At about 10:45 pm, 8 July 2018, we heard loud crackling sounds, followed by breaks, crackling and thuds. Heather and I went over, using spotlights, and found that a number of branches of large valley oaks had broken off. I took these photos the next morning. It appears that five large branches fell, from three different valley oaks. A dominoes effect must have occurred, with one very high branch taking down another, high branch on a different tree, and they took out everything beneath them.

This large valley oak lost a large branch at 10:45 pm, 25 June 2015, Gold Springs, Columbia Ca. We heard what sounded like gunshots, off and on for a couple of minutes, followed by what sounded like fireworks going off, before it became clear it was tree falling. There was no loud crash, however. Investigating the next morning, we found that a large branch of one of the giant valley oak trees had fallen, breaking a limb off an adjacent live oak, before ultimately landing in the crotch of the live oak, causing a big rift in its trunk.
