Ruby Hills

Ruby Hills The Ruby Hills are named for their proximity to the Ruby Sea rather than any rubies to be found in them. They are rich in minerals, though, and at various places have copper, gold (at several locations), iron, assorted semi-precious gems, and such stone as granite, sandstone, limestone, marble, porphyry, and others. The hills run north and south along the coast intermittently for about 375 miles, and also separate the slightly better climate of the seacoast from the extremes of the Eastern Desert.
