Explore possible trail junction

This may or may not be a trail junction between three branches: * Branch going north to the road * Branch going southwest to the hut * Branch going east to the road that's further away I'm not quite sure if the third branch exists. If it does exist, we should explore it and decide whether that branch should be restored. In that case we should also install a sign here in the future to mark the junction and describe what the three branches are.
