This scoria cone on the floor of the Boquerón summit crater at San Salvador was built during an eruption that began on 6 June 1917 on the upper north flank of Boquerón. A chain of scoria cones formed, and a lava flow traveled to the northwest, cutting the railroad between Quezaltepeque and Sitio del Niño. The Boquerón summit crater lake began to boil by 10 June and disappeared by 28 June, after which this small cone (Boqueroncito) formed on the crater floor.
