In early November the latest sunrise of the year in Denver takes place. Sunrise was at 7:32 AM MDT, tomorrow sunrise is at 6:33 AM MST due to the end of Daylight Saving Time.
When I arrived at a popular location to photograph Denver I noticed there were clouds to the east of downtown Denver. The key with the clouds is if they are thick are thin clouds which will light up just prior to sunrise. I got lucky this morning with vibrant color for a couple of minutes providing this look of downtown Denver.
