Planes sit on the tarmac at Jorge Newbery airport where flights were canceled due to an ash cloud that reached Buenos Aires from the Puyehue-Cordon Caulle volcano in Chile, grounding air travel in Buenos Aires, Argentina, Monday June 13, 2011. The wind carried volcanic ash across the Andes to Argentina resulting in the closing airports and the cancellation of flights in the capital city. The Puyehue-Cordon Caulle volcano, dormant for decades, erupted in south-central Chile on June 4. (AP Photo/Natacha Pisarenko) less
