The Band in the Southern Sky

This is a request from a scholar who's doing research on constellations in the north. Apparently, a constellation that represents a river can be seen in the south. The client would like someone to do research on it since it can't be observed where he is.
A river constellation... I think you might be able to gather some information at the rest area.
