When you're at a particular level, and the end of your potential plummet is a heart-stopping, bowels-emptying distance below you, yes it is still heights. Even if the start of your demise begins at -83 feet.
There are very few deaths though I think four or five died in Cheve and I think three died in the Great Lakes area due to what we call break down. There really are not that many deaths in the NSS, those going outside of the NSS are at greater risk.
