A thick stack of about 20 lava flows is exposed in the 230-m-high eastern walls of Santiago crater, overlain by a sequence of black basaltic ash deposits. The 600-m-wide Santiago crater is seen here from a viewpoint on the SW crater rim. Santiago crater is located on the west side of the post-caldera cone of Nindirí, and has been the source of most historical eruptions of Masaya.
