as to the red sandstone, its very common in the uk, because we used to be on and around the equator, at around 50 degrees we were in a desert environment. the action of the sun made the rock much darker red in colour and the green has got to be copper because green marks arent left by any common tree from the tertiary when the climate was that of a desert...the sandstone deposited in the uk has laminations if found on a grand scale.. the fact that the red sandstone has laminations ( deposited in dunes ) means that a tree could not survive in a sand environment alone. its got to be from the element. it wouldnt be discolouring, because in sandstones the only form of discolouring is bleaching, where by the action of water removes the oxide and leaves it white !
the rockies are running along the conservative plate boundary known as the san andreas fault, or the massive tear in the ground between the american plate and the pacific plate.so it is a plate boundary. theyre stil growing because the plates are active
Any idea?? This is probably too easy BUT spec-tack-u-ler

How did these layers of red cliffs form on Mars? No one is sure. The northern ice cap on Mars is nearly divided into two by a huge division named Chasma Boreale. No similar formation occurs on Earth. Pictured above, several dusty layers leading into this deep chasm are visible. Cliff faces, mostly facing left but still partly visible from above, appear dramatically red. The light areas are likely water ice. The above image spans about one kilometer near the north of Mars, and the elevation drop from right to left is over a kilometer. One hypothesis relates the formation of Chasma Boreale to underlying volcanic activity.
What are these stripes from?? (This will be way to easy for JimBob).
Frethack- I'm impressed. Not only did you come up with the right answer, you even found the right glacier. I visited this area several decades ago- I'm sure the glaciers were more extensive then than now. Was intrigued at how the glacier seemed to be more than half medial moraine material.Least you can do now is explain to non-glaciologists what medial moraines are and how they form.

Bristlecone pine trees? 4600 years?
Why should we care???
