Read the Slope: Flat Is Not the Same as Level
Perfectly flat ground looks inviting and is often the worst choice. Water has to go somewhere, and flat ground in a low position is where it goes to sleep.
A gentle grade — enough that water moves past you, not enough that you slide downhill in your sleep.
A slight grade sheds water. A bowl, hollow, or dead-flat basin collects it — a puddle waiting for weather.
Pick the mild slope and lay your sleeping area across it, head slightly uphill.
Kneel and sight along the ground. Slope you can't see standing up becomes obvious at eye level.
Choosing a spot for its comfort in dry weather. Ask what that ground looks like after four hours of rain, then choose.
Follow the Water: Drainage, Runnels, and Old Flood Lines
Water leaves a record. Learn to read it and you won't be flooded out.
Shallow channels and runnels cut into the soil, even dry ones. Fans of leaves, twigs, and silt deposited in a line.
Everything you see was carried by water at some point, and will use the same path again.
Get above and outside every channel you can identify. Give yourself margin.
Debris lodged waist-high on a tree trunk is a flood line, not decoration.
Camping in a dry wash or gully because it's sheltered and sandy. Those are the most comfortable-looking hazards in the backcountry — a storm miles away can send water down them under a clear sky.
Feel the Wind: Channels, Gaps, and Exposed Shoulders
Wind steals heat faster than cold air alone ever will. Reading where it runs is half of staying warm.
The shape of the land funnels wind the same way it funnels water — saddles, gaps, and open shoulders.
Gaps and draws accelerate air. A ridgeline or exposed shoulder gives you a view, and takes your warmth.
Site yourself on the leeward side of a rise, dense timber, or a solid deadfall.
One-sided tree crowns and branches trailing in a single direction record the prevailing wind for you.
Judging wind by the hour you arrive. Evening calm is unreliable — the wind that matters often arrives after dark.
Cold Pockets: Why the Valley Floor Is the Coldest Bed You Can Choose
Cold air behaves like water. It is heavier than warm air, it flows downhill, and it pools in the lowest ground it can find.
Hollows, basins, valley bottoms, and flat ground beside a creek.
On a clear, calm night, cold air drains off the slopes and settles low — the bottom can run substantially colder.
Sleep partway up the slope — on a bench, below the ridgeline, above the valley floor.
Heavy dew, lingering frost, and low-settling mist mark exactly where cold air collects.
Camping right beside water for convenience. The streamside flat is usually the coldest, dampest ground in the whole drainage.
If a site fails one sign badly, walk on. There is almost always better ground within a few minutes' walk, and the ground you choose does more work for you than anything you build.
Building where you stopped walking instead of where you surveyed. Fatigue picks bad ground — give yourself fifteen minutes to loop the area before committing.
Look first. Test small. Act only after the sign is clear.
