For example, check out the rush Valley south of Tooele and west of Utah Lake. Overnight, temperatures bottomed out as low as 48ºF at the Faust MesoWest site along the valley floor compared to 60s in the Salt Lake Valley.

In addition, while it is cold at night, it is very hot during the day along the valley floor. Faust dropped to 48ºF, but it had a high of 95ºF yesterday.
So, if you want to cool off in the Rush Valley, you need to be a nocturnal animal.
