another anomily found and have no idea what it is

I found this about 6 months ago and it has done a bit of changing since, when I first found it the very outside was hard as a rock then the middle part was a bit more opaque and then the center was like a digestive track, now the outside is softand a hole has appeared from the middle and the center is getting quite a bit bigger, any ideas? It looks like a cyst, but the rock got moved in an avalanche and I cant get a good pic of it now it is hard to even get a good lok at it. Unless I tip everything over again *(&%^!!!) I am going to have a hard time keeping a good watch on it.
