Sasco was once a community of about 600, which featured a smelter, associated company buildings, residences, saloons, stores, and the Hotel Rockland.
A post office served the community from 1907 until 1919. Today remnants of Sasco are scattered over a wide area.
SASCO stands for "Southern Arizona Smelting Company".
A minor dirt road heading south about 0.1 of a mile cast of a large power line leads to a concrete powder house, foundations of two adobe buildings, and a waterless stone fountain.
East of that turnoff, a road to the north off the main road goes to the ruins of the smelter. An exploration on foot leads to the old smelter stack base (Inscribed "Sasco, '07" ), the smelter foundations, a series of concrete monoliths, an enormous slag pile, and a railroad platform with the name of the town etched to concrete.
East of the main site stands a structure that says "City Hall" hut that actually was a jail. Beyond it stand the volcanic stone walls of the Hotel Rockland, vandalized, spray painted, and forlorn.
A short drive east to La Osa Ranch Road, then north .6 of a mile to a "Y" in the road, leads to the Sasco Cemetery. Among the memorials are several concrete crosses, reminders of the devastating influenza epidemic of 1918 – 1919 that claimed more than a half-million American victims.
