Dr Peter Wilson, Ulster University
Itinerary: Initially a flat valley-floor walk of c.1 km from Gatesgarth Farm to Horse Close alongside Buttermere. Then a steep grassy slope up into Burtness Comb (c. 1 km and c. 400 m ascent). Once in the Comb the terrain becomes increasingly bouldery. The nature and source of the rock avalanche debris will be discussed and recently obtained surface exposure ages will be presented. Other features of geomorphological interest will also be discussed.
The rock avalanche is described in the following papers:
