At the top, a perfectly circular volcanic caldera holds two saline lakes, one larger and greener, one smaller and clearer, and the air is cool enough to grow citrus and stone fruit. This is the highest ground in Sudan, a piece of Mediterranean climate dropped into the middle of the African continent.
