- New GPT05 Variant B and Option 3 (Paso El Campanario): Fording Rio Negro is often very challenging and dangerous especially in spring and summer. Based on accounts from locals the route Paso El Campanario was used to move animals until about 2 decades ago. This route crosses Rio Negro higher up in a sediment area where fording should be somewhat easier. The 1000 m ascent to Paso El Campanario looks demanding but not impossible on satellite images.

- It is unclear how tolerant Argentine border police treats hikers that sneak through Argentine territory east of vulcano Planchon-Peteroa. There is a special arrangement between Chile and Argentina that permits the Chilean arrieros of Valle Grande to cross at Paso Vergara by car from Chile to Argentina and drive 15 or 20 km though Argentina before re-entering Chile at an informal border crossing just north of Valle Grande. But I'm unsure if this applies also to "lost hikers". Anyway, in case of an emergency crossing into Argentina from Valle Grande is probably an option. In this case "lost hikers" are probably returned via Paso Vergara to Chile. Also, climbers from Chile and Argentina get from both sides of the border up to the summit of Volcano Planchon and there seams little dispute over this. Trails crossing the border are clearly visible on satellite images.
