Find a cave to hunker down in for the night

Wanting to avoid the wind and rain that seems to be approaching the mountain slope you duck into the trees and start searching for shelter. After several hours the rain begins to pour and the tree cover stops you from being soaked for a while but as the dark sets in the storm intensifies. Soon your clothes are soaked through and a chill sets in.

Growing increasingly **** you slip on some rocks and take a tumble, sliding down a short but steep drop. You're ok, some superficial gashes that need dressing but you've done worse to yourself playing sports. That tumble may have been great luck though looking up you see what you fell into. The short drop was into a small gully in the hill leading to a mostly hidden cave opening, you can shelter there while the rain dies down.

Gathering your things you get to the cave opening and set your things out of the rain. Lighting a small lamp you set to seeing the bounds of this cavern. Its seems like maybe a roughly 20 by 20 meter space low light and you are **** to duck in several spots but its generally flat. You could put out your bedroll here easily and maybe wait for morning.
