That took me a while :-) It’s a lovely region to tour by map, but I started at
PABR when I eventually realised that you meant PAFR because Browerville is
nowhere near Anchorage. I saw all sorts of new, foreign, names in my travels.
And I like Skyvector, which I’ve never seen before. I might be able to use
that . . .
That valley does look tight, and I can imagine the rotor action caused by high
winds across the ridges; what a place!
I can see that a real 21mm would make that composition and I do like it.
I also recognise the wisdom in your use of HDR in this sort of situation, and
with such a place to photograph.
