The reason for the timing and occasion of the Geological Society of America (GSA) Penrose Conference held in the medieval town of Apiro on 25–30 September 2017, in the foothills of the Marche Apennines of central Italy, was the celebration of the 25th anniversary of the Geological Observatory of Coldigioco (OGC), an independent research and educational center founded by Walter Alvarez, David Bice, and myself in 1992 in a semi-abandoned hamlet called Coldigioco. At this conference, some 60 attendees, mostly academicians and/or researchers, convened from 11 countries (Australia, Austria, Belgium, China, Croatia, Italy, Netherlands, Norway, Sweden, UK, and USA; Fig. 1), including a group of auditing students from the Associated Colleges of the Midwest (ACM), who were in Coldigioco at that time for a 12-week environmental sciences field course. The attendees presented some 70 original research works and reviews in the form of keynote, oral, and poster presentations, covering specific subjects related to topics in tectonics and structural geology, integrated stratigraphy and astronomical tuning, event stratigraphy of extraterrestrial impacts, and Quaternary geology and geobio-speleology, most of which were focused on the Umbria-Marche Apennines.

250 Million Years of Earth History in Central Italy: Celebrating 25 Years of the Geological Observatory of Coldigioco
Central Italy has been a cradle of geology for centuries. For more than 100 years, studies at the Umbria and Marche Apennines have led to new ideas and a better understanding of the past, such as the Cretaceous–Paleogene (K-Pg) boundary event, or the events across the Eocene–Oligocene transition from a greenhouse to an icehouse world. The Umbria-Marche Apennines are entirely made of marine sedimentary rocks, representing a continuous record of the geotectonic evolution of an epeiric sea from the Early Triassic to the Pleistocene. The book includes reviews and original research works accomplished with the support of the Geological Observatory of Coldigioco, an independent research and educational center, which was founded in an abandoned medieval hamlet near Apiro in 1992.
