[10] The atmospheric pressure at the summit of Ascraeus Mons averages 100 pascal (1.0 mbar);[11] this is only 17% of the average surface pressure of 600 pascal. The dust forms a mantle over the surface that obscures or mutes much of the fine-scale topography and geology of the region. Ascraeus Lacus had been named after Ascra, the rural birthplace of Hesiod; in Greek, the word “Ascraeus” is a poetic metonym for “rural.” The surrounding calderas have ages of about 200, 400, and 800 Myr old, or earlier.
