A coffin is a combination jump seen on the cross-country phase of eventing. The obstacle involves jumping a set of rails, with one to several strides downhill to a ditch, and then one two several strides uphill to another set of rails ^* (and so the combination is also called "rails-ditch-rails"). Coffins used to be more pronounced in their change of terrain, with a drop down, to a ditch, to a bank up. However, the former type of coffin is the only type seen today.
