You've got your Top Ten, these are my Favorite Five.
Its been a tough choice for me to reduce my favorite pages down to just five. I chose Nitrogen because it demonstrates active cryovolcanism on Pluto. I chose Basins because it taught me something new about Mars and Pluto. I chose Pahoehoe because it clarifies my understanding of a land feature that plagued me for two years. I chose Stirred Not Shaken because it condenses many of the concepts on this entire web site into one page. I chose Eruptions because it connects surface colors to minerals and tidal flex energy levels.
I could have easily gone with Oceans, NH3+H2O, Tilt, Triton, Foundations, All Aboard, Nuts, Core Concepts, Splatter Painting etc...
I'm actually surprised by what I've created on this web site. Sometimes I read my own stuff and ask, "Did I actually come up with that?" This has been a fun learning experience for me.
