Hi Corax and everyody!
According to some friends of mine (Mountain guides in Mendoza)the Vallecitos peak has two summits: "False" Vallecitos 5470m, wich is the most climbed (the one with the iron stick...or what remains of a metal cross???).
True Vallecitos (aprox. 20 higher) is the futher north promotory that one can see from the "false", but best known top summit
The latter is dangerous, loose rock and reached few times.
The first one, usually climbed is considered technically the summit.....it's the same discussion of the two Ojos del Salado summit...doesnt matter both are te target.;-)
