Hawaii
Kaluanni Gulch and Maakua Gulch are two beautiful, narrow canyons on the island of Oahu in Hawaii. In May of 1999, a large rock fall in Kaluanni Gulch killed eight hikers and injured many more. In an ensuing lawsuit, the state of Hawaii was found liable for their deaths since the canyon is in Sacred Falls State Park and people were allowed to hike in the canyon despite the known danger of rock fall. To avoid future legal liability, the state of Hawaii has permanently closed public access to these outstanding canyons. We will never be permitted to enjoy them in person, but perhaps we can gain some appreciation of their beauty from the following web-sites
