A new exact solution of Glacier dynamics is presented here in terms of viscous-plastic theory of movements for 2-dimensional profile (x, y), where x(t) = y(t). Such a 2-D solution of Glacier dynamics could be associated with Riccati’s type in general case. Due to a very special character of Riccati’s type ordinary differential equation, it’s general solution is proved to have a proper gap for the components of a solution. It means a possibility of sudden gradient catastrophe at definite meaning of time-parameter (for 2-D flat profile of Glacier, (x, y)-components of ice velocity moving). So, Glacier might be moving suddenly with acceleration periodically: (x, y)-components of ice velocity achieve hundred meters /per day from few meters (per day).
