Recent investigations at Camp Fauld in Buchan, Scotland have yielded two peat deposits of pre-Late Devensian age. Percentage pollen diagrams are presented. One peat is radiocarbon-dated to 34-39 ka DP, which prompts correlation with the Hengelo-Denekamp sequence of NW continental Europe, but the pollen evidence, revealing the presence of a birch-pine woodland, suggests an earlier stage. The second peat deposit records an open shrub-tundra in which Bruckenthalia spiculifolia is present. The peat yielded a radiocarbon date of 40-51 ka BP, but is suspected of having been contaminated by younger carbon. That suspicion and the presence of Bruckenthalia suggest that a correlation, based on the radiocarbon date, with the Glinde interstadial, identified in NW Germany, would be incorrect. Correlation with other Scottish pre-Late Devensian sites has proved to be difficult.
最近在苏格兰巴肯的福尔兹营地进行的调查发现了两个晚德文期之前的泥炭矿床。文中给出了花粉百分比图。其中一个泥炭层经放射性碳测定年代为距今34 - 39千年距今年代（ka DP），这促使人们将其与欧洲西北部大陆的亨厄洛 - 德内坎普层序进行对比，但花粉证据显示存在桦树 - 松树林地，表明处于更早阶段。第二个泥炭矿床记录了一个开阔的灌木冻原，其中有尖叶布鲁克藓。该泥炭层的放射性碳年代测定为距今40 - 51千年距今年代（ka BP），但怀疑受到了较年轻碳的污染。这种怀疑以及尖叶布鲁克藓的存在表明，基于放射性碳年代与在德国西北部确定的格林德间冰期进行对比是不正确的。事实证明，将其与苏格兰其他晚德文期之前的地点进行对比很困难。
