Daedalia Planum
Daedalia Planum is a plain on Mars located south of Arsia Mons at and appears to be relatively featureless plain with multiple lava flows and small craters. It is mostly in the Memnonia quadrangle, but parts are in Tharsis quadrangle and Phoenicis Lacus quadrangle. Modern imagery suggests that it may more accurately be called a "fluctus" rather than a "planum".
There is evidence that an ancient 4500 km-diameter impact basin formed in the Noachian epoch may be centered in Daedalia Planum.
of the Noachian-aged basement on which Alba Mons sits. Also located in the northern rise are lava flows of the Ceraunius Fossae Formation, which are somewhat older than the Amazonian-aged flows that make up much of the central Tharsis region to the south. 
The larger southern portion of Tharsis (pictured right) lies on old cratered highland terrain. Its western boundary is roughly defined by the high lava plains of Daedalia Planum, which slope gently to the southwest into the Memnonia and Terra Sirenum regions. To the east
