The historic cold blast settling into Alaska at the end of the week sent temperatures plummeting far below zero, so cold, in fact, as to topple several long-standing records.
Fairbanks dropped to a staggering 27 degrees below zero on Friday, smashing the century-old record of 16 below zero from 1911.
Cities like McGrath and King Salmon also dropped below zero, and set new records.
Even in cities like Anchorage, where the temperature didn't drop below zero, the mercury in thermometers did fall just enough to still break the daily record from 1986.

The cold front moved in over Tasmania, Victoria and South Australia on Saturday, bringing freezing conditions, low-level snow, heavy swells and the first frost of the year.
Melbourne on Sunday woke to its coldest morning since October 20 last year according to the Bureau of Meteorology, with the mercury dipping to 8.3C.
Whale sharks are the largest fish species in the world and can grow to 10-15 metres, but Matt Azzopardi and his family who reported it to Fisheries and National Parks measured it to around four metres.
"It was an incredible experience - we thought it was still alive coz it was rolling in the surf," Matt said.
"It was quite surreal to see it, I paced it out myself to a conservative three and a half metres to over four metres."
Fisheries have since measured it to almost exactly five metres.
Matt made the find with his partner Allison Falzon and their two sons Mason and Jakim, sharing video to their Facebook page Shotgun Odyssey - Travel Oz.

Pieces of roof tiles and other debris litter the ground at a school following an earthquake in Malang, East Java, Indonesia, April 10, 2021.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Saturday 10 April 2021 at 2:00 pm local time at an intermediate depth of 87 km.
The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.9.
Images and videos from the region showed the hail as it pelted vehicles and left dents in their wake.
Police cars on the scene of an earlier mass shooting were among the damaged cars, according to KBTX-TV.
The flagship campus of Texas A&M University in College Station was covered in ping pong-size hail after the storms passed.
Severe thunderstorm and tornado warnings were issued for the region as the system moved eastward.
The epicenter, with a depth of 10.0 km, was initially determined to be at 3.4527 degrees south latitude and 145.7212 degrees east longitude.

The opening stage of the Tour of Turkey has been cancelled after heavy snow covered the elevated hills between Nevşehir and Ürgüp in central Turkey that were due to host Sunday's first stage.
Riders awoke to heavy snow falls on Saturday and with more wintery conditions expected, race organisers were forced to cancel the stage.
The 167.3km stage was due to climb up to 1400 metres five times from a start point of 1200m before finishing in Ürgüp but the weather conditions made racing impossible.
Officials said the second, much longer whale washed up on Himchhari Beach, outside the resort city of Cox's Bazar, at around 8:30 a.m. (2:30 a.m. GMT) Saturday, just a day after the carcass of another Bryde's whale was found 2 kilometers (1.25 miles) from the spot.
"The carcass of the whale found today is at least 50 feet (16 meters) long and 10 feet wide. It weighs 3 to 4 tonnes," Jahirul Islam, executive director of the Cox's Bazar-based Marine Life Alliance, told AFP.
Islam said the whales could have been killed in a collision with a ship plying the Bay of Bengal, or have died after eating plastics that litter the sea.
Principal Jennifer Johnson says it happened at about 8:25 a.m. while 9th and 10th grade students were preparing to take the ACT Aspire test.
No one was hurt and there was no damage to the school.
"Initially, the students and staff were startled by the event; however, after realizing what had just happened, they were fascinated by the rare incident that occurred just feet from them," said Johnson.
