A rock on ice, what will happen?

I have a rock 5' long, 2' wide and 10" thick, more or less. It is semi-rectangular. I have been wanting for a couple of years to put it in the edge of the pond but I needed to put some 4-6" high rocks under the "downhill" side to keep it level. I couldn't figure out how to move the big rock into the pond without it pushing the little rocks out of place ahead of it. I had a brilliant idea around Christmas when we had bare ground and the ice melted in the pond. I put the small rocks in place and marked outside them with some 1x1x48 oak stickers from the sawmill hammered into the pond bottom. A few weeks later when the pond was frozen hard and we had a foot of snow I took the Farmall 300 over there and dragged the rock the last distance to the pond and then got behind it and pushed it out on the ice, up to the stakes. My idea is that when the ice melts the rock will lower itself into place on top of the smaller rocks on one side and the pond bottom on the other, but I have never done this before and I do not know if it will work. When the ice starts to melt should I chop the part under the rock off from the rest with an ax or leave it attached to the whole rest of the pond? Any advice will be much appreciated.

It should start sinking into the ice slowly from the weight of the rock melting the ice under pressure.

Sounds like a good enough plan so far. I'd stay away from it and let nature take it's coarse from here on out. I'd hate to be near it if something went wrong !

With enough sunshine,the rock should heat up and the ice will melt around it sooner than the rest of the ice will melt anyway.

I would leave it alone as the ice usually melts around the edges of the pond first.That would let it settle into place.

The DNR build a lot of rock reefs on the lakes around here in the winter. They drive the trucks out on the ice and pile the rocks and in the spring they melt through the ice and form the reef on bottom. Seems to work pretty good.

You might tether it so it doesn't slide away from the bank if it goes down uneven.
