Llanddwyn field trip

This year I had two field trips in a row: on the Tuesday, hunting glacial striations, and on Wednesday, showing freshers Llanddwyn. We didn't have that many people on the module this year. That means: only one vehicle, and we decided to only go with two staff. Jaco stayed home. 

Dei and I had divided up the talking points. And I think it went well! I started on the pillow lavas, which he continued on the next outcrop, and then I talked about the much messier basaltic deposits a bit further on, and the mudstone with sand lenses. Dei then showed us some hydrothermally altered muds, and I talked about the limestone. And Dei finished off with the melange at the far end. By that time you could tell that the students had pretty much maxed out on information intake! And we were actually quite tired ourselves. It was time to get back. And not only because we needed to be mindful of the tide, which can cut off the way back to the beach.

I think it went fine! And next month, we probably do something not dissimilar, in the Cemaes area. If the weather is as good then, I expect the trip to be as good!
