The Gateway Geyser has been on the blog a couple of times before (here and here). It is set back some distance behind the Arch and downtown overlook opened a couple of years ago in East. St. Louis, Illinois. I don't get over there much but it was a glorious morning yesterday and I decided to go shoot from the overlook. I finished close to noon, one of the thrice-daily eruptions of the geyser. It didn't go very high - the altitude of the plume is determined by the wind speed. When the air is still, the geyser reaches 633 feet / 192 meters, the height of the Arch.
At some point I turned around and shot in the other direction, as noted today on Downtown St. Louis 365.
