Narrative:

Doing touch and go's practicing landing in tailwheel aircraft. The last half of the gravel runway has many whoopdeedoo's on it which is not stated in the notams for the airport. I lost control when the aircraft hit a dip in the runway and attempted to go around but did not have enough airspeed. I zinged off the runway resulting in left hand gear and prop being damaged.
