@EchoTangoSuitcase I'm not 100% sure, but I think our D1 is crushed granite. It's a non-frost-susceptible crushed aggregate, with less than 6% fines. It's a state specification, and used a lot here for driveway, road, and concrete slab bases.
@@alaskanhomesteading - I was curious, because in the video it looked like limestone, but then I remembered I couldn't find any when I looked a few years ago.
You're crushing it.
@@finnthehuman3940 I see what you did there
Is that limestone?
