Coefficient of Friction on Bowscale Fell

 

We dropped off the end of the east ridge of Bowscale Fell. The ridge itself is a splendid high level walk and easy underfoot. The drop into Mungrisdale would be easier up than down.
I experimented with foot placement. Digging in a heel didn't work. Although the pressure would be higher, the torque as I moved forward meant that it was impossible to stay on the heel. The whole foot rotated.
I then started placing my foot down parallel to the slope. I was carefully to come down normal to the surface. Friction force = coefficient of friction x normal force so I hoped to maximise the friction to avoid sliding. Done slowly, it seemed to work.
