I think you have a valid point, although
National Geographic's October 2011 article on canyoning in New Zealand would certainly have a greater impact on those issues than exposing canyon locations on The Map.
Here are the photos from those canyons:

Do you have any information on the issues with New Zealand that you could educate us with? Can people visit these canyons responsibly?
Do similar canyoneering issues exist in Hawaii since the climate is somewhat similar (compared to Utah)?
Thanks for your input.
