Wow, thanks for that, Tibbs. And thanks for the vote of confidence, folks. I find it really hard to be objective with my shots. I would have voted for somebody else's (and what a choice there was!) if I'd voted.
It was very definitely right place at the right time - but I'm now planning on trying to replicate the conditions. I started back from Waterfall Valley Hut at nearly 5.30pm, having helped some friends doing the OLT. That was much later than I planned, for reasons I was quite grumpy about at the time. But as the sun was setting, and I had the plateau to myself, with magic light, no wind and oceans of cloud in the valleys, my cup was overflowing big time.
I nearly didn't submit the photo, because it's too soft - i can't get sharp shots on either of my cameras.

So thanks, naturelover, for saying you liked it a while ago, which made me cautiously enter it here. Not happy with the contrast & brightness - it doesn't capture the real glow, but there you go.
