No way for a sunrise shot, because east is behind the waterfall, and because of the location of the waterfall, a sunset photo is also not possible, I think.
But thank you very much for your kind comment, @tomsmaid, and yes, Iceland would be a great place to stay for a while and take photos, thousands of photos ;)
A !BEER has to be cold and a !COFFEEA has to be hot to taste good and not !DERANGED 😉
