Museo Geominero

This guide to the Museo Geominero in Madrid opens with a farming family near Retuerta del Bullaque, who spent thirty years using a suitcase-sized chunk of iron to press hams, assuming it was old military scrap pulled from a field. It follows geologist Juan Carlos Gutierrez Marco, who heard about the strange iron block still doing kitchen duty and asked to examine it. Find the case holding a fragment of that rock beneath the museum's stained-glass roof, raised for a king in 1926, among some fifty other specimens pulled from deserts and fields worldwide.
