This could be confusing; it's evolved over the years. The galleries are cumulative; one has the best waterfall shots from (in 2018 as I write this) 45 years of waterfalling trips. The other has the best or most interesting of the other shots I took during those trips. I thought some people would be here for the waterfalls and not interested in the other things, some of which are interesting too.
The folders are the entire trips combined for the last few years.
