Description: Length 2.4km, depth 110m. See OUCC Proc. 7 » for detailed description. Upsteam is Samoreli with impressive large chamber; water incoming from upstream sump. The stream exits and crosses Pozo del Molino – a deep open pit with remains of a mill. Downstream of that the large passage becomes a tight squeeze and duck (often blocked) leading to 12m pitch and a fine series of cascades and flowstone pools of the main stream passage. This joins the mainly dry passages coming down from Cueva de la Fuentica big entrance. The streamway continues alongside the Main Chamber series to a sump which is about 30m from the resurgence (Manantial de la Aldea).
