Boquerón volcano, its summit cut by a steep-walled, 500-m-deep crater, was constructed within a 6-km-wide caldera whose largely obscured rims are visible in this aerial photo from the WSW. The caldera cut an older San Salvador edifice, remnants of which are visible at El Picacho peak (in the shadow behind Boquerón) and El Jabalí (the low peak at the lower left). The buried caldera rim in the foreground is defined by the change in degree of dissection of the volcano's flanks. Guazapa volcano can be seen in the distance at the top of the photo.
