| This year's Shiraishi Lab field trip started at a hot spring in Shimane. New discoveries were made around the geyser at Kibedani Hot Spring. By the time we reached the Shioido, the rain had become heavier. | |
 |
 |
| By the time we were observing the columnar joints at Tatamigafuchi, the rain had turned to snow. In the lodge, we had BBQ by avoiding the strong winds. | |
 |
 |
| The weather was rough the next day as well. We were unable to get close to the outcrop of Susa Hornfels. Akiyoshidai was also lightly covered in snow. | |
 |
 |
| Observing fossils at the Mine City Fossil Collection Site. In the evening, we enjoy curry supervised by Panday-san. | |
 |
 |
| In the morning, we observed the sedimentary structure of the Yuyawan Group. Afterwards, we moved to Shimonoseki and observed the limestone of the Toyonishi Group. We found traces of sample collection I had made over 20 years ago, and felt nostalgic for a while. | |
 |
 |
| This year's excursion ended with the observation of shell fossils from the Toyonishi Group and paleosols from the Kanmon Group. | |
