Damaged crank section of frame

Went out for a ride today with my Rockhopper and approached this section of the walkway that I thought was a smooth downhill, but when I realized it was large steps I panicked and put on the front brakes. Did it too abruptly that the rear went up, but not enough to throw me over. Not sure if this was when my chain popped off the front gears, but I believe it was... noticed it was off the gears and sitting on the frame part when I got down to the bottom of the steps. Friend told me to hold the back up and move the pedals and that the chain would eventually catch, which it did. Unfortunately doing so put some gouges in the frame as seen in this picture.

Should I worry about these gouges and should I get it repaired if it's even possible?
