Description

From Wood and Kienle (1990) [1] : "Flat-lying sodic alkalic olivine basalt flows with fresh pahoehoe surfaces occur in the vicinity of Tlevak Strait west of Prince of Wales Island, at Trocadero Bay on Suemez Island, and in valleys on northern Dall Island. The outcrop areas are indicated by Qb on the map [2] ."

Name Origin

"Tlevak Strait", as applied to the group of volcanic vents near Tlevak Strait waterway, is an informal name.
