help me identify these trees please.

Wondering if the wood will be good for hugelculture beds, but need to identify them first. Thought they were some sort of locust however they don't look like any photos of any locust I find on the web.

they get up to or around 70'+ tall, big taproot, when we cut them down the stumps branch out with some very thorny shoots, the main branches have alternating compound leaves with a bunch of leaf petals across from each other. leaves turn yellow in fall, they blossom white in spring. Not sure what the fruit looks like but it's not a big pod, if anything it's a helicopter style seed leaf.

Probably Black Locust.

photos were jumbled between honey locust and black locust. Looking specifically at black locust photos now and yep that's what they are. Thank you!

Black locust takes a long time to decompose and is made of a lot of heartwood, which can resistant to absorbing water.

Usually people make outdoor things with them because of their extreme strength and durability. 100+ outdoors and in soil.
