It is located 225 Km on the West Side of Puerto Deseado. 130 million years ago, this place was an orchard destroyed by volcanic action. Vast forests of araucaria (kind of pine) and other species perished and were covered by volcanic ash. Having the exogenous elements disappeared by effect of the wind and water; today it resembles a ghostly landscape of petrified tree trunks, some of them 35 meters high and with a diameter of 3 meters.

Further north, nearby Sarmiento (Chubut) you can find José Ormaechea Petrified Forest.

It is the scenery of imposing glaciers descending from the continental ice field. Thirteen glaciers on the Atlantic side break into huge ice towers onto the waters of the lakes Viedma and Argentino. The front faces of the glaciers Perito Moreno, Mayo, Spegazzini and Upsala fall upon the latter, at a short distance from the shores of the glaciers Agassiz, Onelli, Ameghino and Frías. Tertiary granite elevations covered with thick Andean forests are part of this spectacle. You can go sailing across the lakes to appreciate more closely the front face of the glaciers. Go trekking and climbing to the millenary ices. El Calafate is the closest service center, which can be reached by air or bus from Río Gallegos.
