For those of us predisposed to these occurences, even a small particle
hitting just the wrong spot can trigger one. I had a tortilla chip
cause one once, as did some red pepper on a sandwich bun. Not fun at
all. I even have had one trigerred once by chomping on some ice. So,
to answer the OP's question, YES, it is possible to "drown" in snow,
but it is much more likely that you'd suffocate.

Some kid took a header off the traverse below the Casper Resraunt the other
day. According to the JH Ski Patrol, the kid had a big wad of chew in his
mouth. It lodged in his airway. His buddys got right to him and called
the Patrol. Unfortunately they weren't trained and neglected to clear
his airway. He was pretty much dead meat by the time the Patrol got to
him, but they revived him. He had severe brain damage from suffocation
and died in a hospital shortly afterward.

So I can see asphyxiation and suffocation, but by your very denotation
of dry drowning, one must first inhale water. Without the inhalation of
water, there is no drowning. Good research.
