A close-up capture of a portion of the Finger Rock Fire, a lightning-caused fire burning in the foothills of the
Santa Catalina Mountains north of Tucson. The fire was burning well away from civilization in very rugged terrain;
the forest service let this burn because there was no real threat. As of the next day it had died down considerably
and I could only see a few small spots still burning the following night. Not as bad as previous wildfires in the Catalina Mountains.

This image reminds me of the views I've seen looking through a large telescope at some galactic nebulae.
For context, this is a close-up view of one of the steep mountain faces, with each speck of light representing
some burning material; I know it may appear as though those are sparks, but that is just an illusion with this image.

Now, the cool part of this is that I took an image of this when it started from a lightning strike eight days earlier.
I was setting up the camera when I saw the lightning strike and took the picture below about a minute later:



And some of the lightning activity in the area just prior to this strike:





And another view of an area of this fire that was burning much more vigorously:
