Catoosa, Oklahoma is a port town! It is known as the furthest inland, ice-free year-round seaport in the United States. Catoosa is linked to the Gulf of Mexico via the Arkansas and Mississippi River. During the days of the great cattle drives, Catoosa was the place to blow off steam and spend some money by the cowboys who had just been paid. It was named for nearby Catoosa Hill and was derived from a Cherokee word meaning "on the hill." If you drive down the old alignment of Route 66 in Catoosa you can still find relics from the golden years of Route 66 remaining.
