A network of channels known as Elivagar Flumina flow away from the crest of the crater into a catchment basin.[4] The feature is named after the goddess of wisdom in Etruscan mythology, Menrva.[1] References1. ^1 2 {{cite web|title=Menrva|url=http://planetarynames.wr.usgs.gov/Feature/7025|website=Gazetter of Planetary Nomenclature|publisher=USGS, NASA, IAU|accessdate=January 17, 2016}} {{Titan}}2. ^{{cite journal|last1=Wood|first1=Charles A.|title=Impact craters on Titan|journal=Icarus|date=August 28, 2009|volume=206|doi=10.1016/j.icarus.2009.08.021 |url=http://www2.ess.ucla.edu/~jewitt/class/Surfaces_Papers/Wood_10.pdf|accessdate=January 17, 2016|bibcode=2010Icar..206..334W}} 3. ^{{cite book|last1=Bond|first1=Peter|title=Exploring the Solar System|date=March 12, 2012|publisher=John Wiley and Sons|isbn=978-1-4051-3499-6|url=https://books.google.ca/books?id=UIYcAqdH27wC&dq=menrva+crater&source=gbs_navlinks_s|accessdate=January 16, 2016}} 4. ^{{cite web|last1=Gilliam|first1=A.E.|last2=Jurdy|first2=D.M.|title=TITAN’S IMPACT CRATERS AND ASSOCIATED FLUVIAL FEATURES: EVIDENCE FOR A SUBSURFACE OCEAN?|url=http://www.hou.usra.edu/meetings/lpsc2014/pdf/2435.pdf|publisher=Department of Earth and Planetary Sciences, Northwestern University|accessdate=January 16, 2016}} 2 : Impact craters on Saturn's moons|Surface features of Titan (moon) |
