Roughly what share of the world's discovered boxwork formations are found in Wind Cave?

The honeycomb of thin mineral fins was first noted here.

Boxwork is made of thin intersecting blades of which mineral?

The fins once filled cracks in the rock; the softer bedrock around them dissolved away and left them standing proud.

A huge cave with only a few small openings breathes far more obviously than a small cave with many mouths.

His work was so thorough that no major new passages were found until 1963, seventy years after he died.

Three levels of passages are packed into the upper 76 metres of one limestone layer.

Which limestone, laid down in a Mississippian inland sea, holds the cave's three levels?

Red sands and clays of an overlying formation later filled many of the early cavities.
