Fireworks in Westcliffe

Fireworks

Independence Day fireworks at Lake DeWeese near Westcliffe, CO. July 4, 2010. Bottom thumbnail: Nature's fireworks, a creative assembly of 2 pictures. At the same time there was a thunderstorm to the north of the valley (to the south were the 4th of July fireworks). The two photos were combined. The spectators at the site must have seen those two kinds of fireworks at the same time.
