Do you associate volcanoes with North Carolina?

Now that I have your attention… today’s blog post is about ancient history. This is one of the topics I wrote about in Harrisburg, Did You Know? Cabarrus History, Book 2.

Harrisburg, North Carolina sits inside a 22-mile syenite or ring dike. One can get a feel for it from several high points in the area, such as when traveling south from Concord on US-29 near the intersection with Union Cemetery Road. It’s like looking across a gigantic bowl.

Another possible place from which to catch a glimpse of the “bowl” is on NC-49 southbound after you pass Old Charlotte Road. The Charlotte downtown skyline is visible briefly from that location as well as the one referenced above on US-29.

Harrisburg, Did You Know? Cabarrus History, Book 2, by Janet Morrison

What, you may ask, is a syenite or ring dike? I’m no expert on volcanology, but my understanding is that it is a circular dike around a volcano.

According to 2001 Encyclopedia of Earthquakes and Volcanoes, by David Ritchie and Alexander E. Gates, Ph.D.:

“If magma is removed from the magma chamber beneath a volcano, it can undergo caldera collapse. The volcano and the area around it collapse because they are no longer being held up by the liquid. A series of concentric faults and cracks develop around the collapsing volcano. As they do, magma will squeeze up around the cracks and faults forming ring dikes.”

I’ll take their word for it.

In 1966, U.S. Geological Survey geologist Harry E. LeGrand and Henry Bell III led a scientific excursion in Cabarrus County to study our ring dike and other interesting rock and mineral deposits in the county.

You might be able to access a pdf of “Guidebook of Excursion in Cabarrus County, North Carolina, October 22-23,1966” by going to https://www.carolinageologicalsociety.org. Search for “1960s Field Trip Guidebooks” and then scroll down to find that particular guidebook.

The Harrisburg area has experienced a population explosion since 1966. The landmarks noted in the 1966 guidebook are either gone or more difficult to locate today. The concentric rings that were reportedly visible from the air in 1960 by R.G. Ray might not still be intact.

Copies of Harrisburg, Did You Know? Cabarrus History, Book 1 and Book 2 have arrived and been autographed.

Photocopies of my 11×14-inch “Harrisburg in the 1900s” two-map sets have been made.

Business cards and bookmarks are printed.

Saturday, April 15 is the big day for my Meet & Greet at Second Look Books in Harrisburg, North Carolina! I’ll be there from 2:00 p.m. until 4:00 p.m.

Please drop by, even if you’ve already purchased both books.

The bookmarks and Harrisburg maps are free while supplies last.

What maps?

I drew the maps based on detailed memories that Mr. Ira Lee Taylor shared with me while I was writing the “Did You Know? local history column for Harrisburg Horizons newspaper (2006-2012.)

One map covers from along NC-49 to Back Creek. The other map covers from Back Creek to Reedy Creek and where McKee Creek flows into Reedy Creek.

Mr. Taylor told me where such things as the telephone switchboard, spoke factory, two cotton gins, railroad houses, corn fields, cotton fields, and livery stable were in the early 1900s.

He told me where the various stores and post offices were. Being the town’s only mail carrier for several decades, he knew where everybody lived, so I included much of that information The map show where the roads were (and were not) before the coming of the high-speed rail.

In case you arrived in Harrisburg after the two-story red brick old Harrisburg School was torn down, this set of maps will show you the layout of the school grounds. The school property is where School House Commons Shopping Center is now.

The maps also show the locations of the Oak Grove Rosenwald School and the Bellefonte Rosenwald School that you read about in Harrisburg, Did You Know? Cabarrus History, Book 1.

Some things you’ll learn about in my two books

There are stories of local heroism from 1771 and the detailed memories of a World War II US Army veteran who told me about his training for D-Day through to the end of the war.

There are stories about the original Hickory Ridge School, which was a one-room school on Hickory Ridge Road.

There are stories about the Rosenwald Schools that served the black students in the early 1900s.

There are stories about the man from Russia (actually, Ukraine) who settled in Harrisburg in the 1920s to practice medicine until his death in 1960. He was a country doctor who made house calls

There are stories about the construction of the Charlotte Motor Speedway and the first World 600 Race when the track was in such bad shape that chunks of asphalt broke the windshields out of some of the race cars.

There is information about the 22-mile syenite ring-dike that Harrisburg sits in. It’s what remains of an ancient volcano.

Until my next blog post

Remember the people of Ukraine – where Dr. Nicholas E. Lubchenko was born and lived until young adulthood.

I hope to see you on Saturday!

In case you don’t have a good book to read, please consider purchasing my local history books. They’re available in paperback at Second Look Books. They’re also available in paperback and for Kindle from Amazon.

Even if you don’t live or have never lived in Harrisburg, North Carolina, I think you’ll find some interesting stories that you can probably relate to if you are of a certain age. And if you a child, teen, or young adult I think you’ll find it interesting to read about how life used to be in our sleepy little farm village of a couple hundred people in the early 1900s that has grown to nearly 20,000 people in 2023.
