In August, a chunk of plaster broke off the side of the man-made mountain forcing the closure of one of the tracks until repairs could be made.
Graveyard shift maintenance crews found the rockwork, which had fallen while the park was closed. No guests were ever at risk and the plaster did not make impact with the track.
Disneyland officials confirmed to the Orange County Register that the attraction should be back to normal beginning today.
