| Abstract: | A small Holocene fan is forming where Queen Inlet, a hanging valley, enters West Arm fjord, Glacier Bay, Alaska. Queen fan
formed in the last 80 years following retreat of the Little Ice Age glacier that filled Glacier Bay about 200 yr BP. It was
built mainly by a turbidite system originating from Carroll Glacier delta, as the delta formed in the early 1900s at the head
of Queen Inlet. The Late Holocene Queen fan is comparable to large Pleistocene fans that formed in the Gulf of Alaska and
differs from trough-mouth fans formed by cooler climate glacier systems.
