Arabia Mountain is one of the two famous granite peaks in the Arabia Mountain National Heritage Area (AMNHA), located just east of Atlanta, Georgia. It’s a type of mountain called a monadnock—which means it stands out because it’s made of hard granite that resists erosion, unlike the softer surrounding land that’s worn away over millions of years.
In the quarried areas of Arabia Mountain, there’s a phenomenon called “pop-ups.” These are sudden events when pieces of granite break off from the surface of the mountain. This happens because of a natural process called exfoliation, where the outer layers of granite expand and contract as the temperature changes. Over time, this causes the rock to peel away in sections.
These “pop-ups” are more likely to happen on hot summer days, and they can be dangerous. The rocks may shoot out unexpectedly, so it’s important to stay a safe distance from the granite outcrops, especially when the weather is warm, to avoid getting hit by falling rocks.
About the Arabia Mountain National Heritage Area (AMNHA)
The Arabia Mountain National Heritage Area is a unique landscape just east of Atlanta, known for its beautiful granite outcrops and rich history. Spanning over 40,000 acres, it includes not only the stunning Arabia and Panola Mountains but also former quarries, agricultural sites, historic communities, and spiritual centers.
The area has a deep history, from Native American settlements to European settlers and enslaved Africans. Arabia Mountain was once a major granite quarry that supplied stone for structures like the U.S. Naval Academy. Panola Mountain, however, was spared from quarrying and remains a pristine natural space with rare plants and wildlife.
Today, visitors can explore hiking, biking, and nature trails, and discover historic sites like Vaughters' Farm and the Flat Rock community, one of Georgia’s oldest African-American communities. The Monastery of the Holy Spirit, a peaceful retreat, is also located here.
