Abstract: Most of the Paleozoic strata exposed in the Robledo Mountains, Dona Ana County, New Mexico have long been referred to the Hueco Formation divided into four informal members. We re-visit stratigraphy by elevating Hueco to group status in the Robledo Mountains and naming its constituent formations (ascending order) the Shalem Colony, Community Pit, Robledo Mountains, and Apache Da m Formations. The Shalem Colony Formation is about 183 m thick and mostly calcirudites, calcarenites and grainstones. The Community Pit Formation is about 61 m thick and mostly packstones and micrites. The 125-m­ thick Robledo Mountains Formation is packstones, marine shale and red-bed sandstones and siltstones. The Apache Da m Formation is about 122 m thick and mostly alga l plate limestones. Biostratigraphically useful fossils from the Robledo Mountains Formation indicate a late Wolfcampian age.
