Hazards of Geology Field Work

Thanks to Magma Cum Laude for the excellent post on what we learn from geotrips! In sort of the same vein I offer the comprehensive list of everything that can go wrong on a geo-outing. I stole the idea some time back from a magazine ad for a water purification system, but I have continued to add new hazards as they emerge. I would be glad to add some of yours! If Murphy's Law applies, maybe by knowing every possible thing that could happen, maybe we can avoid them (fat chance...).
