Question: Where is a place that has both Lano Estacado and Buda Limestone geological formations?
Context: Como Bluff is a long ridge extending east-west, located between the towns of Rock River and Medicine Bow, Wyoming.  The ridge is an anticline, formed as a result of compressional geological folding.  Three geological formations, the Sundance, the Morrison, and the Cloverly Formations, containing fossil remains from the Late Jurassic of the Mesozoic Era are exposed.  Nineteenth century paleontologists discovered many well-preserved specimens of dinosaurs, as well as mammals, turtles, crocodilians, and fish from the Morrison Formation.  Because of this, Como Bluff is considered to be one of the major sites for the early discovery of dinosaur remains.  Among the species discovered is the only known specimen of "Coelurus".  Significant discoveries were made in 22 different areas scattered along the entire length of the ridge.  It is included on the National Register of Historic Places as well as the National Natural Landmark list. The Arikok National Park takes up approximately 18 percent of the island of Aruba and includes three primary geological formations: the Aruba lava formation, a quartz diorite formation, and a limestone formation that extends inward from the coast.  These formations have directly influenced Aruba's human settlement, as well as its natural wonders. The High Plains are a subregion of the Great Plains mostly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains.  The High Plains are located in southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico, western Oklahoma, and south of the Texas Panhandle.  The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or from on satellite maps.  From east to west, the High Plains rise in elevation from around 1160 ft to over 7800 ft . Mauch Chunk Ridge (on older USGS Maps) or Mauch Chunk Mountain is a historically important barrier ridgeline north of the Blue Mountain escarpment and 3rd parallel ridgeline south of the Nesquehoning Creek after Nesquehoning Mountain and Pisgah Ridge in the Ridge-and-Valley Appalachians of Northeastern Pennsylvania.  The three lengthy ridges and two valley formations together are literally the first ridges and valleys just south of the Poconos (on the opposite side of the Lehigh River valley)—geological formations which contain some of the richest Anthracite coal bearing sedimentary rocks of Northeastern Pennsylvania.  Historically, the first Anthracite mines in America were located atop Pisgah Mountain at Summit Hill and caravanned by pack mule through the Mauch Chunk Creek valley.  Then the historic Mauch Chunk and Summit Hill Switchback Railroad, the second railway in North America was built along the Pisgah Mountain side of the same valley—and become quite a tourist attraction and is known as the world's first roller coaster, and would inspire others in purpose built amusement parks.  The Mauch Chunk and Summit Hill Switchback Railroad became only a tourist road in the 1890s and thrilled riders until it was liquidated in the 1930s, a casualty of the Great depression. The Semilir eruption was a major volcanic event which took place in Indonesia during the Early Miocene.  This eruption formed Semilir Formation and Nglanngran Formation.  These two geological formations are in Southern Mountains of East Java.  The eruption created two formations consists mostly pyroclastic rock (minor lava flows).  It has incredibly thickness (at least 1200 m).  In contrast, Toba eruption only formed 600 m ignimbrite.  Semilir eruption age date by isotope method is 21 million years ago. The Buda Limestone is a geological formation in the High Plains and Trans-Pecos regions of West Texas whose strata date back to the Late Cretaceous.  Pterosaur remains are among the fossils that have been recovered from the formation. The Woodbine Group is a geological formation in east Texas whose strata date back to the Early to Middle Cenomanian age of the Late Cretaceous.  It is the producing formation of the giant East Texas Oil Field (also known as the "Black Giant") from which over 5.42 billion barrels of oil have been produced.  The Woodbine overlies the Maness Shale, Buda Limestone, or older rocks, and underlies the Eagle Ford Group or Austin Chalk.  In outcrop the Woodbine Group has been subdivided into the Lewisville Sandstone, Dexter Sandstone, and/or Pepper Shale formations.  Thin-bedded sands of the Woodbine and Eagle Ford are collectively referred to as the "Eaglebine" oil and gas play in the southwestern portion of the East Texas region. Brofiscin Quarry, Groes Faen is a disused limestone quarry in Groes-faen, near Llantrisant in South Wales.  It has been designated a Site of Special Scientific Interest due to the exposed Early Carboniferous geological formations on the site.  It was used for about seven years for dumping of toxic waste including PCBs and was capped in 2011. The Hastings Beds is a geological unit that includes interbedded clays, silts, siltstones, sands and sandstones in the High Weald of southeast England.  These strata make up the component geological formations of the Ashdown Formation, the Wadhurst Clay Formation and the Tunbridge Wells Sand Formation.  The term 'Hastings Beds' has been superseded and the component formations are included in the Wealden Group. Aizkorri or Aitzgorri (] , meaning in Basque 'bare stone', literally 'red stone') is a massif, the highest one of the Basque Autonomous Community (Spain) with 1,551 m AMSL at its highest point (peak Aitxuri, meaning 'white stone').  The massif is formed by a crest of limestone summits aligned north-west to south-east all in a row at the south of the province of Gipuzkoa, namely Artzanburu, Andreaitz, Arbelaitz (1,513 m), Iraule (1,511 m), Aitxuri, Aketegi (1,549 m) and Aizkorri (1,528 m).  Despite its slightly lower height, this summit is the most popular one.  The Aizkorri massif is one of the most conspicuous geological formations on the Basque Mountains range.
