A yardang is a streamlined ridge of bedrock or other consolidated material carved by the combined action of wind driven sand and dust abrasion and deflation. A yardang typically grows to three or more times longer than it is wide, and viewed from above resembles the hull of a boat, presenting a steep, blunt face into the prevailing wind that gradually lowers and narrows toward its lee end. The shape reflects both the original distribution of harder and softer rock and the pattern of airflow that erodes the softer material away while leaving the harder material standing.
