Ancient caldera in Apollinaris Patera   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.  This map shows the location of Apollinaris Patera, a volcano lying at approximately 7.2° South and 174.6° East. It is an ancient shield volcano located at the northern edge of the Southern Highlands, lying to the south-east of Elysium Planitia and to the north of Gusev Crater. The volcano measures approximately 180 by 280 kilometres at its base and rises to a maximum of 5 kilometres above the surrounding terrain.  The caldera of Apollinaris Patera, an ancient, 5-kilometre-high volcano northwest of Gusev Crater. In this true-colour image, the terrain is partly covered by thin, diffuse, whitish-appearing clouds. North is to the right.  This black and white 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.  This 3D anaglyph is based on data 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. Accompanying colour scenes were derived from the three HRSC colour channels and the nadir channel, while this anaglyph image was calculated from the nadir and one stereo channel.
