Scheduling a Visit to
the H. R. Collins Laboratory
Guided tours of the H. R. Collins Laboratory (HRCL) and lectures about the geology and fossils of Ohio are available upon request. Tours for individuals and groups up to 40 are conducted during normal business hours (8 a.m. to 4:30 p.m., M–F) and generally last about an hour.
Each tour will provide visitors with information about one of Ohio’s most unique libraries—a library of miles and miles of rocks that tells the story of the geology buried deep beneath Ohio’s landscape. Division of Geological Survey geologists are available to lead each tour and answer questions concerning the HRCL and the geology and fossils of Ohio. Please contact Aaron Evelsizor (info below) to schedule a tour or lecture.
Each year the HRCL holds a limited number of geologic workshops for students, faculty, industry, and consultants. Workshop topics vary and will be advertised via the Division of Geological Survey website and other media outlets.
Walk-in visitors are always welcome. However, visitors planning to examine or sample the collections housed at the HRCL should schedule an appointment one to two weeks prior to their arrival. Access is given on a first-come, first-served basis unless special permission is given by the Division Chief. Please take a moment to review our core-use and cutting-use policies and the Compensation in Appreciation of Services schedule. To schedule a visit, please send a brief e-mail to Aaron Evelsizor describing the following:
- Cores, samples, and collections to be examined
- Duration of study
- Anticipated reports or publications
- Mailing and e-mailing addresses
- Telephone number for each investigator
