Salt Lake City area is not particularly cold. It definitely gets hot in the summer, and snow in the valley melts within a day or so.

Looks like the cedar rapids site is also closed loop, with the full buildout being a hair over 1 gigawatt. Compared to salt lake city, colder in the winter, and a bit cooler in the summer but with very high humidity comparatively.
