Solution 2: Only let certain people climb the rock.
If only certain people that were trained and experienced got to climb the rock each year that would limit the amount of people climbing the rock and limit the amount casualties. The qualified climbers would most likely respect the rock better than others and keep it cleaner for the community. If a general member of the public wanted to climb the rock they could get a climb qualification so they would be able to climb the rock.
