Pole and Bough Lean-to One of the most ancient shelters, the single wall of a lean-to serves triple duty as windbreak, fire reflector, and overhead shelter.
Step One Wedge a ridgepole into the crotches of closely growing trees (one end can rest on the ground if necessary), or support each end of the ridgepole with a tripod of upright poles lashed together near the top.
Step Two Tilt poles against the ridgepole to make a framework. To strengthen this, lace limber boughs through the poles at right angles.
Step Three Thatch the lean-to with slabs of bark or leafy or pine-needle branches, weaving them into the framework. Chink with sod, moss, or snow to further Â¿Â¿insulate.
