| − | <p>Maria are not flat, they drape underlying features, smoothing them out, making detection and interpretation difficult. That is why its fun looking near the terminator when it is near a mare surface. Harry became fascinated with features on, under? above? Mare Nubium west of Bullialdus. He notes a causeway (on Earth an elevated passageway) and wondered what caused it. Rükl noted the causeway in his <em>Atlas of the Moon</em> and a number of observers have commented on it, but what is it? The first thing to note is that the causeway seems to span a broad linear depression that strangely has a designation: Bullialdus W. Lunar Orbiter IV [[iv_125_h2.jpg|shows]] that this trough is bounded on both sides by low mare ridges which define the linear area, but there could be no actual depression. A <em>Consolidated Lunar Atlas</em> [http://www.lpod.org/coppermine/displayimage.php?pid=463&fullsize=1 image] suggests that the south (bottom) side of the trough is actually a broad, flattish mare ridge. By now you may have forgotten about the causeway, which is good, because I have no idea what it is.</p> | + | <p>Maria are not flat, they drape underlying features, smoothing them out, making detection and interpretation difficult.
