The Beaumaris River flowed south from the Great Glacier, turned east and cut Vaasa in half, flowed through the Galena Mountains at Bloodstone Pass, and headed to the south into Damara. It was a meltwater river and was completely frozen during the winter. At other times it flowed very slowly and was shallow to such an extent that even small boats could not navigate its fords without being carried. The river had clean, refreshing cold water. In Vaasa it was frequented by goblinoids and the local people considered it dangerous to use for passage through the land.
The river flowed south into Damara and continued along this course for many miles until it turned to the northeast, where it flowed to Goliad. At Goliad it merged with the Goliad River and continued south to Heliogabalus where it flowed into Lake Mogador.
