Cerro Quemado cinder cone near of the outlet of Lake Güija has been extensively quarried, and only a remnant of the cone remains. The San Diego volcanic field straddles the El Salvador/Guatemala border and contains numerous basaltic cinder cones and associated lava flows on both sides of Lake Güija.

An extensive volcanic field of fresh basaltic cinder cones and barren lava flows near Lake Güija is named after its largest feature, 781-m-high Volcán de San Diego (upper right). A large basaltic lava flow from the San Diego cinder cone dammed the drainage and was responsible for the formation of 12-km-long Lake Güija, which lies mostly in El Salvador, but extends across the border into Guatemala. Cerro el Tule cinder cone in the center of the photo lies near the eastern shore of the lake, due south of Volcán San Diego.

Volcán de San Diego (upper right) is seen here from the south at the outlet of Lake Güija. The lake was formed when lava flows from San Diego blocked the channel of the Dasague river. Cerro el Tule (left) lies across a narrow channel from the lower flanks of San Diego and during higher water levels forms an island. The 468-m-high Cerro el Tule contains a well-preserved summit crater and is one of the many morphologically youthful cones of the San Diego volcanic field.

A panoramic view from the NE shows from left to right Volcán de San Diego, Cerro Masatepeque, and the two peaks of Loma Iguana and Cerro las Iguanas. Laguna de Metapán is at the right. San Diego is the largest cone of a volcanic field surrounding Lake Güija near the El Salvador/Guatemala border. Basaltic flows from smaller vents of the San Diego volcanic field were responsible for blocking drainages and forming Laguna de Metapán. The larger Lago de Güija was formed as a result of flows from Volcán de San Diego itself.
