Take notes daily on the object's changes under different conditions.
Based on the notes and observations and additional reading from Britannica Encyclopedia (pp 798), analyze and draw conclusions.
First of all the 'object' looks like a pumpkin (half of it is rotten too). It has lost its rind except at the bottom and right now it is light orange.
Second, a real pumpkin can be stored for a few months in a dry place well above freezing temperature. This point coincides by looking at the surface of the McGraw-Tower pumpkin towards Olin since this side is lightly furrowed and ribbed and well preserved for it is facing south and therefore in dry condition. Just the opposite, the side facing north has already sank down and lost its roundness. It has black spots for it is rotten and fermented because this side facing north gets less sun and warmth and therefore not in very dry condition.
Third, either rain or snow, the amount of water that can be accumulated at the top can not be much because it is only a small area. Therefore even though this pumpkin has stayed up there all this time, half of it is still round and preserved its shape.
