I’ve experienced -35C in Harbin during a winter (2005). My digital camera battery kept dying, it made taking pictures of ice sculptures (including a full ice bar) really hard. What is weird is that Harbin is super populated and not that far north (it’s a couple of degrees south of Seattle).

What was weird is that the bus I took from Changchun had a digital thermometer up front where you could see it fall from around -25 to -35 during the trip.

My mom was born and raised in Alaska, but Ketchikan is closer to Seattle in climate and distance than anchorage.
