Well fire season has certainly picked up around these parts. The whole valley is filled with smoke from local fires as well as fires from northern California. It makes for some interesting field work for sure. Extraordinarily dry fuels, drought, and lots of lightning don’t help either.

What it looks like outside right now

But other than the fire chaos happening, I’ve been picking up new GIS projects for the minerals department. Mineral deposits are kind of a big deal down here as southern Oregon has plenty of mining history and even some of the towns are basically old gold rush towns. I’ve been digitizing maps of known deposits that correlate to the geology maps we have. We’re doing this to see what valuable areas may be within areas of critical environmental concern. In addition to that, I’ve been writing a lot of reports of the geology of the mining districts down here to help the archaeologists in our Abandoned Mine Lands program. The geology down here is quite interesting and can vary greatly between districts even though the spatial distance between them is small. For instance, one area may be a granite intrusion type area known as a porphyry style deposit, and another may be a volcanic massive sulfide type deposit which is basically a black smoker vent from an ancient sea floor that are now on land.

Studying and learning about the mining history and all the different types of geology around here is becoming quite the interesting project. Hopefully the smoke-filled valleys will die down soon and field work will be a little easier, but that may not happen anytime soon. Anyway, I’m off to Portland to the state office to help out with some GIS projects in minerals this week.

Until next time,
