The first written reference to "Picu Urriellu" as "Naranjo de Bulnes" is credited to the German geologist and engineer, Wilhelm Schulz, who, in 1855, published the first topographic and geological map of Asturias.
In 1854 he moved to Madrid, where he taught in the Mining Engineering School and was vice-president of the Geological Institute.
