Post-live wiki review for class by Erin: 

 The article is well-cited, but can take a bit of a conversational tone at times: "in general", "as previously mentioned", etc. These can be cleaned up to speak with more authority about your subject and make the article flow smoothly without sounding informal. The figures are well done, (and this is a nit-pick, but might be difficult for color-blind persons to see, with all the green?) There does seem to be some confusion (as Michael pointed out) about orientation of some features, just add some descriptors like north, south, southwest, etc.
