We'd like to send a big THANK YOU to extreme explorer Mark Wood for sharing with us his expedition to Mount Everest.  It has been fabulous to be able to follow his journey up to the top of the world and we look forward to our next Skype in the Classroom call with Mark once he's back in England.  To climb to the summit of Mt Everest is one of the most grueling expeditions in the world and we are glad to hear that Mark made the smart decision to return to safety when conditions proved too dangerous for his team as they made their final approach to the summit.
