     We...saw "pahoihoi" or solid lava forming, and also "aa" or clinkers.

   • 1883 - Clarence E. Dutton in the fourth Annual report of the United States Geological Survey

     The second form of the lavas is called by the natives a-a, and its contrast with pahoehoe is about the greatest imaginable. It consists mainly of clinkers sometimes detached, sometimes partially agglutinated together with a bristling array of sharp, jagged, angular fragments.

   • 1944 - Charles A. Cotton: Volcanoes as landscape forms

     Cooling and solidification frequently takes a different course...in lava flows, producing the clinker-like "aa" lava.
