Peter Sinks, Utah: One of the coldest places

The Peter Sinks in Northern Utah (near Bear Lake) is one of the coldest places in the lower 48 states.
Some info here: https://climate.usurf.usu.edu/PeterSinks/

From MesoWest: the PSINK and PSRIM sites at midnight on December 8, 2016

The temperature gradient between the rim and the valley, a 270 foot vertical difference, can be quite large. Over the last two days temperatures have plunged below -40 C.



Max, min, and mean temperatures for the two stations are shown below (need to apply some quality control on the data from the MesoWest API seeing that there is a max temperature in September of over a 105 F, which seems odd) Still, it is often quite cold in the Peter Sinks.
