The footage shows the Jeffrey pine, believed to be at least 200 years old, on fire after the lightning strike. After a few minutes, the trunk simply splits in two, with the flaming pieces falling to either side.

The footage of the tree, across the street from the Big Bear airport, was captured by Michael Bogan, who says he saw and heard the flash of lighting. He tweeted: "It was a gorgeous 200+ year old healthy tree that had an unlucky day."
After putting out the flames, firefighters later cut down what was left of the tree.
The San Bernardino National Forest fire agency said firefighters responded to five separate incidents of trees being set on fire by lightning strikes on Saturday.
