This took longer than I thought, but that was because I didn't realize how little quality content some of the pages had, nor did I realize that none of the individual waterfall pages in Iceland had maps!
Well after this round of auditing and making drastic improvements to each page, I'm proud to say that the Iceland pages are now in a shape that I'm pretty happy with (consistent with overhauled regions done already). That is, all pages now have maps, more up-to-date content (with better directions and more information), more photos, new videos, and dedicated commenting for each waterfall.
Next up in the overhaul will probably be either Africa, South Pacific, and/or the Caribbean.
After that, there will only be Latin America and Asia to do.
