How to build a shelter if trapped in wilderness

Spruce
You can usually find a good lean-to site at the base of a tall spruce with large overhanging boughs. The ground near the base of the spruce is often spongy, drier in rain or freer of snow in the winter.
Place spruce boughs over the poles in an emergency, otherwise use plastic or tarps. There should be one step from bed to fire. There should be two trees to hold up the ridgepole which is tied onto the two trees. The ridgepole holds up branches that make a wall. The ridgepole should be shoulder high off the ground.
Prepare to be a wilderness survivor.
