Mesa. A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain. They have been a popular subject for artists throughout history. Their imposing presence and unique geological formations have inspired works across various mediums and cultural contexts. Mesas often represent strength, resilience, and the enduring nature of the land. They can also evoke feelings of solitude, contemplation, and a connection to the natural world. Additionally, mesas often hold cultural significance for indigenous peoples, associated with sacred sites, ancestral stories, or spiritual beliefs. Artists can use mesas to convey the rich cultural heritage of a region and create dramatic landscapes that capture the stark contrast between the flat top and steep sides. Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock, e.g. shales overlain by sandstones. The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike plateau, whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term mesa applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as tablelands. As noted by geologist Kirk Bryan in 1922, mesas .stand distinctly above the surrounding country, as a table stands above the floor upon which it rests. It is from this appearance that the term mesa was adopted from the Spanish word mesa, meaning table. A mesa is similar to, but has a more extensive summit area than a butte. There is no agreed size limit that separates mesas from either buttes or plateaus. For example, the flat-topped mountains which are known as mesas in the Cockburn Range of North Western Australia have areas as large as 350 km 2. In contrast, flat topped hills with areas as small as 0.1 km 2 in the Elbe Sandstone Mountains, Germany, are described as mesas. Less strictly, a very broad, flat-topped, usually isolated hill or mountain of moderate height bounded on at least one side by a steep cliff or slope and representing an erosion remnant also have been called mesas. In the English-language geomorphic and geologic literature, other terms for mesa have also been used.
