The X’s all around Red House, Quaker and Science Lakes are rescue devices should someone fall through the ice. The attached rope is for a rescuer to hold onto while the boards slid out to help dissipate the weight of someone as they get out of the ice they’ve fallen through. Hopefully, they will never have to be used but now you know just in case. Should you see any of these X’s lying flat, please help out the park and prop them back up on the metal poles to which they should be loosely attached.
