HB: waterway=waterfall seems to have gone out in of favour of natural=waterfall. For point nodes natural= seems better to me, for ways waterway= seems better to me. For polygons and edges..??
Q: what does "edge" mean in this context?
A: it is the precipice perpendicular to the river, the line you really don't want to cross in your canoe. I'm not sure how to tag that...
Should we add tourism=attraction for named ones??
HB: added natural=cliff, changed to waterway=waterfall. after upload we need to edit line direction so that top of cliff (upstream) is on the left side of the way. (51 to check by hand)
