TODAY'S FUN FACT

 

The early derricks in the quarry were made of wood and run by horse and steam power.  American Hoist and Derrick Co. of St Paul built and installed many of the approximately 100-foot derricks.  A few of the later derricks installed were steel.  Each mast had about eight guy wires running in all directions secured in the rock to anchor and stabilize it.  Some guys wires were anchored on the other side of the river.  The hinged beams attached to the masts that lifted and guided the mill blocks were called booms.




The sandstone History Center began a project to restore and preserve the last guy derrick mast in Robinson Park during Sandstone's Centennial Year.
