Natural features of the land do not, in general, create liability. Besides which states can't be sued except where their own laws allow it. Lawsuits over riptides on beaches or falling off the edge of mountains are not successful. There has also been a crackdown by state legislatures over high-risk activity suits and injury during commission of a crime suits. In most states you can't sue the slopes/resort for breaking your leg while skiing, nor can a burglar sue a property owner for any reason whatsoever (because the injury occurred during the commission of a felony). AFAIK the federal government also doesn't permit lawsuits over injuries in national parks or other such wilderness areas - not that you're likely to succeed. You knew or should have known hiking on the edge of the Grand Canyon is a high risk activity.
