OTTUMWA ? Ottumwa-native Sarah Horgen, education and outreach coordinator for the University of Iowa Museum of Natural History, will be the speaker at the annual Borlaug Fall Seminar Oct. 15 at Indian Hills Community College.

Horgen will speak at 7 p.m. in room 5 of the Rural Health Education Center on the college?s Ottumwa campus. The presentation is free and open to the public.

Since 2012, Horgen has been assisting with coordination of an excavation for mammoth bones in Mahaska County where, so far, evidence of at least three separate wooly mammoths has been unearthed. The Mahaska County dig will be the topic of her talk.
