Note 186 — LEGENDS. (continued 3)
Reading edition
Tseʻ-zĭn-di-aí signifies Black Rock Standing (like a wall). It might mean an artificial wall of black rock; but as the result of careful inquiry it has been learned that the name refers to a locality where exists the formation known to geologists as trap-dyke. It cannot be averred that it is applied to all trap-dyke.
