It has been known to happen, so I may be wrong....
But I thought there was discussion on the "shoulders" of some of the greenside bunkers at Riviera
that had grown into the green surfaces, significantly impacting some old hole locations?
May have been when Crenshaw was involved.
Operating off memory, maybe front right of #16?
FWIW, and with absolutely no evidence, I believe the splashing of sand really changes the contours of the bunkers, as well as the
edges of the greens where shots are directed.
Practice bunkers show it quickly, but obviously that is extreme
