THE Big Dipper’s angle can be used to tell time at northern latitudes. It stays in the sky all night. I was told by a Blackfoot elder that they used it as a clock on clear nights.
The position changes with both time of night and time of year. Regular observers can tell time by the angle the constellation sits at.
