The Pehoe channel complex consists of two conglomerate units, Pehoe A and B (nomenclature of Crane, 2004), separated by a 100 m-thick sequence of thick-bedded sandstones and thinly interbedded mudstone units (Fig.4.1A and B). The Pehoe A member consists of the Pehoe A conglomerate and the Pehoe A thick-bedded sandstone and mudstone. The Pehoe B member is subdivided into the Pehoe B conglomerate and the associated Pehoe B mass transport deposits.

This large format (11 × 17 inch) all color outcrop atlas and field guide was produced for the SEPM Research Conference held in Chile in February, 2009. It contains a wealth of information on the world class deep water outcrops of the Cretaceous of the Magallanes Basin in the Ultima Esperanza District, Chilean Patagonia. This book covers the significant outcrops in the region the Punta Barrosa Formation, CerroToro Fm., and the Tres Pasos Fm.
