Scattered flat-lying basaltic lava flows with fresh pahoehoe surfaces occur near Tlevak Strait and on the SW end of Suemez Island near the southern end of the panhandle of SE Alaska. Outcrops are located on western Prince of Wales Island, along Bobs Bay on the NW side of Dall Island, and at Trocadero Bay on Suemez Island. The flows overlie Paleozoic sedimentary rocks and are associated with Tertiary rhyolitic and dacitic lava flows on Suemez Island. The younger alkaline olivine basaltic flows were considered by Brew (in Wood and Kienle 1990) to be of probable postglacial age.
