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.
The Global Volcanism Program is not aware of any Holocene eruptions from Tlevak Strait-Suemez Is.. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tlevak Strait-Suemez Is. page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

|Scattered flat-lying basaltic lava flows with fresh pahoehoe surfaces occur near Tlevak Strait (lower right) and on the SW end of Suemez Island. The largest area of Quaternary basaltic rocks is located north of Trocadero Bay, the large embayment on the southern side of Suemez Island. Outcrops are located on western Prince of Wales Island (on the roughly rectangular peninsula NE of the northernmost point on Dall Island) and on nearby islands in Tlevak Strait. Quaternary basaltic rocks also occur along Bobs Bay on the NW side of Dall Island.
