It’s not uncommon for crescent-shaped swaths of sand to dot the shorelines of meandering rivers. These swaths usually appear along the inner side of a river bend, where the bank wraps around the sandy patch, forming deposits known as a “point bars.”
When they appear along an outer bank, which curves the opposite way, they form “counter-point” bars, which are usually interpreted by geoscientists as an anomaly: a sign that somethingsuch as a patch of erosion-resistant rocksis interfering with the…
