The caves are renown for their karst qualities, namely the numerous fossils from a long-lived reef complex from the Silurian era. Fossils include corals, crinoids, brachiopods, gastropods, pentamerids, colonial tryplasmids and trilobites. Borenore's karst is totally surrounded by igneous rock that flowed from volcanic eruptions at nearby Mount Canobolas.〔 The reserve is situated west of Orange, and is registered as a natural heritage site on the Register of the National Estate for its large diversity of karst morphological and sedimentological features.〔 Camping in the reserve is not permitted. ==Features and location== Access is self-guided and suitable for casual visitors. Entry to the reserve is free. The reserve contains over forty caves, including: * Arch Cave * Tunnel Cavea long, dark passage, about long, which emerges from the base of a large hill. The sink hole is about higher than the entrance at the bottom of the hill. The Tunnel Cave is closed from May to October each year so that a colony of Eastern bent-winged bats, which hibernate there, are left undisturbed. * Verandah Cave 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Borenore Caves」の詳細全文を読む スポンサード リンク
