About RESC

Established in 1966, we are gathered from a variety of technical disciplines in the Greater Cincinnati area. If you are an engineer or scientist, either working or retired, join us for dining and scientific discussion/education with other members. We meet October through May to share knowledge and experiences while pursuing interests in technology and industry developments. All of our activities are nonsectarian, nonpolitical and nonfinancial.

Our activities include:
Lunch followed by
Technical Programs, often with PE CE/CPD credit
Tours of local centers of innovation.
Involvement and support in local S.T.E.M. competitions
and
a Summer GOLF league

Brief Summary of the Geologic History of the Tri-State Region; Implications for Current and Future Land Uses

by Dr. Dale C. Elifrits, Visiting Professor of Geology at Northern Kentucky University

photo of Dr. ElifritsThe terra firma beneath our feet in the Tri-State Region has been formed by many geologic events during the past 450 million years. Local surface bed rock formations composed mostly of shale with lesser proportions of limestone were deposited in shallow seas. Seas that covered this area at times received sediments from the rapid erosion of an ancestral Appalachian Mountain range alternating with times of quiet clear shallow sea carbonate (limestone) deposition for the period of some 450 to 400 million years ago, during the Ordovician Period. Deposition of sediments, thence rocks, continued for tens of millions of years from approximately 400 million years ago. But, subsequently, these younger rocks were eroded and removed leaving little of their record in the Tri-State. Uplift of the Cincinnati Arch some 400 million years ago created a gently uplifted “bow” in these sedimentary rocks. As the central portion of the continent was subsequently uplifted, this arch has facilitated deep erosion into the Ordovician age shale and limestone units in the Tri-State area.

More recently (nominally 2.0 to 2.5 million years to 20,000 years ago), continental glaciers moved generally north to south covering much of the Tri-State as far south as Walton, Kentucky, and then retreating at least five times. These glaciers modified the deeply eroded bedrock landscape including such actions such as blocking and re-directing surface drainage features and depositing sand, gravel, clay, and soil. The combination of steep slopes in the bedrock terrain, in-place weathering of the "soft" Ordovician age shale units on these slopes to produce weak clay-rich residual soils, and the glacial deposition of clay-rich soils have left less than stable slopes in the Tri-State area. Actions of society to modify landscapes for urban development have exacerbated problems presented by these less than stable slopes.

During this presentation the formation of the various geologic materials, the development of the current Tri-State landforms, and the interaction of these conditions with the actions of development will be addressed. Landslide process and landslide mechanics will be discussed. The connections between the natural resources provided by the Tri-State geologic conditions and the area's development and economy will be explored.

There will be a short Q & A time at the end of the presentation.





PE/CE Certificates

RESC offers PE/CE* Credit:

$5.00 for Non-members - Free to Members.

You are invited to join us for lunch at 11:30 am and attend the technical program for PE CE credit at 1:00 pm.

If you are unable to attend the luncheon you may attend the 1:00 pm program to obtain the CE Certificate but you must register with: Howard Heineke, (513) 733-4282, by 10:00 a.m. one day prior to the presentation or email CE Credit

To receive the PE CE Certificate, we will request your PE registration number and your PE name since certificates are prepared in advance.

According to our information OH, KY and IN have reciprocal agreements for PE credits.

There is no charge for attending just the program.

The Upcoming Tour


Make a tour Reservation:


Meet at 12:00 noon for lunch at the Four Seasons Restaurant at the marina (4609 Kellogg Ave, Cincinnati, OH 45226. Phone 513-871-1820)

We will then carpool to Verdin due to limited parking.

Verdin Bell Foundry (3900 Kellogg Ave. Cincinnati 45226) at 2:00pm on November 12, 2014
2.5 hrs duration

Since 1842, the Verdin family have created fine cast bronze bells, carillons, electronic digital bells, and tower/street clocks - with over 50,000 installations worldwide. Clients have included some 20,000 churches and the Smithsonian, Walt Disney World, and the World Peace Bell. Recently, on February 19, 2014, they cast a half scale Liberty Bell.

During the ~2.5 hr tour, we will witness the casting of a bronze bell at their foundry while the process is being explained.
