During the last ten years several studies have been published in which numerical ages relating to the deglaciation of Cumbria are reported. Some of these studies were summarised in an earlier paper in these Proceedings (Wilson, 2014) and elsewhere (Wilson & Lord, 2014). Since that time, other ages have been obtained and provide additional insights into the timing of the loss of glacial ice cover in different parts of the county. Some of the recently acquired ages suggest that previous ones, about which an element of doubt had existed because they were single ages from scattered sites, can now be considered as accurate. Together these ages allow statements concerning deglaciation of Lake District valleys to be made with a greater degree of confidence (Wilson et al., 2018). Other recently obtained ages from the coastal/upland fringe of west Cumbria (Chiverrell et al., 2018) give an indication of the timing of land emergence from beneath the Irish Sea/Lake District sector of the last ice sheet and the age of the Scottish Readvance. Additional numerical ages pertaining to deglaciation are now available from Talkin Tarn, near Brampton (Livingstone et al., 2015), and from the bottom sediments of Windermere (Avery et al., 2019).
