Cebrenia Quadrangle - Hecates

Hecates

Recent research leads scientists to believe that Hecates erupted explosively about 350 million years ago which is a not that long ago for Mars. The eruptions created depressions on the flanks of the volcano. And just five million years ago, glacial deposits formed inside these depressions. Some valleys on Hecates show a parallel drainage pattern.

• Hecates Tholus, as seen by Mars Global Surveyor.

• Hecates Tholus topography.

• Hecates Tholus Ridges, as seen by HiRISE. Ridges are to the west-northwest of Hecates Tholus.

• Buvinda Vallis, as seen by THEMIS. Buvinda Vallis is associated with Hecates Tholus; it lies just east of Hecates Tholus.

• Lava channels on flank of Hecates Tholus, as seen by HiRISE under HiWish program. A crater has been partially covered over by lava flows. This crater will be enlarged in the next image.

• Enlarged view of lava filling a crater, as seen by HiRISE under HiWish program.

• Crater on edge of lava flow on Hecates Tholus, as seen by HiRISE under HiWish program. Lava seems to have formed tail shape on the lee side of obstacles like crater rims.
