Natural History and Supernatural History

In addition to the numerous fossil and mineral vendors, the Falls of the Ohio Fossil Fest was also attended by local organizations dedicated to natural history outreach and education. The Kentucky Paleontological Society had a particularly wonderful set of locally gathered fossils in display cases. I was impressed with the care taken to identify and prepare them. Fossil prep is one of those sweet spots where art and science meet, and it was clear that some strong TLC went into these.

KPS president Dan Phelps presided over one of the day's four presentations on local natural history, giving an informative, often humorous overview of Precambrian fossils. He also brought along an impressive collection of them, which people were pretty excited to get to examine up close. Unfortunately, my low-light photography skills are pretty rotten, so I don't have many good shots of this part of the day (save for the Australian stromatolite below). The KPS is providing a valuable service to the region; I was stunned to learn that Kentucky doesn't actually have a natural history museum. I talked to Phelps about this sad fact, and with a slight note of bitterness, he quipped that the state could only boast a "supernatural history museum."

The Future of Under Indiana

When I first posted about the festival on Monday, I wrote that there would be a weeklong series on it. As I thought about it more, I decided that going forward, it would be more appropriate not to fold those sort of posts into this blog. One of the takeaways from the festival was how much of a need there was for more of a web presence dedicated to Indiana natural history, especially something more 2.0. We need a flexible, dynamic way for people to share what they know and further educate themselves.

As a first step, I've begun another science blog. It's called Under Indiana, naturally, and I'll be doing all of my local interest writing there, unless some nutty farmer overturns everything we know about Indiana geology by finding a pterosaur on his land.

Feel free to follow me there, if reading about natural history of a smallish midwestern state gets your kettle boiling. There's not much there yet, and I probably won't be posting as much as I do here. But I'm as dedicated to making it readable, fun, and informative as I am here.

Under Indiana: Falls of the Ohio Fossil Fest

This is the first post in an ongoing series I'll be dedicating to the natural history of my home state of Indiana. I'll be calling it Under Indiana. Locals who remember the "Wander Indiana" jingle can feel free to get it lodged in their noggins.

This weekend, I attended the Fossil Fest at Indiana's Falls of the Ohio state park. It's located in Clarksville, right across the river from Louisville, and has hosted the festival for sixteen years. This was my first. I was quite impressed with the dedication to natural history here; along with the Indiana State Museum, it's one of the only places in Indiana dedicated to interpreting the state's deep past. Volunteers were there in abundance to explain the ecology, the history of exploration of the site, and especially the fossils.

The Outer Bank

This photo shows the park's claim to fame. At this site, the Ohio River has exposed a nice stretch of Devonian limestone dating to about 380 million years ago (with limited exposures of the older Silurian and younger Mississippian). It was a good year to pick as my first visit, I was told: the river is low right now, meaning that the Indiana shore, on the interior of the dam you see in the background of the photo, is easily reachable on foot.

The shore is divided into an inner bank, the Indiana shore proper, and the outer bank, which sits just under the dam. The outer bank is home to the best fossils, and that was the destination of the hike I joined early in the morning. About two dozen folks joined in, all from varying backgrounds and levels of knowledge. The hike was led by volunteers with the park's Naturalist at Heart program who were generous with their knowledge and their time. I also hung out with a party from Kent State University's geology department. It was great to hang back and listen to them discuss what we were seeing, and fun to offer a couple tentative interpretations of some of the features. I was thrilled that I wasn't laughed off the bedrock!

Outer Bed Hike

The hike had a wet start, as we had to ford a small part of the river and make our way across the dam.

Fossil Coral

Once we reached the outer bank, the group separated out as individual fossils demanded our attention or the viewfinders of our cameras. There were so much fossil coral that it was very easy to imagine the floor of the shallow tropical sea where they originally grew, so many ages ago.

I just noticed the spider in the photo above, a reminder that fossils aren't just baubles for human enjoyment, but are still part of their living surroundings.

Horn Coral Fossil

The most common fossils in this spot are the horn corals, so named because early American settlers mistook them for fossilized bison horns.

Fossil Bryozoan

Keen eyes could also spot the occasional bryozoan peering out from the limestone.

Stay tuned for more photos from the Fossil Fest and discussion of the event and the natural history of the area all this week.
