Colorado gets much nicer clouds than California. These appeared on the Old Ute Trail.
More clouds, looking east from the Continental Divide.
And these inocuous clouds, surrounding the Bear Lake trailhead, turned into a thunderstorm about an hour later, sending my hiking party scurrying for cover.
(If there are any meteorologists in the audience, I’d be curious to know what kind of clouds these are. I found some classification guides here and here but those Latin terms are all Greek to me.)
