The trap

Trap. U-V (carnotite, tyuyamunite, coffinite) on carbon trash in channels. Uravan, Grants, Lisbon.

Wrong mountain
Do not call every yellow sandstone 'Silver Reef.' Salt Wash is uranium country. Silver is not the vector.

- Host is Springdale — Play A.
- No Morrison / Salt Wash channel.
How to use the score
The score orders the day. It is a walk sort. It is not an assay, a mining claim, or permission to enter. Killed ground stays on the map so the boundary is visible. Private land, tribal land, and park interiors stay off the walk.
