Rocks cracking apart due to global warming remains an unpredictable geologic event, but one of the rare places where it can happen is at the heart of a 150-acre preserve in Lincoln County, North Carolina.<\/p>\n

Known locally as the Beth Haven Flatrock, the granite outcrop represents what was once the volatile underside of the Charlotte region.<\/p>\n

The rock is between 250 million to 350 million years old, and formed when a magma intrusion got trapped under a large mountain range that rivaled the Himalayas, geologists say.<\/p>\n

Those \u201cgigantic\u201d peaks have long since crumbled, resulting in the emergence of a sprawling scab of granite that covers one-third of an acre.<\/p>\n

Such granitic flatrocks and domes are famous for hosting rare plant life, but scientists have become equally intrigued by the fact extreme heat can cause them to expand, crack and peel apart.<\/p>\n

These \u201cexfoliation events\u201d have actually been caught on video in other parts of the country, and they are every bit as strange as they sound. This includes the sound of cracking, rising dust and popping rocks.<\/p>\n

The Beth Haven Flatrock and surrounding 150-acres were acquired March 31 in a deal brokered by the Foothills Conservancy of North Carolina, Catawba Lands Conservancy, and The Conservation Fund, according to a news release.<\/p>\n

The site is about a 45-minute drive north from Charlotte and will never serve as a traditional park, due to concerns for rare plants growing on the rock.<\/p>\n

\u201cRock domes, with their onion-skin layers of exfoliation sheets, are among the most captivating landforms on earth,\u201d noted the 2018 study \u201cThermal influences on spontaneous rock dome exfoliation.<\/a>\u201d<\/p>\n

\u201cLong recognized as integral in shaping domes, the exact mechanism(s) by which exfoliation occurs remains enigmatic, mainly due to the lack of direct observations of natural events. In August 2014, during the hottest days of summer, a granitic dome in California, USA, spontaneously exfoliated; witnesses observed extensive cracking, including a … 17,636-pound … sheet popping into the air.\u201d<\/p>\n

Among the scientists who participated in the 2018 study is Martha Cary (Missy) Eppes of UNC Charlotte\u2019s Department of Earth, Environmental and Geographical Sciences.<\/p>\n

She visited the Beth Haven Flatrock in April, and says she found detached sheets of rock that could be attributed to exfoliation cracking.<\/p>\n

\u201cThere have not been enough of these events to know how to precisely predict them, but it is our hypothesis that extreme temperatures will cause more such events,\u201d Eppes told The Charlotte Observer.<\/p>\n

\u201cThe reason is that once you expose a rock to a certain temperature, it will crack in response to that temperature, but the next time you heat it up, it will not crack again until you exceed the previous temperature. This is called stress memory. It is a commonly documented phenomenon in rock and in fracture mechanics generally.\u201d<\/p>\n

That means the rock must continue to experience increasingly higher temperatures to crack.<\/p>\n

Visitors to Beth Haven Flatrock are unlikely to witness such an event, but that\u2019s not to say something won\u2019t be going on below the surface on extremely hot days. Flatrocks tend to be hotter than the surrounding area, and can reach temperatures of nearly 160 degrees, Eppes says.<\/p>\n

\u201cIf we deployed instrumentation that could listen for very small cracking, there\u2019s a good chance that you could \u2018hear\u2019 those crack events with that special instrumentation,\u201d she said.<\/p>\n

It\u2019s estimated there are at least 30 granitic flatrocks in North Carolina, but they \u201clook incredibly different\u201d from the Beth Haven Flatrock due to heavy foot traffic, researchers say.<\/p>\n

\u201cThe pristine nature of the Lincoln County site really impressed me. It made me (realize) that the other sites I have been to have been completely scrubbed clean of vegetation in many ways,\u201d Eppes says.<\/p>\n

\u201cIt also impressed me because it was this small little ecological and geological island hidden away in a very typical southern Piedmont forest.\u201d<\/p>\n

The site had been missed by state flatrock surveys, making the Foothills Conservancy announcement a revelation to researchers.<\/p>\n

In many instances, such magma intrusions take the shape of prominent domes \u2013 like Stone Mountain in Georgia. But the Lincoln County site is \u201csitting almost level with the surrounding landscape,\u201d according to Land Conservancy Director Will Ruark of the Catawba Lands Conservancy.<\/p>\n

\u201cIt\u2019s not an overlook with long-distance views. You\u2019re surrounded by trees with some open sky, and what really stands out is the contrast between the bare rock and the forest around it,\u201d Ruark told The Charlotte Observer.<\/p>\n

\u201cYou don\u2019t typically come across something like this in Lincoln County, so it really does feel like a small, self-contained natural world within a larger landscape. … The flatrock is not something you can see from the public road. Once you\u2019re there, it feels pretty removed. When you step onto the rock, everything changes.\u201d<\/p>\n

Preservationists sought to protect the site because it sits in the path of fast spreading development around Lake Norman. The resulting deal means the 150 acres \u201cis protected in perpetuity by a conservation easement,\u201d officials said.<\/p>\n
