The Earth Day
Earth Day. To commemorate the day, this is a picture from a nice place in the heart of the Maestrazgo highlands: the Source of the Pitarque River. This is not the actual source of the river but is called so because water resurfaces again at this point of the limestone canyon after flowing underground in a section of the headwaters. The canyon was formed by fluvial erosion of Upper Cretaceous limestones. This place that is within the Maestrazgo Geopark (Teruel province, Spain) is visited by many tourists throughout the year.
