After my all day excursion to the Kentucky side of the fossil beds…my next visit to the park was a relatively short one. I had a few hours to work with and decided to check out the riverbank on the Indiana side. It has been very dry of late and I heard on the radio that farmers have begun revising their optimism about this year’s corn crop. Once again, we have had a season that seems atypical in a few respects. Most notably, our summer has been a cool one. No temperatures in the high 90 or 100 degree range…that would be about 35 to 38 degrees on the Celsius scale. Climatologists point to the cold Arctic air that came sweeping down from Canada during July as the reason our summer was not as hot. People around here aren’t complaining about that, but after last year’s polar vortex winter… folks are wondering if that bodes well for this year’s fall and winter?
In addition to the coolness, it’s also been dry of late. Seems that we haven’t had a significant rain storm to speak of in weeks and the river continues to recede. New pools are formed stranding fish in them and many creatures take advantage of this bounty. Walking along the cracked riverbank I find evidence of this.
I soon came across dead fish left behind in the wake of weekend fishermen. In this picture, an armored and toothy Longnose Gar (Lepisosteus osseus) lies side by side with an equally interesting fish that is rarely found here. With its thick body, white caudil fins, and unique pectoral fins…I identify this smaller fish. It’s more commonly called a Bull Gill, but science also recognizes it as (Taurus opercula). I wonder if there are any other specimens hiding in the deeper pools around here? To find out, I gather waste monofilament line found all along the riverbank along with a found lead-headed jig and before too long I have improvised a hand line for fishing.
After some trial and error, I succeeded in catching a Bull Gill by bumping my jig along the bottom of a wide, but shallow pool. The fish was well hooked and after a short struggle I was able to bring him up for a better look.
I hurriedly take as many photographs as I can. My intention is to release this fish back into the water after I document its presence here at the Falls of the Ohio. As you can see, this fish contrasts greatly with the dead gar we saw earlier. The gar is in fact a more ancient and primitive fish that relies on its hard armor for protection. The gar is mostly a surface fish mimicking a floating piece of wood while it stealthily seeks out smaller fish to ambush. The gar’s strategy has been so successful that it has changed little after millions of years. The Bull Gill evolved much later and lacks prominent scales on its more compact body. It too, however has evolved a unique method of feeding.
The Bull Gill gets its name from its powerfully muscled head. Just below and behind its gill covers, the unique pectoral fins have evolved so that this fish can support itself on the bottom of a swiftly moving stream or river. I was able to demonstrate this with my specimen. I placed my fish upon the rocks by the riverbank and it was able to support its body off the rocky surface using its strong and rigid fins. In the water, the Bull Gill secures itself on the rocky bottom with its stiff pectoral fins and with its head facing upriver. The Bull Gill is a predatory bottom feeder. As prey fish swim by, the Bull Gill with a quick burst is able to capture its food and swallows them head first before returning to its spot on the river bottom. I had this fish out of water for just a couple of minutes before releasing it safely back into the Ohio River. I had to say that I enjoyed encountering a creature you don’t see every day. It’s presence here is a good sign since the Bull Gill needs good quality water to thrive. I gathered up my collecting bag and walking stick and decided to check out my stash of Styrofoam under the willows.
The willow trees are up the riverbank and the leaves are beginning to yellow more noticeably. Along the way you pass by a couple of courses of deposited driftwood. I love the silvery color of this wood which is due to exposure to the sun and elements. I had a great surprise in store for me once I ducked under the cover of the trees. For many years I have known that White-tail Deer are present in the park because their tracks are all over the place. These ghost deer are fairly close to a populated area and extremely wary of people. They must move around the park in the middle of the night or really early in the morning to avoid detection.
As I moved near my spot, I spooked a doe and her late season fawn. I could still make out the spotted pattern on the fawn. They were bedded down near a large log that floated into the park last year. I first saw the doe which rose and ran off upon sighting me. The fawn then stood up and followed after its mom. I was unable to take a photograph because this sequence happened in just seconds. I then followed to see if a second glimpse was possible and I even doubled back to this spot should the deer attempt the same maneuver. Unfortunately, I didn’t get another look at them, but since they are near my outdoor studio, I will be sure to check for them next time.
It had been many weeks since I last visited my larder of river-gleaned materials. I could tell that people had been through here, but there is obviously nothing of value. I mean what could one do with water-tumbled polystyrene and sticks? If the river doesn’t rise anytime soon, I will come back and make something from this odd deposit. My next post, however, will come from the Kentucky side of the fossil beds. After this adventure, I returned with my river-polished coal and explored a few more areas around Goose Island and the hydroelectric plant. I think I made some compelling images that speak of a sense for place and I look forward to sharing them with you.
