Estadilla - La Val

Estadilla is a village at the foot of the Sierra de Carrodilla in the region Somontano de Barbastro. Estadilla is easily reached from the main road between Barbastro and Graus (N123). The site can be accessed from the village but it is probably easier to drop your vehicle near the Puente de los Baños on the road between Estadilla and Estada and then walk the gravel road which starts some steps further northward. Follow the main track down into the valley and you will reach the quarry zone (1) after about 1 km.

(1) Overview of the extraction zone with Estadilla in the back.

I am not sure that the word quarry is the most appropriate word to describe this site. There is no clearly defined pit where stones were cut from the rock. Forgotten stones and traces of (2, 3) of former extractions are scattered throughout the site which is known as La Val.
The main extraction zone (1) lies low in the valley. It is a stony slope with many shallow traces of former activities (2, 3) and several accumulations of stone cuttings (1, 4). Many of the prints do not show the shape of a circle, but have a width of only about a third of a circle (3): I have no idea what that means.

(2) The most outspoken extraction front.

(3) Many prints are about 120° wide.
Throughout the site some mill stones can be found. We located three, but a more persistent seeker might have come up with more.

Two of the stones were found in the lower levels of the site; the third stone was found higher up, almost on top of the ridge (8).

The largest stone (4), with a ∅ of 180cm, has about the same size as the stones found in the quarry of Colungo and may very well have been destined to serve as a crusher stone in an oil mill of the region.

(4) ∅ 180cm, 40cm thick.

(5) ∅ 100cm, 55cm thick.
(6) ∅ 140cm, 40cm thick.

The second stone (5) is made of pudding stone, which wouldn't perform very well in a flour mill, and the measurements are typical for a crusher stone. So this one also was probably meant for an oil mill.

The third stone has a ∅ of 140cm and it is the only piece with the right size to end up in a flour mill (most mills in the region have stones of 130 or 140cm) — at least before composite stones (often from La Ferté) became de rigueur.
