May 7, 1887 Saturday,

Negaunee - During the winter the ore hoisted from pits seven
and eight of the Jackson mine, were stacked near the DSS&A main
line. A wall was built of the heavier chunks and braces were
used, but some snow or ice must have packed into the wall, for
Wednesday morning the stockpile caved outward on to the South
Shore main line and the C&NW Spur. Some of the early ore trains
on the DSS&A were necessarily detained unti the ore was removed
and the work of loading cars was hindered. Otherwise no damage
was caued by the fall.of ore.
