The very start of the oasis zone. It is well cultivated, and not a single straw of grass is there without a purpose. Notice the well in the middle of both photos.
In between all the trees of the oasis, run canals. Considering how far you are from the next trace of civilization, how barren the nature is, and how hot it is all through the year, it is surprising to see how strongly the water streams through the canals.
