The guide of the 7 Summits Club Artem Rostovtsev reports from Mexico:
A group called "Not named yet" after a short initial acclimatization in Mexico City (2250m.n.u.m.), we moved further towards our goal - the highest volcano in North America, Mount Orizaba. On the way today we walked between the Aztec pyramids in Teotihuacan. We will spend the night next to the volcano La Malinche (4450m), where we have to climb tomorrow – so we will continue our acclimatization.
