Red Rock Coulee II

Red Rock Coulee

The most striking feature of Red Rock Coulee is the large, rounded sandstone concretions that can
measure up to 2.5 meters across. It is believed that the boulders were formed as calcite and iron
oxide collected around a "nucelus" such as a shell or bone. Layer upon layer of mineral was deposited
over a long time to produce the boulders.
