Found this guy, only thing faster than an '87 TW200... Was going to race but he was pointing in the wrong direction..
One of the things that this area (Hillsborough) used to have a boom with was gypsum. It's a sort of limestone that's used to make gyprock aka drywall.
There are several gypsum pits, and all kinds of underground tunnels and caves in the area due to pockets of gypsum that just dissolved away leaving caves and sinkholes.
And this is a little lake that was on my list to see, and I finally got a chance to take a ride there. Stanyard lake. Middle of nowhere, when I took this picture the silence almost hurt my ears.
