Make it step by step
- Step 01
Select flat-topped stones without loose layers. Set them on firm level ground; reject any that rock or crumble.
- Step 02
Arrange a triangle with all three supports underneath the container's bottom, leaving the centre open.
- Step 03
Lower the empty container carefully. Press lightly around the rim. Replace a mismatched stone instead of stacking tiny shims.
- Step 04
Add cool contents gradually, keeping the weight central and handles away from walkways.
Check before use
The base contacts all three supports and gentle rim pressure does not tip it.
Limits of this project
Not a stove or cooking support. Do not put hot cookware on unknown stones.
Take down and restore
Remove the container, clear food scraps and restore stones without leaving cairns.
All lashings and racks here are for light objects, never people, climbing or rescue.
