Source: https://youtu.be/afqU-kGekgM In a video on Facebook, some people who seem to suspect the wildfire in Paradise was made with lasers are stumped by a hole in the ground. They can't understand why some trees seem to have burnt all the way down to the roots, leaving just a hole. "What happened here" is not an unreasonable question, especially for city folk who might not be familiar with tree stumps, or burning wood. So I set out to investigate. Firstly I found the location of the house in the video (Hillpark Lane), and the obvious thing was that you can see (in 2012, when these street-view images were taken) tree stumps where there are now holes in the ground, and you can see a live tree where there is now a burnt stump. So, old rotten stump burnt completely, newer stump burnt partially. This makes perfect sense if you look at some tree stumps. After a few years, they get rotten, and you can just poke them to pieces. Once dry (like at the end of the summer), those pieces will burn very easily. Where's all the ash in the hole? This video was taken after several inches of rain fell on Paradise, washing it all away, and eroding the hole some more. So all we have here is some old rotten stumps burning away, leaving holes in the ground.
