Do we really know that he is the youngest to climb Mt Whitney? I have previously posted that my friend Rosie Heid (Rosabella) was also 7 when she, her Father and some of her siblings did Mt Whitney way back in 1959.

I do not know if it was a one day ascent or if they came in from the West via Crabtree Meadows, but I think they did a one day from the Portal.
