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