Our trip out west to Yellowstone and Grand Tetons was super. I experienced "dry lightning" and saw an actual wall cloud on the way out there. The wall cloud held together only about 10-15 minutes, but had a decent thunderstorm with it. You know that smell you have when rain is darn near your doorstep or during the first few minutes of a shower, usually most noticeable during sprinkles?
Well, when we actually did encounter rain out west, there wasn't an odor with the rain.The one band of T-storms we saw on the way out had what I call a rain-cooled fresh smell. Was in the low 90s with a breeze from the south but the storm we had saw winds change from the north, and when the rain came though, temperatures fell 25 degrees. The rain events that didn't smell were east of Rapid City, and once in Jackson Hole, Wyoming.
Any reason why the rain out there didn't smell?

Why didn't you smell this in South Dakota or Wyoming? It may be a function of topsoil. Here in the Midwest we have rich, deep loamy topsoil, the envy of the world in many respects. But the farther west you go the thinner the topsoil becomes (and the fewer spores available to mix with rain). That's the only thing I can think of offhand. Thanks for a great question!
