Join geologists Tyler Norris and Molly E. Hunt for a trip back in time to the Ice Age. After a short talk about the local glacial geology, participants will be led on the ADA-accessible boardwalk through one of Ohio’s premier natural areas.

Attendees will learn how the Ice Age shaped the area's landscape, leading to the formation of the bog. Ice Age plants and animals will be discussed as well.

Hikers are encouraged to wear sturdy hiking boots and/or waterproof shoes, bring hiking/walking sticks, and have plenty of water, snacks, sunscreen, and bug spray.

The event is free and recommended for ages 5 and up.

Calling all Earth Science explorers: Join the Ohio Department of Natural Resources, Division of Geological Survey for Ohio Geology Discovery Day!!

This event is free and perfect for learners of all ages who are excited about rocks, minerals, fossils and more. During the open house hours of 10:00 am–2:00 pm, visitors can engage in hands-on learning activities throughout the H. R. Collins Laboratory and Core Repository at Alum Creek State Park.

Activity stations will feature representatives from the ODNR Division of Geological Survey, ODNR Division of Natural Areas and Preserves, H2Ohio, Boonshoft Museum of Discovery, The Ohio State University School of Earth Sciences, Franklin Soil and Water Conservation District, Ohio Aggregates and Industrial Minerals Association, Ohio Natural Energy Institute, and The Ohio State University Byrd Polar and Climate Center.

In addition to the activity stations, visitors can grab lunch at the 614 Fully Loaded food truck and enjoy the picnic area beside the laboratory.

You will not leave empty handed, with plenty of available giveaways, maps, and educational publications available.

So, load up the kids, grab your friends, and join us for this outstanding program!

Join ODNR paleontologist Mark Peter, geologist Brittany Parrick, and Orton Geological Museum Curator Dale Gnidovec for a guided tour of the vast array of fossils that decorate the building stones of Ohio's capitol. This free, biannual event is a favorite for anyone interested in Ohio's cultural and natural history. Offered twice, participants can attend either tour at their preferred time.

Participants should meet in the Worthington Classroom on the ground floor and will receive a free copy of the booklet, Statehouse Fossils: A Guide to Fossils of the Ohio Capitol.

Please RSVP for the Statehouse Fossil Tour by October 9th via this form: https://docs.google.com/forms/d/e/1FAIpQLSc3OsgTrYpqVBnxirpL67IyBHjF9y182Nj9oDAPNh8SxPLmoA/viewform?pli=1

Hey, Ohio educators, do you want to celebrate Earth Science Week with your students? We can help!

We have official Earth Science Week teacher toolkits available. The toolkits include experiment instructions, a calendar, posters, activity sheets, and more materials for teachers to use in the classroom. Toolkits are free and available for pickup at our Geologic Records Center in Columbus for any Ohio teacher (including home-school educators) while supplies last. Shipping is available for $5.

Teacher toolkits, maps, and other publications can be ordered by contacting the Geologic Records Center at (614) 265-6576 or geo.survey@dnr.

Join geologists Brittany Parrick and Douglas Aden to explore Ohio’s karst geology. Karst is a lesser-known but unique and important landform that can be found throughout the state of Ohio. Sinkholes are the main hazard associated with karst landforms in Ohio, with thousands of them across the state, including right here in central Ohio.

Participants will be guided through Wellington Park while learning about these geologic features, as well as the extensive karst mapping program the ODNR Division of Geological Survey has been conducting since 2011.

Hikers are encouraged to wear sturdy hiking boots and/or waterproof shoes, bring hiking/walking sticks, and have plenty of water, snacks, sunscreen, and bug spray.

Participants should meet at the playground by the tennis courts.

The event is free and recommended for ages 5 and up. For complete information, visit Ohiodnr.gov/events

The Ohio Geological Survey is now accepting applications for the Ohio Geology Student Research Grant program. For over a decade, this program has supported graduate and undergraduate students who conduct geologic research in the state.

We will award grants of $2,500 each to one earth science students at Ohio colleges and universities. Each grantee will be selected based on the quality of their application, the strength of their professor’s letter of recommendation, and how relevant their proposed research is to the Division’s mission and to furthering understanding of Ohio geology.

The deadline for application submission is Friday, December 4. To learn more and apply visit: https://ohiodnr.gov/buy-and-apply/apply-for-grants/grants/ohio-geology-student-research.

To round out our week by sharing our recent work in western Licking County, we asked our two lead authors for these maps, Tyler Norris and Andy Nash, to share their project highlights.

Click on each image to see these behind-the-scenes features of the mapping process.

We hope you have enjoyed learning about our new trio of geologic maps from western Licking County this week! We are continuing the fun with a behind-the-scenes look at data collection for Quaternary Geology of western Licking County, Ohio.

Our geologists collected a new, rotary-sonic drilled core reaching 435 feet that preserves a continuous record of glacial deposits down to their contact with bedrock. This video shows the whole process, from the field to the lab!

The third and final map produced during this STATEMAP-funded project is 𝘜𝘯𝘤𝘰𝘯𝘴𝘰𝘭𝘪𝘥𝘢𝘵𝘦𝘥 𝘚𝘦𝘥𝘪𝘮𝘦𝘯𝘵 𝘛𝘩𝘪𝘤𝘬𝘯𝘦𝘴𝘴 𝘰𝘧 𝘞𝘦𝘴𝘵𝘦𝘳𝘯 𝘓𝘪𝘤...

The third and final map produced during this STATEMAP-funded project is 𝘜𝘯𝘤𝘰𝘯𝘴𝘰𝘭𝘪𝘥𝘢𝘵𝘦𝘥 𝘚𝘦𝘥𝘪𝘮𝘦𝘯𝘵 𝘛𝘩𝘪𝘤𝘬𝘯𝘦𝘴𝘴 𝘰𝘧 𝘞𝘦𝘴𝘵𝘦𝘳𝘯 𝘓𝘪𝘤𝘬𝘪𝘯𝘨 𝘊𝘰𝘶𝘯𝘵𝘺, 𝘖𝘩𝘪𝘰. This map enhances the resolution of sediment thickness estimates across western Licking County by integrating multiple data sources to generate a raster derived from the bedrock topography and ground-surface digital elevation model. Sediment thickness ranges from 0 to ~512 ft (~156 m).

Congratulations to our fantastic staff, including Tyler Norris, Brittany Parrick, Molly E. Hunt, Andy Nash, and former Paul E. Potter Intern, Zach McClimon, on this publication!

Today’s map is 𝘉𝘦𝘥𝘳𝘰𝘤𝘬 𝘛𝘰𝘱𝘰𝘨𝘳𝘢𝘱𝘩𝘺 𝘰𝘧 𝘞𝘦𝘴𝘵𝘦𝘳𝘯 𝘓𝘪𝘤𝘬𝘪𝘯𝘨 𝘊𝘰𝘶𝘯𝘵𝘺, 𝘖𝘩𝘪𝘰, which details the subsurface contact between the bedrock surface and overlying Quaternary sediments (~2.58 million years ago–present). The result is a bedrock elevation model that depicts what the land would look like if soil and sediment layers were removed.

Bedrock elevation control points and locations were compiled from verified sources including water well logs, oil-and-gas drilling logs, test boreholes, boring geotechnical logs, ODNR field observations, ODNR karst features, and Horizontal-to-Vertical Spectral Ratio (HVSR) passive-seismic measurements.

Congratulations to our fantastic staff, including Tyler Norris, Brittany Parrick, Molly E. Hunt, Andy Nash, and former Paul E. Potter Intern, Zach McClimon, on this publication!
