Mix your own drywall, in the comfort of your own home.

It turns out that gypsum is quite good when you want to make drywall. It's not so good when you want to make highways.

There are 2 large deposits of gypsum on the new section of the 101 between exit 4 and one the many exit 5s (5a, 5b, 5...well, you get the idea). In order to complete the lane addition project it is necessary to remove the gypsum and cart it off somewhere. ??? Not sure where, but somewhere (with the reduction of gypsum processing at the local gypsum factory it may not be there).

In the meantime, there is this drilling machine taking to the task of breaking up the deposits so that it can be carted away. A dustier job would be hard to imagine.
