Jordan Jonas describes a wet-weather fire method built around locating wood whose interior has stayed dry. Instead of relying on wet fallen timber, find a dead standing tree, fell it, and split it repeatedly until the protected heartwood is exposed. Create a clean edge, then shave paper-thin curls while leaving them attached as a dense bundle. Protect that work from ongoing rain with a quick tripod and tarp. A ferro rod can ignite the finest curls; once they catch, add rougher curls and progressively larger fuel. The mechanism is staged moisture control: select protected material, expose its dry core, maximize ignitable surface area, keep it sheltered, and only then scale the flame.
Origin
Jordan demonstrated the method during a torrential Montana downpour after Tim Ferriss and a friend became cold and lost hand dexterity. Extracted from The Tim Ferriss Show.
Core principles
- 01Dead standing wood protects a dry interior
- 02Fine attached curls catch sparks more reliably
- 03Shelter the ignition area before exposing tinder
- 04Build from fine curls to rougher fuel in stages
How to run it
- 1
Select standing deadwood
Find a dead tree that remains standing rather than wood that has lain on wet ground and absorbed moisture.
Pro tip Expect fallen wood to be especially wet after a winter of moisture exposure.
Watch out Assess the tree and felling area before using an axe.
- 2
Expose the dry core
Fell the tree, split it, remove a smaller central piece, and split that piece again until dry interior surfaces are exposed.
Pro tip Create a clean edge that is easy to shave.
Watch out Use safe splitting technique and control the axe throughout.
- 3
Shave attached curls
Run a sharp axe down the dry edge to form fine, paper-thin curls. Leave the curls connected so they remain in one concentrated bundle.
Pro tip Practice the fine motor control before depending on it in an emergency.
Watch out A sharp axe is dangerous without practiced control.

Shelter the tinder
Build a quick tripod, drape a tarp over it, and work beneath the cover so the prepared curls do not become soaked.
Pro tip Protect the curls throughout preparation, not only at ignition.
- 5
Ignite and scale
Use a ferro rod to spark the finest curls, then add rougher curls and larger fuel after the flame establishes itself.
Pro tip Move through fuel sizes progressively rather than smothering the first flame.
In the wild
During a heavy downpour in Montana, the group became wet and cold enough to struggle with their jacket zippers. Jordan found dead standing wood, split down to its dry center, made attached curls, and sheltered the ignition area beneath a tarp. A ferro rod lit the prepared wood, allowing the group to warm their hands.
→ The group established a warming fire despite saturated conditions.
Common mistakes
Starting with fallen wood
Wood on the ground may have absorbed extensive moisture, even when it appears dead.
Detaching every curl
Loose curls are harder to keep concentrated and protected than an attached bundle.
Preparing tinder in open rain
Fine curls can be soaked before the spark reaches them, undoing the preparation.
Is it for you?
Best for
It is best for trained axe users who need warmth in sustained wet wilderness conditions.
Not ideal for
It is not ideal for beginners without safe axe control or access to dead standing timber.
From the transcript
“chop down a dead standing tree because it, you know, you might see dead trees on the ground, but it's amazing, particularly in the spring…”
“And once you got it split open, you're to that dry wood, and it never gets wet because it was standing.”
“we made a quick tripod, draped a tarp over it, and tucked under that to actually build our fire.”
