A presentation about sinkholes will be hosted by the Ohio Geological Survey at the Hillsboro library next week.
The program is set for Tuesday, Oct. 10, from 6:30 to 7 p.m. Presenters Douglas Aden and Brittany Parrick will also answer questions. They have been mapping sinkholes and springs in the Hillsboro region for three years.
According to Aden, Tuesday’s presentation “will focus on Highland County (and especially Hillsboro, Belfast, Sinking Spring and Peebles).”
“We will cover the methods we use to locate sinkholes, why we look for sinkholes, and how this area compares to the rest of Ohio,” Aden said. Potential geohazards will also be discussed, he added.
Sinkholes, Aden said, “cause much erosion in some places, provide a potential route for groundwater pollution, and can be a problem for some structures, including roads.”
He also said that locally, sinkholes tend to be “very circular (and) much smaller in area, but much more numerous than other parts of the state.”
As an example, Aden said that in north central Ohio, such as in the Bellevue area, sinkholes “are much larger and more irregular.”
Those topics and more will be discussed during next week’s presentation. All are invited to attend.
