Step back to a sweltering summer night that forever reshaped Morris County. One hundred years ago this week, lightning from a powerful thunderstorm struck a storehouse of surplus World War I explosives at Lake Denmark, inside Picatinny Arsenal—triggering what is now recognized as one of the worst man-made explosions in American history. Join Jeff Ranu of Picatinny Arsenal’s M.E. Mortars Division for a gripping, behind-the-scenes look at the events leading up to the blast, newly uncovered footage revealing the scale of the destruction, and the far-reaching safety and operational changes that followed. This powerful presentation brings a dramatic and little-known chapter of local history vividly to life.
