I assume that you have a large bore sidearm or a rifle.

If you RON away from camp select a suitable tree or rock to
lean back against, clear all combustibles from the ground for
ten feet in all directions, insulate your butt from the
ground, put on liner with poncho, and put lighted candle lantern
on a stick across a hole between your feet. Heat will rise inside
the poncho. The Hilton it aint but it'll keep you alive.

NOTE as soon as you realize that you are lost sit down, thinks
things over, check your map, take a drink of water, eat if you are
hungry. Relax. If it is late afternoon expect to RON there.
