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.
