From 5 Foot 10 to a Lump of Good o' Rock.....Help Please! A Good O' Rock

Samuel was your average Community College student, about 200 pounds and 5 foot 10. Average grades, average effort. Of Course that was till he tripped while hiking into crevasse, though a oddly smooth shoot to a patch of (Mostly) dormant lava. Next he knows is that he can't see, hear, move, or breath, or that he even needs to breath. After a very long time....."I'm I a rock?"
