Oops
for the record, a falling tree does make a sound
Never a dull moment around here. Yesterday was nonstop hubbub with Cousin Titi's visit and her daddy's birthday. They left for home this morning, so perhaps to fill in the quiet, a 70' (21 meter) tree decided to fall for no apparent reason. It's a sumac, which Wikipedia says reaches a maximum height of less than half that, so perhaps that's why it fell.

Big Mess
It just seemed to have been the tree's time. There was no storm, no wind... nothing special. Just a loud crack and, well, the sound of a tree falling, taking out a couple of other smaller trees with it along the way.

Collateral Damage
limb from a too-near Oak that took a four-foot long strip of tree with it

Sandbox
is under there somewhere
It fell right over the sandbox (seen here), taking out the redbud that had been shading the sandbox. Luckily no one was playing at the time.
Another photo that appeared on a blog post last year...

Playing In Front Of The Tree Last Year
Living around here, my folks are well versed in cleaning up after these things. I blogged about clearing a fallen tree a few years ago, and I'm sure I will again later this week.
The remnants of the 25"-diameter trunk were quite dynamic, with thick layers of multicolored wood....

Multicolored
Some large areas in the trunk had a whitish fungus or something, so that's probably why it fell, but no idea why it chose a calm, sunny day to do it.
