Frankly, this is just a bunch of fireworks from behind the branches of old cottonwood trees as seen from Watchman Campground in Zion National Park. BUT, why I shot this was to capture the sound of the fireworks echoing off the ancient sandstone walls of Zion Canyon. The echo seems to last forever. It's a great sound. If I had no vision I'd still be able to imagine the walls of stone because the sound and echoes create a sonic vision. I imagine the wildlife wasn't too happy about it though. Fortunately, many studies show wild animals and birds who share the same environment as humans become immune to the noise humans make. I've personally been involved in Fish and Wildlife studies proving this along the Oregon Coast where nesting pelagic and shorebirds barely react to the sound of 4th of July fireworks in the cities of Bandon and Depoe Bay.
