I've got a giant pothole in my crushed stone driveway. It's about 3 feet
wide by 10 feet long by about 8" deep. I've heard of stuff called "driveway
mix", but I haven't a clue what's in it.

So, do I just get a yard of crushed stone and dump it in there? Or do I
need to get some of this "driveway mix" and use that? Or do I need to
excavate and install perf pipe or what?
