Sorted patterned ground in the English Lake District

This paper describes sorted stripes at High Pike in the northern English La ke District. They occur at 658 m on a scree with an aspect of 275 degrees a nd slope angle of between 17 and 18 degrees (maximum 19 degrees). Approxima tely 39 coarse stripes occur with an average width of 37 cm. Compared with other Lake District sites, High Pike has well-developed sorting at a relati vely low altitude. A large proportion of frost-susceptible fines, vegetatio n-free scree and an exposed aspect contribute to this. Similarity in form a nd direct observations over short periods (five consecutive years) indicate the stripes at High Pike have remained active since they were first descri bed by Hollingworth over 70 years ago.
