what is this woody, thorny bush in my back woods?

Asked April 20, 2020, 6:57 PM EDT

I live in minnetonka and have a small wooded area, while removing buck thorn I noticed a patch with a thin, woody, thorny bush/tree?. the bark is reddish with white spots and lots of thorns. I hope this picture attached will help some. thank you for your help!

Thanks, Evelyn! Assuming I should leave it growing (that it isn't invasive), I will keep an eye on it interestingly this summer.
