The book "Younger Dryas" by Betascript Publishing offers a comprehensive analysis of the Younger Dryas, a geological cold period that occurred approximately 12,800 to 11,500 years ago. This period, also known as the "Big Freeze," followed the Bølling/Allerød interstadial and was characterized by significant climatic changes. The title refers to the alpine wildflower Dryas octopetala, which was common during this time. The book highlights the impacts of this cold period on the environment and wildlife, as well as the various regional names associated with this period, such as the Nahanagan Stadial in Ireland and the Loch Lomond Stadial in the United Kingdom. It is a valuable resource for anyone interested in the climatic and geological developments of the late Pleistocene.
