NAC Anaglyph: Alphonsus Vent

A dike (subsurface magma body) was likely intruded under the floor of Alphonsus crater creating an array of fractures seen here. Image is 5700 meters wide, north is towards the top [NASA/GSFC/Arizona State University].

The distinctive factures provided pathways for explosive lava eruptions resulting in haloes of dark ash. These deposits are known as dark halo craters, or DHCs. Anaglyph of one of the Alphonsus DHCs, located at 13.518°S, 358.528°E. NAC images M1098866596L/R, M1098859450L/R. [NASA/GSFC/Arizona State University].
