Where is a place that has both Lano Estacado and Buda Limestone geological formations?
Buda Limestone 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.
Hierve el Agua Hierve el Agua (Spanish for "the water boils") is a set of natural rock formations in the Mexican state of Oaxaca that resemble cascades of water. The site is located about 70 km east of Oaxaca city, past Mitla, in the municipality of San Lorenzo Albarradas, with a narrow, winding unpaved road leading to the site. The site consists of two rock shelves or cliffs which rise between fifty and ninety metres from the valley below, from which extend nearly white rock formations which look like waterfalls. These formations are created by fresh water springs, whose water is over-saturated with calcium carbonate and other minerals. As the water scurries over the cliffs, the excess minerals are deposited, much in the same manner that stalactites and iron can also be found and determines the color of a particular stalactite. The calcium carbonate in the water is due to rainwater which passes underground. First it absorbs carbon dioxide, and forms molecules of carbonic acid. This acid comes into contact with underground marble and partially dissolves creating calcium bicarbonate. When the water runs above ground, the excess minerals fall out.
