Stability of a circular cylindrical hole in a Glacier

Abstract If a bore hole of circular cross-section is made in an ice sheet or glacier, will it remain circular, or will it perhaps by some process of instability tend to depart from the circular shape? An argument is given to show that the circular shape is stable.
