Space Forum / Astronomy / July 2008High Cliffs Surrounding Echus Chasma on Mars
What created this great cliff on Mars? Did giant waterfalls once plummet through its grooves? With a four-kilometer drop, this high cliff surrounding Echus Chasma, near an impressive impact crater, was carved by either water or lava. A leading hypothesis is that Echus Chasma, at 100-kilometers long and 10-kilometers wide, was once one of the largest water sources on Mars. If true, water once held in Echus Chasma likely ran over the Martian surface to carve the impressive Kasei Valles, which extends over 3,000 kilometers to the north. Even if initially carved by water, lava appears to have later flowed in the valley, leaving an extraordinarily smooth floor. Echus Chasma lies north of tremendous Valles Marineris, the largest canyon in the Solar System. The above image was taken by the robotic Mars Express spacecraft currently orbiting Mars. http://antwrp.gsfc.nasa.gov/apod/image/0807/echuschasma_marsexpress_big.jpg > What created this great cliff on Mars?

Mars used to have a much larger moon, or perhaps Mars was once a moon of some other planet. Tidal flexing did the work of keeping Mars warm enough and geologically active along with some degree of water. - Brad Guth Brad_Guth Brad.Guth BradGuth > What created this great cliff on Mars?

The carved channels are identical to those her on Earth, and we all agree as to what caused them. There are also indications that Mars was hit by another body. The impact probably created the crater Hellas Platinia, which is about 4 miles deep and 1250 miles across. It possibly vaporized the water and blew off most of the atmosphere, sending debris into space, some of which may also be responsible for some of the mass extinctions on Earth. And no, Guthball, Mars was not a Moon. No lithobraking there ... Hagar Mars does not fit well with jupiter 4 closest moons. These moons are much more dynamic where as Mars relates well with our moon (cold and Dry) Io is the solar systems greatest volcanic object. Europa has an ice covered surface. The moon Callisto has the most craters. Hagar if all 61 of Jupiters moons are rotating in the same direction I will rule out capture,and have to go with they formed in orbit around Jupiter while the planet itself was growing. These moons tell us a lot. Bert Mars used to be VERY geologically active, BEERTbrain! lmao! Aresically? Oh well. It has the largest known volcano after all.

These moons tell us a lot. Bert Cactus Saul Does this Mars Activity fit with Once upon a time. Think dust and sand storms that have the reality of this spacetime. causing great sarfACE EROSIONS That is reality Bert NASA Knows all about Mars global dust storms. Knows all about those tiny Mars tornadoes. Know how sand and dust can erode Mars surface. All this is reality,but never brought into the picture as carving out Mars surface over billions of years. They can only dream about Mars having great streams,rivers and oceans of running water (once upon a time) They will not face the reality not a molecule was found locked inside Mars rocks,after A BILLION PARTS OF THESE ROCKS tested. Now they claim the Phoenix has found white stuff,and they say if its white its water Who are they trying to kid? Best they call it right and say its frosty CO2. That is reality. Even an 8 year old is to smart to be taken in with NASA con game Bert > What created this great cliff on Mars? Did giant waterfalls once plummet > through its grooves?
