Hi H,
The early bird routine paid dividends for what is a really nice shot and it looks
like a beautiful clear morning.
As you are well aware, once the sun comes up, it can commonly cloud up there
very quickly and that is the last you see of the peak for the rest of the day.
I can relate to how cold it can get in that park - as in early warning signs of
possible hypothermia - better do something quick to get warm type cold.
