21. Ireland's geographic history covers everything from volcanism and tropical seas to the last glacial period . 22. The impact of earlier karstification ( solutional erosion ) has been eliminated by the last glacial period . 23. This limited glacial erosion also means that V�g?had limited glacier erosion during the last glacial period . 24. The earliest known settlers followed herds of large game to the region during the last glacial period . 25. The impact of earlier Karstification ( solutional erosion ) has been eliminated by the last glacial period . 26. Some sky islands serve as refugia for boreal species stranded by warming climates since the last glacial period . 27. Thus, the end of the last glacial period is not the end of the last ice age. 28. The last glacial period is called Llanquihue glaciation in Chile after the terminal moraine systems around the lake. 29. In this theory, small forest populations were retained within the affected region of the last glacial period . 30. Melting ice since the last glacial period has resulted in the preservation of a superb raised beach sequence.
