Summary:

His trip across the Andes and back was his most successful excursion: can clearly demonstate that the western part of the double line of mountains is much older, with fossil shells at 12000ft; the eastern line may be as modern as the Patagonian plains. If proved, this is an important fact in the theory of the formation of the world. Has found petrified trees.
