during the late 19th century. In a letter in 1889, he proposed building a road through Mount Minuli in order to bypass the old route into Cagayan Valley that was too steep and passed through the highest peaks of the Caraballo mountains located east of his proposed route. He based his proposal on his observations that the five percent inclination of Mount Minuli's slope was suitable not only for carts but also for railways. However, his original plan bypassed what is now the highest point in the pass, which he deemed too steep. Construction of the road began during the American period and was completed in 1928.
