Friday Field Foto #120: Roadcut of fine-grained strata in Patagonia
This week’s Friday Field Foto is from the Upper Cretaceous Magallanes Basin strata in southern Chile. The “natural” outcrops in this region are exceptional, but a geologist will always take advantage of roadcuts when they can. The national park in this region is attracting more visitors with each passing year, which has resulted in some road improvements and construction. The photo below is an essentially brand new roadcut exposing the fine-grained deep-marine sedimentary rocks of the Punta Barrosa Formation.
