Where: Mexico · North America · approx. 25.79, -103.79 (vicinity only)

Why this spot: Rockhounding locality: ghost mining camp above Mapimi whose 1898 Roebling suspension bridge leads to the Ojuela mine, world standard for adamite and legrandite with 117 recorded species

What turns up: adamite, legrandite, hemimorphite, wulfenite and aurichalcite from on-site vendors, ruins of the camp

Access: Licensed / permit.

Visited as a paid attraction: small entry fee for the bridge and guided mine walk; the underground and dumps are worked by local miners, so buy from the vendors at the bridge rather than hammering the dumps yourself
