The Yorkshire Dales are pocked by deep scars: chasms eroded out from beneath the limestone by running water. There is an excitement in this landscape in which springs erupt unexpectedly out of rock, run a distance and descend again into dark sinks. Everywhere, my walking was accompanied by sounds of accumulating snow-melt: gurgling, rushing and roaring. I purposely planned my route to paint at two deep pot holes.
The day was accompanied by drizzle veering into snow. I set up to draw in these conditions using a large sheet of heavy textured watercolour paper folded into sixteen panels that would slide into a plastic protection. I decided to experiment with soluble graphite and inktense watercolour pencils. This way, I could snatch brief interludes in the weather, use the drizzle itself or ground water, and work with limited materials I could hold in my pockets.
This proved tricky. I could indeed work into the snow-dampened paper and the falling flakes or drops added to the texture. However, I had to work for just a minute or two or the whole thing would wash off. Drying in my pocket, the adjacent surface lifted some of the pigments though also added to the textures. This then was the first sketch.
Only later, with the paper thoroughly dried, did I work again into this with conti crayon, watercolour and knife to create the image I wanted.
I am editing this post in response to a comment below to add links to my use of this folded paper approach, in case you are interested.
