Territorial memory · the thread of water
The rivers that make the Alto Tajo
A river basin gathers lands that share water. Following it leads from mountain springs to villages, salt pans, watermills, and timber-driving routes.
Start at the headwaters of the Sierra de Albarracín, follow the Gallo to Molina or enter via a nearby stream. Every watercourse has an outlet and a living memory to follow.
From tributaries to the river
All this water reaches the Tagus
The branches beneath each name are the streams that feed it. You can open any and follow its path downstream.
Arandilla and Bullones join via the Gallo. The Sarguilla joins via the Hoz Seca. The Salado or Linares joins via the Ablanquejo, and Cuervo and Escabas via the Guadiela.
Diagram of hydrological connections, without geographic scale or sequence of confluences. Brings together 17 documented watercourses; minor springs and brooks are detailed within each basin.
The Guadiela branch and the Ompolveda extend the reading downstream from the Alto Tajo. Their junctions with the Tagus are at Bolarque and Entrepeñas.
Enter by a river
Alto Tajo and headwaters
Tajo
Rising at over 1,800 metres in the Montes Universales, still known as the Tajillo at Las Juntas, carving down through the timbermen's canyon as far as Valtablado.

Gallo
From El Tremedal to Molina and through the Barranco de la Hoz: the Gallo cuts through Triassic red sandstone and joins the Tagus at the San Pedro bridge.
Alto Tajo and headwaters
Hoz Seca · río del Puerto
Rising as the Río del Puerto in the Sierra de Albarracín, disappearing into sinkholes and through Cueva del Tornero, joining the Tagus at Las Juntas.
Alto Tajo and headwaters
Cabrillas
Descending from Checa to Taravilla between red sandstone towers and gorges populated by raptors; at its source, the Arroyo de Checa forms the Aguaspeña tufa.
Alto Tajo and headwaters
Arandilla
Descending from the Sierra de Aragoncillo, carving a red rodeno canyon in Cobeta past the Montesinos hermitage, joining the Gallo.
Alto Tajo and headwaters
Bullones
Descending from the Montes de Picaza to the Gallo past the historic salt works of Terzaga and Armallá: the salt river of the Señorío.
Alto Tajo and headwaters
Ablanquejo
From the pine woods of Ciruelos to the Hoz del Ablanquejo: juniper chozones, sandstone valleys, and a rugged trail-less canyon.
Alto Tajo and headwaters
Linares · Salado
From Cueva de la Hoz to the Ablanquejo: the Linares or Salado carves the Valle de los Milagros and passes Casares cave and the salt pans of Saelices.
Alto Tajo and headwaters
Tajuelo de Poveda
A compact valley shaped by open-cast mining: in the Tajuelo and Merdero catchments between Poveda and Peñalén, kaolin has been mined since 1965.
Alto Tajo and headwaters
Huecos · rambla Malila
Rising at the foot of Mojón Blanco on the Teruel border and narrowing into Rambla Malilla, a powerful rocky defile meeting the young Tagus.
Alto Tajo and headwaters
Sarguilla · rambla de las Sarguillas
A seasonal limestone canyon devoid of riparian woodland, designated a River Nature Reserve; it feeds the Hoz Seca near Checa.

Alto Tajo and headwaters
Arroyo de Checa
Rising right beside Checa, creating the living travertine tufa of Aguaspeña and joining the Cabrillas: the ancient Genitores or Gil de Torres stream.
Alto Tajo and headwaters
Arroyo de la Vega de Saelices
The Arroyo de la Vega de Saelices brings water to the historic salt village: the San Juan salt pans, documented since 1203.

Basin continuity
Guadiela
Rising near Cueva del Hierro, flowing some 115 km through the Serranía de Cuenca and carving the Hoz de Beteta before joining the Tagus at Bolarque.
Basin continuity
Cuervo
Emerging from a travertine tufa spring beside Vega del Codorno, designated a Natural Monument since 1991, draining into the Guadiela.
Basin continuity
Escabas
Rising at 1,500 metres near the sources of the Cuervo and Júcar, flowing 60 km across the Serranía de Cuenca to the Guadiela.
Basin continuity
Ompolveda
Descending from the Peralveche plateau in a gentle valley to the Entrepeñas reservoir on the Tagus.
