Distributary of Ustay River, flows SE to the Alsek River 2 mi N of its mouth and 48 mi SE of Yakutat, Malaspina Coastal Plain.
HistoryLocal descriptive name reported in 1927 by U.S. Geological Survey (USGS). Captain Tebenkov (1852, map 7), Imperial Russian Navy (IRN), shows five outlets of the Alsek River and one he recorded as "Kakangina Kakanhini," meaning "stickleback river." Lieutenant Commander J. F. Moser, U.S. Navy (USN), found the Alsek to have only three main outlets. Just west of these is the "Ko=kon=hee=ni" an outlet of the Ustay River. It is this latter application that is now called "Muddy."
