Deadman Anchors, Part 1

Summary:

This video introduces dead man anchor construction, a technique for burying objects (rocks or logs) to create anchors in locations where natural features don't exist. Originally developed for military applications like extracting stuck vehicles from mud or sand.

Construction Steps:

1. Excavation Design:

• Dig main hole for the anchor object (rock or log)

• Dig perpendicular exit trench where webbing will run to the surface

• Exit trench points in the direction of the anticipated load

2. Rock Selection (Two Critical Criteria):

• Flat surface: Must push against the hole wall in the direction of loading

• Shape: Should help keep webbing secured in place

3. Webbing Attachment:

• Tie overhand knot on a bight in webbing

• Pull remaining webbing through loop to form girth hitch

• Girth hitch works well because it cinches down on the buried rock

4. Backfilling Technique:

• Add dirt, tamp to compress

• Repeat: add more dirt, tamp again

• Continue until hole is completely filled

• Goal: Maximum compression of soil

5. Adding Mass (Critical for Strength):

• Mark the spot where girth hitch exits bottom of buried rock

• Stack additional rocks directly above and in front of buried rock

• Added mass dramatically increases anchor strength

• Focus weight placement over the exit point

Real-World Test: Two people (including "strong young stud" Austin) pulled hard on the completed anchor—it held solidly.

Important Caveat: This demonstration was conducted in nearly ideal conditions (good soil, proper compaction, adequate mass). Performance varies significantly based on soil type, moisture, compaction quality, and rock selection.

Series Note: This is part of a multi-video series on dead man and cairn anchors, including proper sequencing and testing protocols (covered in subsequent videos).
