Why a cairn at a desk
A hiker not on a river still wants the clack of wet stone. The current is a slider, not weather. Balance is the job.
How the stack is tested
Each stone adds lean. Current adds more. Past a limit the pile settles into the water. Rebuild clears it without a score.
How to use it
Add stone. Raise current if the hold feels too easy. Rebuild after a fall. Water hush is optional. Not trail advice.

Cairn FAQs
How do I stack the cairn?
Tap Add stone. Each stone sits a little off center. Current leans the tower. If lean grows too far the stack eases down. Rebuild starts again.
Is a fall a fail?
No. The fall is gentle. Rebuild is part of the session.
Does this teach hiking safety?
No. Desk stones and a chosen current only. Not trail advice.
