Powder box church

When I heard the name, I wondered by powder was associated with a church.  Phrases like "powder room" and "powder my nose" came to mind and didn't understand why the people of this congregation should be known for their powdering habits.

What I should have given more thought to was the two words together and the location.  Powder box.  Mining town.
Oh.
Blasting powder boxes.
Got it.

The Mexican American mining families were not welcome in Jerome's Methodist church, so they built their own from discarded powder boxes, wire mesh and stucco.
Their ingenuity created a very unique and pretty building.
