tbird Posted March 1, 2012 Author Share Posted March 1, 2012 With the moon dominating the sky for the next few days, I really ought to fill the void in my knowledge and learn some of the moon's features. Link to comment Share on other sites More sharing options...

BAZ Posted March 1, 2012 Share Posted March 1, 2012 The straight wall would be some thing to see, it's about 70 mile long and around 600 feet high. Link to comment Share on other sites More sharing options...
Guest Fluke Posted March 1, 2012 Share Posted March 1, 2012 I wonder what caused such a unique feature? Link to comment Share on other sites More sharing options...
BAZ Posted March 1, 2012 Share Posted March 1, 2012 Probably a fault line that got thrust up when there was geological activity on the Moon. There's a few good ones on Earth, but most are under the sea, so are not eroded by weather. Link to comment Share on other sites More sharing options...
Doc Posted March 1, 2012 Share Posted March 1, 2012 It's actually a misnomer it's an actual gradual slope not a wall. Link to comment Share on other sites More sharing options...
Guest Fluke Posted March 1, 2012 Share Posted March 1, 2012 A trick of light then. Thanks for clearing that up Mick Link to comment Share on other sites More sharing options...
Perkil8r Posted March 1, 2012 Share Posted March 1, 2012 Saw that on the last moon cycle. As I recall it was only visible on the one night, the next the light was at the wrong angle to see it. Link to comment Share on other sites More sharing options...
Doc Posted March 1, 2012 Share Posted March 1, 2012 That's right Dan just a trick of the light. Link to comment Share on other sites More sharing options...
philjay Posted March 2, 2012 Share Posted March 2, 2012 (edited) Nice one Paul. Actually Mike it can be seen very clearly over about 4 or 5 nights but after that the sun gets too high and the shadow effect is reduced. One day I shall get to try and spot this when the moon is waning to see what it looks like with the sun from oppossite side, I wonder if it can be seen at all.
