More Volcanics in the Lake District - The Haystacks

After writing about my fortuitous find at the Langdale Pikes, it brought back memories of several trips to the Haystacks. Of which many were performed in the howling wind and rain, not uncommon for the Lake District. On one very memorable day I was helping a friend with his dissertation fieldwork and the wind was so strong that at one point he actually had to catch me to stop me blowing away! Suffice to say we didnt spend too much more time on the hill.
 
Anyhow, the Haystacks (pictured below) are another part of the Borrowdale volcanics and make for a very interesting walk (on a good day you can see Scafell Pike and Great Gable for example). In the area are a number of volcanic features including pyroclastic tuff deposits at an area called little round how (if I remember correctly) and the site of a pepperitic contact (something I shall discuss in a later post). One of the most intriguing deposits is littered across the summit of the haystacks itself and can be described as a series of andesitic folds which are thought to have been part of a doming formation. Although detailed research has yet to be completed, to my knowledge anyway. These folds are pictured in the image above where the banding of the folds can be clearly seen.
