What Formation Is This?

The Dry Dredgers welcomes member Dan Cooper as our featured program speaker this month. Dan’s program will be lessons in Cincinnatian stratigraphy as he explains how to determine the geologic Formation of your collecting site. This has always been a mystery to most of us and Dan will help clarify the characteristics of each Formation.

Dan Cooper is a member of the Dry Dredgers well known as an enthusiast and expert on trilobites both local and worldwide. He is also known for his generosity to the Dry Dredgers and museums. He commonly donates specimens and shares collecting sites. He was kind enough to host a special December field trip for us to Trilobites of America.

Dan started collecting in the early 1970's when his father showed him a beautiful Flexicalymene meeki found near Monroe, Ohio. Over the years he has collected close to 20,000 trilobites mostly from his property just east of Cincinnati. Dan has other trilobite collecting localities in Indiana, New York, Oklahoma and in the western United States.

Beginner's Class
by Greg Courtney 

TThe beginner's class will meet in Braunstein Hall, room 201 (the regular meeting room), February 28th. We will meet promptly at 7:15 PM and return at 8:00 PM. We'll walk next door with Dr. Carlton Brett who will give us a tour of some of the displays on the 5th floor of the Geology building. We will see and learn about Silurian and Devonian age fossils. We will also visit the student teaching labs and look at a project in progress on a new drill core of Cincinnatian to Silurian rocks drilled near Dayton. This is not a repeat of last month’s tour.

An “Extra” Day for a Special Indoor Field Trip
by Bob Bross

There’s an old joke: “How manymonths have 28 days?” The answer of course, is: “All of them.” [Insert drum roll here.]

Every four years, a February 29th shows up on the calendar; that extra day this year is a bonus for the Dry Dredgers, as we will be making a special visit to the Geier Collections and Research Center. Saturday, February 29th, at 1:00 PM. (Please note that this is an afternoon event, from 1:00 until 3:00 PM.)

For those not familiar with this facility, consider this: the Cincinnati Museum Center has a number of wonderful items on display; however, it is only a fraction of what is available. The majority of the material could simply be packed in a warehouse somewhere, but it would then be inaccessible to researchers. The Geier Center is the repository for a multitude of artifacts: pieces of Cincinnati and world history; art; unique zoological specimens; and of course, fossils. Everything is preserved in climate-controlled storage, and can be accessed by researchers and others to further overall knowledge.

For directions to the Geier Collections and Research Center, see the full bulletin sent out to dues-paying members via email, snail mail and the members-only website. If you are not a member, but would like to come on this special indoor field trip, email Bill Heimbrock at and he will set you up.

Weather Alert
by Jack Kallmeyer

It’s that time of year again where weather could be a factor for our meeting. If the University of Cincinnati is closed because of weather our meeting will be cancelled. If the weather is going to be exceptionably bad on our meeting night and we decide to cancel regardless of UC’s position, we will inform you by multiple methods: by email so check that before you venture out on a questionable weather night; we will post a cancellation notice on the home page of our website; we will also post a notice on the Channel 19 closings list. If you are at all in doubt of the road conditions don’t risk your safety trying to get to the meeting.
