The Lune Gorge and the uplands of the southern Shap Fells represent a key area in developing an understanding of the dynamics of the Late Devensian glaciation (Dimlington Stadial) of northern England. Here ice masses emanating from southern Scotland, the Lake District and the Howgill Fells interacted in the area of the upper Lune valley. Glacial landforms are recorded and tills noted. The dispersal pattern of Shap granite (Sg) erratics is mapped as these clasts are an important tracer of regional ice movements and local ice dynamics. This new information is synthesised with existing literature to provide an understanding of ice dynamics in an area of complex ice flow history. In particular, the ice flow interactions over an area of the western Pennines and the southern Shap Fells have been defined.

Early Dimlington ice flow in the vicinity of the upper Lune valley was easterly. Later a northerly shift in the position of a regionally significant west–east aligned ice divide led to topographic steering of southerly basal ice flows, resulting in the development of a western ice stream (Mint Sg plume) and an eastern ice stream (Lune Sg plume); both flowing south around the massif of the southern Shap Fells. At that time, southerly flow of basal ice over the highest ridges of the Grayrigg massif in the southern Shap Fells was relatively weak. Whereas the western stream extended into the Lancashire lowlands, the eastern ice stream was impeded in the Lune Gorge by ice emanating from Borrowdale which forced northern ice to the eastern side of the Lune Gorge where it was blocked by western flowing Howgill ice; the latter extending as far as just east of Kendal.

During the late Dimlington, the ice masses over the Mint valley and the southern Shap Fells largely thinned and retreated to the north and west, with a surge in northerly ice movement within the upper Lune valley that did not override the western Pennines. Local ice dynamics are well-illustrated in the western margin of the Pennines (Crosby Ravensworth Fell Gaythorne Plain), where the disposition of erratics reflects local late west-to-east weak down-wasting ice flow and the presence of subglacial meltwater drainage channels. However, ice ultimately decayed in situ on Crosby Ravensworth Fell Gaythorne Plain. Similarly, after complex variable easterly and southerly ice flow during the early Dimlington, there was weak northerly ice flow in the later phase over Birkbeck Fells Common before ice thinned and retreated from Grayrigg Forest. An extensive ice stream, fed by ice emanating from an ice dispersal centre in the eastern Lake District, occupied the large trough of Borrowdale that transverses the southern Shap Fells, but its extension and recession dynamics remain enigmatic.

“Glacial Theory …, in its application to the transport of blocks across Stainmoor, involves such obvious mechanical absurdities that the author considers it totally unworthy of the attention of the Society.” William Hopkins, 1842

Lune 峡谷和 Shap Fells 南部的高地是了解英格兰北部晚德文世冰川 (Dimlington Stadial) 动力学的关键区域。在这里，来自苏格兰南部、湖区和 Howgill Fells 的冰块在 Lune 山谷上游地区相互作用。冰川地貌被记录下来并被记录下来。Shap 花岗岩 (Sg) 漂移物的散布模式被绘制成图，因为这些碎屑是区域冰运动和局部冰动力学的重要示踪剂。这一新信息与现有文献相结合，以提供对复杂冰流历史区域中冰动力学的理解。特别是，已经定义了西奔宁山脉和南沙普费尔斯地区的冰流相互作用。

Lune 山谷上游附近的早期 Dimlington 冰流呈东风。后来，区域重要的东西向冰分水岭的位置向北移动导致向南的基础冰流的地形转向，导致西部冰流（Mint Sg 羽流）和东部冰流（Lune Sg 羽流）的发展); 都绕着沙普瀑布南部的地块向南流动。当时，Shap Fells 南部 Grayrigg 地块最高山脊上的基底冰向南流动相对较弱。西部的溪流延伸到兰开夏郡低地，而东部的冰流在 Lune Gorge 中被来自 Borrowdale 的冰块阻碍，这迫使北部的冰流到 Lune Gorge 的东侧，在那里它被向西流动的 Howgill 冰块阻挡；

在丁明顿晚期，Mint 山谷和南部 Shap Fells 的冰块大部分变薄并向北和向西退缩，上 Lune 山谷内的北冰运动激增，但并未覆盖西奔宁山脉。奔宁山脉西缘（Crosby Ravensworth Fell Gaythorne Plain）很好地说明了当地的冰动力学，那里不稳定的分布反映了当地晚西向东的弱向下消融冰流和冰下融水排水通道的存在。然而，冰最终在 Crosby Ravensworth Fell原地腐烂盖索恩平原。类似地，在早期的丁明顿发生复杂多变的东风和南风冰流之后，在冰变薄并从格雷里格森林退缩之前，伯克贝克山上空的后期出现了微弱的北风冰流。一条广泛的冰流，由东部湖区的冰分散中心发出的冰供给，占据了横穿沙普费尔斯南部的 Borrowdale 大槽，但它的延伸和衰退动态仍然是个谜。
