Dr. Joel Fleischman is still painted on the Northwestern Mining Co. front window in the first scene after the opening credits.
When Maggie & Chris approach the garage where Roslyn and Cicelys vehicle is stored Chris' jacket is dry. When they reach the door Maggie moves to the window to peer in, the camera briefly following her. But when it pans back to Chris the back of his jacket is wet. It's such a brief pan that even if snow had fallen on Chris that it would have still been there as it wouldn't have had time to melt.
Marilyn tells the story of the founding of the town, wherein one of the two founding women loses a sock and stops to buy a new pair because she doesn't like to wear mismatched socks. Rather than wear mismatching socks she could have thrown the odd sock away - she clearly had other socks otherwise the story would say she had one bare foot. Furthermore, if there was somewhere to buy socks, obviously the town had already been founded and was large enough to include a shop that sold socks.
