Glen Croe, located near the western edge of the Loch Lomond and Trossachs National Park, is a well-known landslide hazard site in Scotland. Debris flows have repeatedly closed the A83 Rest and be Thankful road that passes through the valley, and considerable investment has been directed towards hazard risk reduction. However, little research has focused on the former glaciation and paraglacial response that have played an important role in governing current landscape processes at the site. This paper addresses the knowledge gap by investigating the glacial processes that have shaped and conditioned Glen Croe, and pathways that have characterised subsequent paraglacial sediment transfer. The large-scale valley form results from watershed breaching and interaction between glacier erosion and paraglacial rock slope failures. The distribution of thick glacigenic sediment is conditioned by deposition at former lateral ice margins, which was influenced by topography. Sediment reworking has resulted in accumulation of debris cones and alluvial fans in the upper part of the catchment, and growth of a delta at the outlet. Spatial connectivity mapping supports an interpretation whereby upper Glen Croe is poorly connected to the valley outlet, influencing sediment storage. In contrast, slopes in the lower part of Glen Croe are well connected. Sediment distribution in Glen Croe fits within the context of glaciated valley and paraglacial landsystems, allowing an understanding of sources and transport pathways. In upland infrastructure corridors this type of information is potentially helpful for understanding how landscapes might be affected by renewed sediment reworking under altered threshold conditions.

格伦·克鲁（Glen Croe）位于洛蒙德湖和特罗萨克斯山国家公园的西边缘附近，是苏格兰著名的滑坡灾害场所。泥石流多次关闭了穿过山谷的A83休息区和感恩之路，并且已经投入大量资金用于减少灾害风险。但是，很少有研究集中在以前的冰川作用和冰期响应上，这些作用在控制该地区当前的景观过程中发挥了重要作用。本文通过研究塑造并调节了格伦克罗（Glen Croe）的冰川过程以及表征随后冰期沉积物转移的途径来解决知识鸿沟。大规模的山谷形式是由于流域破坏以及冰川侵蚀与冰川下岩石边坡破坏之间的相互作用而产生的。浓厚的冰川成因沉积物的分布受沉积物在前侧冰边缘的影响，这受地形影响。沉积物的修复导致集水盆上部堆积了碎屑锥体和冲积扇，并在出口处形成了三角洲。空间连通性映射支持一种解释，即上格伦克罗河上游与山谷出口的连接不良，影响了沉积物的存储。相比之下，格伦克鲁（Glen Croe）下部的斜坡连接得很好。Glen Croe的沉积物分布符合冰川谷和冰川下土地系统的背景，使人们能够了解其来源和运输途径。
