Warsaw Advanced Shelters 
Nov. 2003

The challenge was to build shelter for a Patrol which would maximize protection and warmth.

Saws and axes were allowed to speed up the process
but the lessons learned can easily be generalized to a survival situation.

We used downed lumber.  No trees were cut. There was no shortage of fallen poles.

Green boughs were collected from the ground where they had been blown from trees. 
Boughs from several freshly cut trees out by the road were also collected and used.

The result was a cozy and warm shelter. 
Hot rocks were brought in to provide warmth on the sub-zero night, but weren't that necessary.
