The simple things

We’re prepping to leave for South Africa and Namibia. I’m pretty much in full panic mode trying to get everything ready for launch.

It’s good to stop and appreciate the simple things in life… such as successfully extracting data from your differential GPS system and viewing the test path on Google Earth.

Ever wonder what a dolomitization front looks like?

Since I haven’t posted anything in a while here’s a fun picture. This is a dolomitization front penetrating into interbedded limestone and shales. Click for a larger picture after reading the description below (it’s worth it, trust me!).

Dolomitization front, Naukluft National Park, Namibia
Where dolomite is absent shales are purple and limestone is generally creamy. Within the dolomite zone the limestones have been alterted to dolomite and the shales have been altered to a green color. Awesome chemical reactions!
