We next traveled south into the Republic of Ireland to County Cavan. The area was dominated by limestone hills full of peat bogs and primeval forest. We were greeted by local expert Seamus who guided us throughout this dramatic landscape. The predominant substrate is limestone with giant boulders of sandstone dotted about. Remnants of human carving in the stone was evident. There were a number of very large stones that had been cut and then placed together to form niches. According to Seamus the excavations conducted at these sites showed collections of artifacts related to habitation over an extended period of time. The forest canopy was so dense in places that the under story was predominantly bryophytes, non-vascular plants. It was mind-boggling to think that much of this landscape was a shallow equatorial sea at one point in the distant past. We met a relative of one of Hawaii's native forest plants a Vaccinium sp. that was growing as ground cover.
