The quadrangle covers longitudes 270° to 315° west and latitudes 0° to 30° north on Mars. Syrtis Major quadrangle includes Syrtis Major Planum and parts of Terra Sabaea and Isidis Planitia.
Syrtis Major is an old shield volcano with a central depression that is elongated in a north–south direction. It contains the calderas Meroe Patera and Nili Patera. Interesting features in the area include dikes and inverted terrain.
The Beagle 2 lander was about to land near the quadrangle, particularly in the eastern part of Isidis Planitia, in December 2003, when contact with the craft was lost. In January 2015, NASA reported the Beagle 2 had been found on the surface in Isidis Planitia (location is about 11.5265°N 90.4295°E). High-resolution images captured by the Mars Reconnaissance Orbiter identified the lost probe, which appears to be intact.
In November 2018, NASA announced that Jezero crater was chosen as the landing site for the planned Mars 2020 rover mission. Jezero crater is in the Syrtis Major quadrangle at (at 18.855°N 77.519°E)
