Chill the pie shell in the freezer while you prepare the filling. Place the softened ice cream, cranberry sauce, and orange juice in a large bowl and stir with a wooden spoon until the ingredients are well blended. Spoon the filling into the chilled shell and freeze the pie until firm (4 hours or more). Next, spread the whipped topping over the ice cream layer and sprinkle on the almonds. Cover the pie and return it to the freezer. Allow the pie to stand at room temperature for 20 minutes before slicing it.
