The University of New Hampshire\’s Center for Coastal \& Ocean Mapping collected ~321,500 km2 of bathymetry and backscatter data of the U.S. Gulf of Alaska continental margin (Fig. 1a) using a 12-kHz multibeam echosounder in support of the U.S. Extended Continental Shelf (United Nations Law of the Sea Treaty) project (Gardner and Mayer, 2005). A previously unmapped small submarine fan, unofficially named Chatham fan (Figs. 1b and 1c), was identified that has buried a portion of the head of the much larger Baranof Fan (Stevenson and Embley, 1987; von Huene, 1989; LeVoir et al., 2011). Chatham fan either buried or diverted to the NW the upper reaches of Horizon Channel. The existing levee of upper Horizon Channel was subsequently incised by a remarkable meandering channel that trends along the strike of the levee, not down the steeper lee side of the levee slope. Although not directly related to Chatham fan, the meandering levee channel is related to processes that were contemporaneous with the deposition of Chatham fan. \
