Pretty devastating They are saying its EHD http://www.youtube.com/watch?v=Z3hWMyNYhBA&feature=player_embedded#t=10
I don't think ehd could happen that fast. Maybe they got into something that was toxic that killed them so fast?
That's like same person winning the lottery in every state on the same day.I wouldn't discount the EHD . They probably all were in the same cloud of nats and all contracted it at the same time and died about the same time.
Its not spread to humans but hunters should avoid killing elk that looks sick.... hugh?
