That's right, not bumps or lumps...humps. How do I avoid these buggers??
We had some warm weather the last two days, with highs in the mid 30s, and a bit of rain. This of course softened up the ice a bit. By yesterday it looked like a fairly flat, semi watery surface on the rink.
Then it got cold again last night. This morning my surface is certainly skatable, but has a bunch of small (1 to 5 or so inches across) humps on it! What the heck!
I gather that these are caused by the surface water freezing and then the water below freezing, expanding up and out and creating a "boil" or a "zit" type feature on the topography of my slab. True, they are easy enough to get rid of with a short skate and a resurfacing...but is there any way to avoid them entirely?
I get these occasionally when I flood. I can't figure out if it is correlated to air temp, water temp, moon phase, etc?
Any ideas out there?
