Red Rock Coulee Natural Area, AB.
Red Rock Coulee Natural Area is a small badlands reserve in the southern prairies, Alberta. It has a diversity of features from bare arid slopes to native grasslands and plateau. The main feature is a large area of exposed bearpaw shale containing more than a thousand rounded to ellipsoidal, red-orange concretions. These spheroids range in size from 1.5m to 2.5m in diameter and are exposed to varying degrees from the soft bedrock.
On the concretion section below, you can appreciate growth rings / concentric growth formed by calcite precipitation.
