KÄINA, ESTONIA–Today we moved our geological investigations from Saaremaa to the island to the north: Hiiumaa. Our friend Olev Vinn of Tartu University then led us to an abandoned quarry in the Hilliste Formation (Lower Silurian). This made Rachel Matt very happy as it is the place she has been studying as the potential site for her Senior Independent Study project. First, it is not filled with water; second, it is easy to get to; third and most important, it has a diverse mix of fossils and rocks crying out for her attention. She is shown above in front of what looks like an ancient mud mound.
The rocks and fossils are so good that the students quickly accumulated a pile of cool specimens. I had to stop them from picking up fossils because we’ve not even started to sort out the stratigraphy. A good sign!
Our friend Bill Ausich at Ohio State University will be pleased to hear that there is much crinoid debris, as shown here in this image. It is a calyx plate in the center, with stem fragments around it. Hiiumaa is the island on the Euro to the right of the top star.
The only thing that I don’t like is that we’re on yet another island, and this one smaller than the last. So much water around so little land, and no way off except by these little ferries. Our car is the brown one in the front on the right. I’ll endure for science!
