terrible!!!!
Now there's your problem!
To bad it was such a serious issue but now it can be rebuilt and any issues addressed so it will be good as new!
Thanks for posting the outcome, helps everyone else in their problem diagnosis.

and the contributing factors to a broken skirt?
in no particular order of importance:
1. poor fuel(detonation)
2. engine air leak
3. engine mods
4. lean jetting
5. water/snow ingestion through the intake
make sure and find the root cause. dont just slap a new piston in and go. others may add to the cause list as well, those just came to mind.

clutch side check for torn crank seal
actually that happens from too much skirt to wall clearance, in lamens terms the rings are let go too long, pistons wear the the skirts from rocking back and forth in cylinders,and the skirts break off. The intake side is the thrust side of the piston, almost always break on the intake.
How could a torn crank seal blow a piston?
IMO...this engine should be pulled right appart and inspected/repaired after that kind of damage and metal fragments that would be in the crankcase.
Any thing that can cause an engine or cylinder to run lean can cause piston/cylinder damage from too high of piston/cylinder combustion temps.
A leaking crankcase seal allows air to be pulled into the engines crankcase and creates an imballance in your fuel mixtue...too much air to fuel = too lean = too high piston/cylinder temps = melted piston!
In this case, from looking at the pictures, I agree with mrviper700 that the majority of damage was caused by a broken piston skirt which is usually a result of too much clearance. Its time for a complete rebuild.
