Pricker Bushes, South African Barbeque and New Friends
On Friday, we decided to revisit an area we had already been to. This section covers the contact between the Bushveld rocks (green, colors as seen on the map) and the leptite (purple), granophyre (yellow) and granite (pink) rocks that we are interested in. What the map doesn’t show is topography. Pink granite can be very resistant, meaning it…

Diamond Mine Field Trip on Despite Strike
We woke up Wednesday morning to find out that all unionized government workers, including public school teachers, were on strike. All schools were shuttered and we worried that no one would show up for our workshop. But we arrived at class to find all of our teachers present. They told us this was a once…
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana.
