Nowhere are beds severely disrupted and contorted. Although breccia is abundant in the structure, the breccia does not have the characteristics of that produced by impact. Geologic history of the region does not allow the possibility of that degree of erosion nor does the structure itself show evidence of secondary uplift or deformation, or both. The structure lies on the Chinguetti Plateau and has only a few meters of topographic relief. Strata dip so slightly that field measurement is difficult.
Exposures are poor, and the rocks are extremely weathered.
