Friday Photo (119) – Pacaya Lava Store, Guatemala
Lava Store, Pacaya Volcano, Guatemala An entrepreneurial Guatemalan sets up a lava store next to Pacaya (my understanding is that they sold products made from the lava, not just pieces of it – which are in abundance in the area!). This store was destroyed by the 2nd March 2014 lava flow. (Credit: Joel Gill, February 2014)
