The North Face/NatGeo Everest team is now climbing the last leg of the ascent of the highest peak in the world. They left camp 4...and are estimated to summit about 7 pm Central Time tonight. Check out the latest from writer Mark Jenkins at the NatGeo blog. All are wearing monitors that are recording their position and a range of vital signs that will be added to the data already collected by the Mayo Clinic research team. Our best to Conrad Anker and his team in their final ascent.
