Newly discovered Holocene volcanic vents, Port Moller and Stepovak Bay quadrangles, Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1983

Reconnaissance mapping in 1982-83 suggests previously unreported Holocene volcanic activity in the area 14-24 km southwest of Kupreanof Volcano (fig. 45). One young volcanic vent has been observed along the divide between Stepovak Bay and Bear Lake, and the locations of two others are inferred from the position of morphologically young lava flows mapped in valleys draining into Clark Bay, Grub Gulch, and Ramsey Bay. Other morphologically young flows extending northwest from the divide are evident on aerial photographs.
