a couple of us are planning on heading to the andes for our first real high-altitude expedition next june/july. we are planning on heading down there for 15-16 days with plans to do iliniza norte, cotopaxi, chimborazo, and cayambe. i believe that coming from colorado with extensive climbing above 13,000 feet during the coming winter and spring, climbing only one acclimization peak, iliniza norte, will be necessary before tackling the big three. anyone have an opinion or advice about this? thanks
