Build a Life-Saving Fire Bed

[1] Scrape out a trench in the dirt about a foot wide and 8 inches deep. Line it with very dry, egg-to fist-size stones (wet rocks from a stream or lake can explode when heated).

[2] Next, burn a fire down to coals and spread a layer throughout the trench. Cover this with at least 4 inches of dirt and tamp it down with your boot. Wait one hour. If the ground warms in less than an hour, add more dirt.

[3] Check the area twice for any loose coals that could ignite a makeshift mattress. Then spread out a groundsheet of canvas, plastic, or spare clothing. Pine needles or evergreen boughs will work in a pinch.

[4] Ease onto your fire bed and snooze away.
