Brief report:
Started walking at 7:30am from an elevation of 3160 meters (10,367 ft)....not too far from Hosteria La Estacion. Summited at 12:40pm. Stayed 10 minutes at the summit taking the cloudy, summit photo and eating a snack. A thunderstorm developed around 2:00pm while descending. Back to where we started at 3:15pm (~ 7 hrs 45 min roundtrip). Then, onto Hosteria La Estacion for a hot shower and a delicious dinner.
