looks like it took a good whomping from something ... lol

The angle and weight of the branches simply split the trunk. Second major split.

Lots of timbet and wood. Is the wood from this tree any good for burning in pizza oven?

A two second google says willow makes poor fuel. Do you own the land? If not you cannot take the wood without permission.

Growing up, weeping willows were sometimes planted in suburban yards, and after a summer TStorm or winter ice-storm, that was a common sight.

i was told to never use it indoors... as it burns too hot.. and too fast ... probably a chimney fire hazard ... besides the fact that wood that burns too fast... means you spend more time hauling wood in ...

i have no clue .... how that info translates to a pizza oven ...

From what I read, Ken, it burns slow and cold. https://www.thestoveyard.com/resource-centre-home/what-wood-to-burn
