While digging myself out of last night's snow I got a call about this.
The stuff my nightmares are made off
Because it does this to the inside of the house
Two hours of beating on it with axes, picks and sundry sordid implements of destruction got us this far. See the channel we cut in the left side. (click on the picture to embigen) When we opened it up we drained about 50 gallons of melt water that were dammed up behind the ice. As soon as we drained it off the dripping inside the house subsided.
Five hours of beating on it and a pile of aching bones saw most of it gone.
Three more valleys look the same. Hope they don't cause more problems because they are not quite as easy to reach.
