Acidalia"

Disparate Anomaly:

M00-01674 http://www.msss.com/moc_gallery/ab1_m04/images/M0001674.html Oxia Palus "Transect of flow-ejecta crater" **NOTE** "Tube" is seen in gully along north crater rim.

Description:

Glassy semi-transparent linear feature with a regular convex, cylindrical shape having typical diameters ranging from 140 yards and greater with somewhat regular supporting arch structure. Evident "craters" associated with this linear structure do not have typical impact crater shape and appear to be connected to the linear structure via shallow sup-surface tubes.
