The bottom of El Jagüey maar is occupied by a small lake which marks the level of the groundwater table that lies about 60 m below the top of the surrounding lava plain and serves as a critical regional water hole for cattle (foreground). Explosions occurred when rising magma encountered this aquifer and produced the intersecting La Breña-El Jagüey maars. The NW rim of the 1,400-m-wide La Breña maar forms the horizon beyond the saddle between La Breña and the 700-m-wide El Jagüey maar.
