I don't know about the name. No one we asked knew. A sub peak is called Muertito = Little death.
Jag har inga fler bilder. Janne har senare.

Thanks for reminding me. That's the map we used. I forgot to add that info.
It would be nice to give an idea of the scale of this climb. You don't mention how far it is or even how many days to expect. For a person casually looking for a mountain this would be nice to know.
