilience, a river’s natural ability to resist disturbances. However, the words used to explain river systems have come to explain what threatens them, and to explain what river restoration must therefore accomplish. Words shape deeds.

Maps, Geographies, and the Mississippi

U-Spatial provides support for spatial research. We make maps. And help colleagues at the University of Minnesota discover and analyze geospatial data. We collaborate with people in public health, nursing, business, history, anthropology, education, design, engineering, natural resources, and even dentistry.
