Is there a general term used to identify the high flat features within Noctis Labyrinthus on Mars?

The geological term [mesa](https://en.wikipedia.org/wiki/Mesa) has been used to describe these structures.

> A transitional zone on Mars, known as the fretted terrain, lies between highly cratered highlands and less cratered lowlands. The younger lowland exhibits steep walled mesas and knobs. The mesa and knobs are separated by flat lying lowlands. They are thought to form from ice-facilitated mass wasting processes from ground or atmospheric sources. The mesas and knobs decrease in size with increasing distance from the highland escarpment. The relief of the mesas range from nearly 2 km to 100 m depending on the distance they are from the escarpment.

Mesa is a term used to describe flat topped isolated geological structures that are composed of horizontal layered rocks (usually sedimentary).

If the flat topped structure is not composed of horizontal layered rocks it can be called a plateau or tableland.
