Thank you everyone for your comments. Much appreciated!
These young women and the older ladies acting as their chaperones are from the Mennonite ethnic-religious group so they wear simple, longer dresses in pretty, soft colours and small white caps. This is referred to as dressing "plain". Mennonites are active in various peace and social issues. These women were very friendly & sweet, chatting & happy. They were taking a bus tour through Acadia National Park in Maine (USA). Almost everyone had a small point-and-shoot.
Yes that is for sure flare in the sky. In this case with the "full-spectrum" D600 and the red filter on the Fishie, I thought it added to the unreal, Martian look.
