Narrative:

When taxiing out for a VFR departure; the left main wheel of the C180 hit a block of frozen snow that was on the taxiway. The frozen snow was left over from a snowstorm that occurred five days earlier. When the left wheel hit the block of frozen snow left in the taxiway; the tail came up and the plane pivoted around the left main wheel. The right main then came into contact with the plowed snow bank that was left on the taxiway. This resulted in the tail coming up and the propeller came into contact with the ground.
