Apollinaris Patera is an ancient shield volcano measuring approximately 180 by 280 kilometres at its base and rising to a maximum of 5 kilometres above the surrounding terrain. Shield volcanos are large volcanic structures with gently sloping flanks. The caldera of Apollinaris Patera takes the form of a large crater approximately 80 kilometres in diameter. In this false-colour image, north is to the right. The image also shows the terrain partly covered by thin, diffuse clouds indicated by bluish-tinted areas.
This false-colour image was captured on 26 October 2004 by the High-Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express with a ground resolution of approximately 11.1 metres per pixel.
