FIG. 11. (a). Panorama looking south from Cerro Baúl. The Pampa Lagunas pediplain (PL) forms the prominent surface stretching across the llanuras costaneras, whereas the precordillera (on the extreme left and beyond the photo) is dominated by the Altos de Camilaca (AdC) pediplain. A discontinuous, residual bench just below the Pampa Lagunas pediplan represents the Cerro de las Chulpas (DdlC) pediment, which is better preserved in the lower llanuras costaneras. The younger Pampa Sitana (PS) pediment forms dissected ridge spurs below the Pampa Lagunas pediplain, and benches just above the Moquegua valley are remnants of the Cerro Sagollo (CS) pediment. The summits of the Cordillera de la Costa, scarcely visible in the far-right background, are remnants of the Altos de Camilaca (AdC) surface incised by the Pampa Lagunas pediplain. (b). Panorama looking southeast across Quebrada Guaneros (Fig. 6). (Pampa de Congas pediment = PdC; Pampa Guaneros pediment = PG) (c). Panorama looking northwest across the La Llave prospect. (La Caldera surface = LC; Pampa de La Joya = PLJ).
