The worst flood in Southern Arizona in a quarter of a century washed away homes, livestock, and bridges including the bridge at Amado on the access road to the Smithsonian's Mt. Hopkins Observatory. Several Smithsonian astronomers were trapped on the east side of the Santa Cruz River for two days by the rapidly flowing waters. Later, a makeshift boatswain chair, fashioned from ropes, pulleys, and an old auto tire, was strung between the banks to rescue the stranded.
