Snuck by Aconcagua

At nearly 23,000′ Aconcagua is the tallest mountain in the Western Hemisphere. It was a clear blue day and we flew right next to it crossing the Andes back into Chile.

They did, nonetheless, turn the fasten seatbelt sign on. Evidently it is SOP for LATAM when crossing those hills.

Alas, no photo. The guy at the window seat kept the shade down.
