The trap
Host. Shinarump Member (basal Chinle) channel conglomerate scoured into Moenkopi.
Trap. Uranium-vanadium-copper on organic lag at the channel base. Same Chinle plumbing as Play A; different bed, different metal.
What a hit looks like. Yellow carnotite / green Cu on carbon in a conglomerate channel sitting on red Moenkopi. The channel, not the mesa top.
Wrong mountain
Do not hunt horn silver here as the primary. Cameron was a uranium camp. Silver is a pathfinder on the same trash.
- No Shinarump / basal Chinle channel.
- You are in Salt Wash / Morrison — that is Play D.
- You are in Springdale sandstone reefs — that is Play A.
- Park interior or tribal land without permission.
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.
