Barranco de Las Palomeras del Fornocal is located in Sierra and Canyons de Guara Park, in Aragon province of Spain. This is a short but exceptional and deep slot canyon about only 200 meters long. The begining of the slot is located at Las Palomeras bridge on the road Arcusa-Alquezar. On the descent, canyoneers can be admired a deep cave and travertine flow as well as a slot section called estrecho about only 20 inches large (Fat' man Misery section). An amazing work of the erosion for a so quietly brook. The barranco is usually dry with stagnant potholes most of the year.
