T11a - Marrick Smelting Mill
Date : 20/06/2026 Time : 09:15 - 10:15Richard Lamb
Location : NGR SE 04616 98433
Details :
The High and Low smelting mills at Marrick are the best preserved in the country complete with four dams, a complex system of watercourses, an intriguing flue layout plus several ancillary buildings and other features. New endeavours, based on the work of others but applying fresh concepts thanks to comparison of historic maps, lidar and Google Earth images, plus on-site measured surveys has assisted the reinterpretation of several mills .
Ricahards enduring interest in lead smelting mills was fostered by Robert Clough’s seminal book illustrating the buildings encountered during our first visit to the Dales in 1973. This ongoing fascination continued intermittently, later resulting in a lecture at the Boles & Smelt Mills Seminar held in Swaledale in 1992, followed by the publication of the first ‘A Smelting Miscellany’, now up to number six.
Examination of sites mostly in Yorkshire but also in Derbyshire, Shropshire, Co. Durham and Scotland ensued, leading to a study of slag mineralogy culminating in the identification of two compounds new to science. Subsequent part-time employment with a local archaeological company involved many projects within the Dales incorporating both lead and coal mining remains, watercourses and several smelting mills which promoted a greater understanding of the environment in which these buildings once operated. Concurrently, lectures were given in Reeth and field trips organized for interested parties, both on behalf of the Swaledale Museum.

T11d - North Pennine Hushes: myth versus reality
Date : 20/06/2026 Time : 11:30 - 12:20Brian Young
Location : NGR SE 04616 98433
Details :
The voluminous literature covering centuries of Northern Pennine lead mining contains countless references to the practice of ‘hushing’. In simple terms this form of hydraulic mining is generally assumed to have involved the gathering of large volumes of water in specially built reservoirs behind ‘hushing dams’, and its repeated sudden release as powerful erosive torrents intended to expose orebodies, creating the conspicuous gullies known as hushes. It has long been supposed that this was a technique widely employed across the Pennines and elsewhere, both as a means of prospecting for, and the working of, orebodies.
The hushing concept is firmly, but uncritically, embedded in the annals of mining history, together with some curiously elaborate classifications of different types of hush. However, recent detailed geological and geomorphological research has revealed irrefutable evidence that the area’s largest and most conspicuous of these hushes are of entirely natural origin, created by powerful natural erosive torrents of water many millennia before any human occupation. As channels excavated by volumes of glacial meltwater far greater than anything capable of being supplied from a hushing reservoir, somewhat paradoxically, they may reasonably be interpreted as hushes, but they are hushes of wholly natural and pre-human origin. Whereas these findings do not destroy the concept of hushing within mineral working they do indicate the need for a careful evidence-based and realistic approach to the true nature of hushing.
A native on NE England, and graduate of Queen Mary College, University of London, Brians early fascination with local rocks and minerals developed into a long research career with the British Geological Survey (BGS). After starting work investigating the tin deposits of S Thailand, he spent a number of years researching the ‘soft’ rocks of SE England before returning to NE England as a founder member of the BGS Newcastle Office, of which he became Head. He has worked on many aspects of N England geology, though with particular emphasis on the mineral deposits of the Northern Pennines and Lake District. He was privileged to work with the late Sir Kingsley Dunham on the revision of the classic BGS Memoir The geology of the Northern Pennine Orefield Volume 1.
His work on Northern Pennine mineralisation was recognised in 1993 with the naming of brianyoungite, a new mineral discovered in the workings of Brownley Hill Mine, Nenthead, and subsequently reported from numerous other worldwide locations. Since retiring as the BGS District Geologist for Northern England he continues his research as an Honorary Research Fellow in the Department of Earth Sciences, University of Durham. His list of over 200 publications includes scientific papers, books and popular articles. He is especially keen to share his interest and enthusiasm for geology and landscape with a wider public and is a frequent lecturer and leader of excursions.

T12b - History of Lead Mining in Upper Swaledale
Date : 20/06/2026 Time : 14:45 - 15:30Helen Guy
Location : NGR SE 04616 98433
Details :
This talk covers the history of lead mining in Swaledale going back to Roman times. Topics include methods of mining, the roles of women and children in the mines, the lives of miners and their families, and the decline of the industry in the late 1800's and the impact on the population of Swaledale.
Helen is Curator and Project Manager for the Keld Heritage Centre in Upper Swaledale. A registered charity which aims to preserve the heritage and traditions of Swaledale via our Visitor Centre, Old School Museum and our annual events programme which includes guided walks, talks and workshops.

Date : 21/06/2026 Time : 10:15 - 11:00Judy Mitton
Location : NGR SE 04616 98433
Details :
The starting point of Judy Milton’s presentation is a line from a poem – The Watershed: “This land, cut off, will not communicate”. It was written about the northern Pennines lead mining landscape by W.H. Auden in 1927.
Judy’s talk focuses on Swaledale and Arkengarthdale. In it, she argues that the mining landscape speaks volumes; its voice can be heard both above and below the ground. Settlement features, mining techniques and geology all clearly contribute to the dialogue.
The talk is aimed at delegates who are unfamiliar with the area and/ or would like to know more about what they see on their travels, and there’ll be a little bit of Auden’s poetry.
Judy was born and brought up in south Lancashire and has loved the Dales ever since a school Geography trip over 60 years ago. She moved to southern England in the 1980s and is an active member of Kent Geologists Group, the O.U. Geological Society’s S.E. Branch, and Medway u3a. Her book, Lead Mining Land The Northern Pennines (Astride Auden’s Watershed), which was co-written with her daughter Chrissie, has been well-received. Judy and her daughter are donating 1/3rd of Conference sales of the book to Keld Resource Centre, Swaledale.
