Brief Description
The 239,723 ha Purnululu National Park is located in the State of Western Australia. It contains the deeply dissected Bungle Bungle Range composed of Devonian-age quartz sandstone eroded over a period of 20 million years into a series of beehive-shaped towers or cones, whose steeply sloping surfaces are distinctly marked by regular horizontal bands of dark-grey cyanobacterial crust (single-celled photosynthetic organisms). These outstanding examples of cone karst owe their existence and uniqueness to several interacting geological, biological, erosional and climatic phenomena.

Parc national de Purnululu
Le Parc national de Purnululu (239 723 ha), situé dans l’État d’Australie occidentale, contient le massif très découpé des Bungle Bungle, composé de grès quartzique du dévonien érodé pendant 20 millions d’années. Il en reste un ensemble de tourelles et de cônes en forme de ruches aux flancs abrupts, à la surface striée de bandes horizontales de croûte gris foncé de cyanobactéries (organismes photosynthétiques unicellulaires). Ces exemples exceptionnels de karst à cônes de grès doivent leur existence et leur caractère unique à l’interaction de plusieurs phénomènes géologiques, biologiques, climatiques et de l’érosion.
منتزه بورنولولو الوطني
يشمل منتزه بورنولولو الوطني (239723 هكتارا) الواقع في أوستراليا الغربية سلسلة جبال البانغل بانغل المتراصة والشديدة التقطّع. يتميز المنتزه بتكوينه من الكلس الصوّاني الديفوني المتآكل خلال 20 مليون سنة. وقد بقي منه مجموعة بريجات ومخروطيات على شكل خلايا ذات منحدرات قاسية لها سطح مزيّح أفقياً باللون الرمادي الغامق بالسيانو باكتيريا (الطحالب الزرقاء سابقاً) (جسيمات مثيلية ضوئية أحادية خلية). وتعود أمثلة التضاريس الكلسية الاستثنائية هذه التي تشمل المخروطيات الصلصالية في وجودها وطابعها الفردي إلى تفاعل عدد من الظواهر الجيولوجية والبيولوجية والطقسية والتآكلية.

波奴鲁鲁国家公园
占地面积239 723公顷的波奴鲁鲁国家公园位于西澳大利亚州。公园内有挺拔独立的“嘣咯嘣咯山”(Bungle Bungle Range)。泥盆纪时代的石英砂经过2000万年的侵蚀,形成了蜂巢状塔形和圆锥形山峦。这些山峦的峭壁上是规则的暗灰色水平带,由古代藻青菌(一种能进行光合作用的单细胞生物)沉积而成。这些极具特色的圆锥形喀斯特地貌,是由地质变化、生物影响、侵蚀作用和气候变化等诸多因素之间相互影响而形成的。

Национальный парк Пурнулулу
Парк Пурнулулу, площадью 239,7 тыс. га, располагается на севере штата Западная Австралия, в районе сильно расчлененного хребта Бангл-Бангл, образованного песчаником девонского возраста. За последние 20 млн. лет этот песчаниковый массив под воздействием сил эрозии приобрел вид причудливых конических останцев, островных элементов рельефа. На крутых бортах четко видны темные горизонтальные слои – результат жизнедеятельности цианобактерий. Этот ярчайший пример конического карста возник благодаря редкостному сочетанию геологических, биологических и климатических факторов.

Parque Nacional de Purnululu
Este sitio de 239.723 hectáreas está situado en el Estado de Australia Occidental y comprende el macizo de los Bungle Bungle. Este núcleo montañoso de arenisca cuarzosa, sumamente recortado, data del periodo devónico y ha estado sometido a la erosión durante 20 millones de años. El desgaste ha creado un conjunto de torrecillas y conos en forma de colmenas con flancos de pendiente muy pronunciada, cuya superficie está estriada en bandas horizontales por una capa de color gris oscuro formada por cianobacterias (organismos fotosintéticos unicelulares). Este conjunto kárstico excepcional de conos de arenisca es producto de la interacción de diversos fenómenos geológicos, biológicos, climáticos y erosivos.

Justification for Inscription
Criterion (viii): Earth’s history and geological features The claim to outstanding universal geological value is made for the Bungle Bungle Range. The Bungle Bungles are, by far, the most outstanding example of cone karst in sandstones anywhere in the world and owe their existence and uniqueness to several interacting geological, biological, erosional and climatic phenomena. The sandstone karst of PNP is of great scientific importance in demonstrating so clearly the process of cone karst formation on sandstone - a phenomenon recognised by geomorphologists only over the past 25 years and still incompletely understood, despite recently renewed interest and research. The Bungle Bungle Ranges of PNP also display to an exceptional degree evidence of geomorphic processes of dissolution, weathering and erosion in the evolution of landforms under a savannah climatic regime within an ancient, stable sedimentary landscape. IUCN considers that the nominated site meets this criterion.
Criterion (vii): Superlative natural phenomena or natural beauty and aesthetic importance Although PNP has been widely known in Australia only during the past 20 years and it remains relatively inaccessible, it has become recognised internationally for its exceptional natural beauty. The prime scenic attraction is the extraordinary array of banded, beehive-shaped cone towers comprising the Bungle Bungle Range. These have become emblematic of the park and are internationally renowned among Australia’s natural attractions. The dramatically sculptured structures, unrivalled in their scale, extent, grandeur and diversity of forms anywhere in the world, undergo remarkable seasonal variation in appearance, including striking colour transition following rain. The intricate maze of towers is accentuated by sinuous, narrow, sheer-sided gorges lined with majestic Livistona fan palms. These and the soaring cliffs up to 250 m high are cut by seasonal waterfalls and pools, creating the major tourist attractions in the park, with evocative names such as Echidna Chasm, and Frog Hole, Piccaninny and Cathedral Gorges. The diversity of landforms and ecosystems elsewhere in the park are representative of the larger region, and lack a unique aesthetic quality, but provide a sympathetic visual buffer for the massif. The powerful aesthetic experience of the Bungle Bungles has aroused huge interest among the public, and the ranges figure prominently in national and international advertising of Australia’s tourist attractions, matching the prominence of the Uluru-Kata Tjuta National Park. Photographers and travel writers include the Bungle Bungles among the world’s natural wonders, some describing them as Australia’s equivalent of the Grand Canyon.
