Mariscal Mine, Mercury mine in Big Bend National Park, United States.

Description

Mariscal Mine is a cinnabar extraction site in Big Bend National Park containing substantial ruins of industrial structures like storage bins, a furnace, condensing chambers, and a prominent brick chimney set against the desert. The stone and brick structures remain largely intact and display how the refining process operated.

History

Operating from 1900 to 1943, this cinnabar mine produced around 1,400 flasks of mercury that represented roughly one quarter of total US mercury output during that era. The operation was a significant source of raw materials for the nation throughout those decades.

Culture

Mexican workers made up the main labor force here, building their own shelters from rocks and brush while earning minimal wages for grueling daily shifts.

Practical

Access via River Road East requires high-clearance vehicles since the route is rough and challenging to drive. Visitors should exercise caution around abandoned structures and stay away from open mine shafts.

Did you know?

The processing at this site relied on a custom Scott Furnace built from local clay that extracted mercury from cinnabar through a vaporization and condensation method. This technique was notably efficient for its time.
