The hanging bog which drains into the southwest corner of Silver Lake in Dickinson County, Iowa, offers an environment which is rich in both O2 and H2S. The bog consists of numerous small shallow pools, one to ten feet long, one-half foot to four feet wide, and usually two to six inches deep. (Map, fig. 1). Water from the bottom of these pools has a noticeable odor of hydrogen sulfide. The flora of this bog are being studied by Dr. W. A. Anderson of the botany department of the State University of Iowa.
