Random Tree Aggregation Radial Fractal Forms cratered terrain southwest of Gusev Crater, Mars Phoenix set fractal Fretted terrain (unit Aft) within Hesperian dissected plains material (unit Hpld). Surface of fretted terrain material is mantled by modern aeolian material which Curl Flame Fractal forms a system of ripplelike, transverse dunes. Gusev Crater-Ma’adim Vallis Region, Mars Rib cage and neck of a Cretaceous plesiosaur (elasmosaur) Basin Floor Assemblage Charmed Meson Basin oor unit 1—Forms rugged surface with small hills of a few hundred meters across. Moderate albedo. Located in the eastern one-third of Gusev crater oor and within de Vaucouleurs west of Gusev. Type area: lat 14.9° S., long 183.7° W. Interpretation: Fluvio-lacustrine sediments formed during wide-spread ponding inside Gusev and de Vaucouleurs by ooding from Ma'adim Vallis and Durius Valles Central peak of moderately degraded impact crater scarp narrow channels Nerve cell narrow ridge Forms cratered terrain southwest of Gusev Crater, Mars Gusev Crater-Ma’adim Vallis Region, Mars Fibonacci spiral Mostly uvial-lacustrine, mass wasting, and aeolian deposits (Gusev Crater-Ma’adim Vallis Region, Mars) Moderately degraded crater (Gusev Crater-Ma’adim Vallis Region, Mars) Sundial Hill Medicine Wheel Fresh crater material (Gusev Crater-Ma’adim Vallis Region, Mars) North Star North Polar Projection star map Fractal edge Möbius Transformation Ursa minor Corona Borealis Fresh crater material (Gusev Crater-Ma’adim Vallis Region, Mars) Draco Gold Beam fusion reaction Organic benzene compound Mandlebrot fractal Herecules Pianola perforations Charmed Meson particle SQRFLD dierential equation Member 1 of Gusev Crater Formation, Mars.
