If those are true so there's simply a plug, you might since you have the
top open try either a piece of 3/8" or such rod w/ a pointy end and see
if can break thru physically the ice layer. Or, assuming the 1-1/4"
standpipe or similar, a half or 3/4" piece of pipe ought to work, too.

Iff'en it's not too thick of a block, that might well be enough w/ a few
love taps...
