Extreme hiking was on the agenda Wednesday. We transferred by bus on the Pan-American Highway to Cotopaxi National Park. At the park, we hiked a couple of trails to view the active volcano with the same name. Our guide was telling us that the peak has been covered with clouds for the past three week, but the peak was almost in full view at our arrival.
While walking on the trail, Bill's ForeFlight app on the cell issued a warning that supplemental oxygen may be necessary. We were approaching 13,000. We all laughed.
