Update: Upgraded my gear & going up between June & October
Date is flexible since it is the low season. This will be an unassisted minimalist alpine ascent using only map, compass, & GPS. Ultimately I would like to complete the Polish trail within a week or less, bearing the weather conditions. If not, I will be doing the normal route solo. ETA after checking the trail map, bearing good weather conditions on the normal route from Puente de Inca would be 3-4 days maybe slightly slower, depending on acclimatization & weather conditions.
Here is my itinerary for the normal route:
Day 1
From Destacamento de Guardaparque Horcones (park entrance) 2980m to Confluencia 3350m = 4 hours
From Confluencia 3350m to Piedra Grande o Colorada 3560m =2 hours
From Piedra Grande o Colorada 3560m to Piedra Ibanez 3780m = 6-9 hours
Day 2
From Piedra Ibanez 3780m to Plaza de Mulas 4400m 5-6 hours
From Plaza de Mulas 4400m to Campamento Plaza Canada 5080m = 4 hours up 2 hours down
From Campamento Plaza Canada 5080m to Nino de Condores 5590m = 5 hours up 2 hours down
Day 3
From Nino de Condores 5590m to Camp Berlin 5930m 4 hours up 2 hours down
From Camp Berlin 5930m to the northern summit 6959m 8-11 hours up 5 hours down.
Reverse everything on the way back and will be faster.
My itinerary for the Polish Trail From Punta de Vacas to the northern summit & back by Puente de Inca by normal route
Day 1
From Punta de Vacas 2406m to Refugio Pampa de Leñas 2960m = 6 hours up, 5 down
From Refugio Pampa de Leñas 2960m to Casa de Piedra 3245m = 7 hours
Day 2
From Casa de Piedra to Plaza Argentina Base Camp 4180m = 6 hours
From Plaza Argentina Base Camp 4180m to Portezuelo Aconcagua Ameghino (passing the 1st Polish camp) 5100m = 6 hours
Day 3
From Portezuelo Aconcagua Ameghino 5100m to Polish Camp 2 5830m 6-7 hours
Day 4
From Polish Camp 2 5830m there are 2 Polish routes to the northern summit 6959m One is 10-14 hours the other is 2 days (be ready to bivy up on this one)
If the team members are REALLY skilled, we can also attempt to create our own route.
On the return trip, just reverse the normal route itinerary and it will be faster.
These numbers are just a modest estimate given by the map. You won't be needing much, just 1 1/2-2 week's worth of food (in case of delays by bad weather), light climbing gear, ice screws, snow pickets (optional preferably deadmans) etc., water filter, a burner to melt snow, be an early riser (3-4 am) and be prepared for -45F/-42C at the summit.
