According to the National Weather Service in Boulder this part of Park County gets so cold at night because it has clear skies, light winds and extensive snow cover. The combination of these three things leads to strong radiational cooling, especially during the winter, when days are short and the sun angle is low.
Temperature records for Antero Reservoir date back to the 1960s and history shows that -40 degree readings are quite common. There have even been a handful of days colder than -50 degrees. The all-time record low at Antero is -54 degrees.
