The Cairn Hills

  This barren string of hills is the northern prominence of the massif known as Abbor-Alz.  It's name refers to the ancient discovery of mysterious burial sites here, containing relics from an unknown civilization.  These relics proved to be of great value, though their acquisition was a matter of no little risk.  Though Greyhawk was no more than a wild trading town at that time, this was the beginning of its role as a starting and ending place for would-be adventurers and treasure seekers.
  The hills fringe the territories of the Free City on two sides, providing strong and visible borders.  In addition, their rugged nature and general lack of settlements make them the wildest territory near the City of Greyhawk.
  The hills are the remnants of an ancient range of mountains.  Their foundation is the bedrock of the earth itself and in places this rock - dark gray granite and rose quartz - juts through the shallow covering of earth that gives the hills their characteristically drab appearance.
  It is the same bedrock that guards the gems from which the Cairn Hills derive their most significant commercial usage.  The Free City of Greyhawk operates several vast mining regions in the hills, producing a variety of large, high-quality gems, especially emeralds and rubies, though a few diamonds are unearthed here as well.
  Most of the diamonds lie among the hills to the north of the Selintan River, land claimed and jealously guarded by gnomes.  The humans have found it easier and much more practical to purchase diamonds from gnomish miners rather than try to conquer these hills.  Though the surface of the land might fall to human invasion, the underearth - where the gems are - would remain forever in the hands of the industrious gnomes.
  The northern slopes of the hills, in their gentle descent to the shores of the Nyr Dyv, offer little in the way of mineral wealth or any other commercial enterprise.  This might be why the halflings have been allowed to live here unmolested for so long.
