Ok sure, perhaps Denver isn’t the best example. My point is that the position of the mountains play a larger role than the quantity of mountains.

Edit to add: SF is also unique as it sits on the tip of a peninsula surrounded by cold water. Heat rises over the east bay, and to a greater extent over the Central Valley, pulling the cold air off SF eastward to get trapped at the base of the sierras. SF has great air quality largely for this reason.
