Dig the spring deeper to allow you to fill larger vessels for drinking, cooking, etc. In autumn, rake up leaves if you are in a deciduous forest. In winter cut evergreen boughs and pile to a height of at least one foot. The point is to keep you off cold or wet ground. Morning damp and cold collects in valleys.
Wind is more likely on a ridge.
In summer, the point of land jutting into a lake is more likely to have a breeze which will keep bugs away and keep you cool. Take some time deciding the best site for your fire if it needs to be sheltered. Decide what your fire is for. Roasting takes a very small fire. Boiling needs a larger fire.
