Where Fairies Dance

This is Ashgill Falls, near Alston, Cumbria, in very quiet mood. You can walk behind the waterfall, and its said that fairies can be seen dancing in the spray.
I wonder if these students saw any. After walking behind the fall they were encouraged (with much chanting and primal noises) to stand under the water. It's not normally safe to do that but as we've had very little rainfall this year, I think they all survived.
