Example (from the movie Willow Creek):
— Tell me a little bit about, um, the Patterson-Gimlin site and just how to get there, man.
— Oh, well, um, you can take this road, I can show on the map, and you go down that road. It's probably easier that way.
— That would be great.
— You come down to the bottom and there's an old camp site there, you know, and, uh, when you're at that camp site, you basically just take a right. You have to bushwhack and go through the forest.
— My girlfriend is OK with that.
— But it's not... you won't get lost. Just follow the sound of the creek on your left and look at the hill on your right. You just keep going straight between those until you come to a big gulch and you'll see it all blasted out with rocks and log debris and, uh, that's the bottom of the film site area.
I know it probably means covered with a lot of rocks in an unorganized way but what does it mean exactly to be blasted out with something?
