An Angel?

Up in northern California at the end of June 2009, we visited the Big Tree's State park.
Here's is what appears to be a Angel...
about 2 seconds later...nothing.
But then on the next frame, I get this...and it appears that Dyllan is watching it. (I was not aware of any of this till I saw the images on the computer later)
After taking a few shots of Dyllan, I snapped off a few more at the trees roots as I was "drawn" to their beauty...

It seems, whatever I captured started to dissipate upwards till it was gone.
What a visual treat!
