Leptothrix discophora was in splender when I drove out to the Schoepfle Garden August 11. I didn’t see huge patches of it, but enough medium-size patches to satisfy me. The handiwork of L. discophora and other iron bacteria was also in evidence as great gushy trails down to the water. Along my walk I dallied over some rocks I considered first among equals. Number 9 is mudstone that held some kind of salts that left pits as they washed out in the river.
