I’m Mike Habeck, a retired environmental scientist, writer, photographer, and creator of websites about Indiana’s environment, Indiana historic architecture, and what may be the web's largest directory of U.S. environmental organizations. I dabble in other things as well.
EcoIndiana is a large and very incomplete information clearinghouse of sorts for Indiana's environment. The are hundreds of individual natural area profiles along with pages devoted to watersheds, ecoregions, events, organizations, and toxics.
A repository of over 1,000 images of old buildings located around the state. Many of these buildings are on the National Register of Historic Places, while others just struck me as old or cool. Many have at least some notations, like street address, year of construction, or bits of history.
This is probably one of the largest directories of U.S. environmental organizations on the web. Roughly 2,000 organizations appear, with brief descriptions of their missions.
