Help me understand this Jasper-like rock.

I find a lot of this type of stone that looks like it was used as road construction fill along the irrigation canals in Central Oregon. I am curious to understand what it might be and where they would’ve brought it in from.

Waxy like texture, steel does not scratch it. The fracturing does not look conchoidal to me as I would expect from Jasper.
