Large lithic blocks in tuff breccias of the Joya de Los Contreras maar form bomb sags that are exposed in three dimensions by differential erosion.  The blocks impacted into the previously deposited lighter-colored tuffs, and the pits were subsequently filled by darker-colored crudely laminated surge deposits.  The Joya de Los Contreras maar,  750 m by 1000 m wide, is the largest of the Santo Domingo volcanic field. Photo by Jim Luhr, 1991 (Smithsonian Institution).
