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. Copyrighted photo by Katia and Maurice Krafft, 1983.
