WASHINGTON – President Barack Obama shared a photo he took in Argentina on his Facebook account Friday.
Obama said he, First Lady Michelle Obama and their daughters, Malia and Sasha, hiked through Patagonia, the southern end of South America's Andes mountains.

"We walked paths along glacial lakes surrounded by snow-capped mountains," Obama said.
Obama said the scene motivated him to continue his efforts against climate change, warming that NASA scientists say happens when the atmosphere traps heat radiating from the Earth toward space.
"It's the only planet we've got and it's spectacular, so let's take good care of it," Obama said.
After a historic visit to Cuba and Argentina, Obama landed at Joint Base Andrews outside of Washington, D.C., on Friday morning. Obama also visited a memorial park honoring the victims of the "Dirty War" with the country's newly elected president, Mauricio Macri.
