Signs of a Pica? I heard the tell-tale ‘eeep!’ of this small member of the rabbit family, but did not catch a glimpse.

Picas dry out plants on rocks in the summer so they’ll keep better for the winter. Clever. See the Lousewort (Pedicularis) tips drying in the sun?

Some kind of lichen. Anyone? Lichen are fungus and algae living together in a symbiotic relationship. I have really simplified that. Sorry lichenologists!

Up in the mountains there are many different species of lichens growing on rocks too. How to remember what lichens are: Freddy Fungus and Alice Alga got married, and now their marriage is on the rocks. (Again, apologies, bad naturalist joke).

I couldn’t stop taking pictures of this rock. The lichen colour was so beautiful.

Someone’s droppings. Ptarmigan?
