In ancient times, Petra might have been approached from the south on a track leading across the plain of Petra, around Jabal Haroun ("Aaron's Mountain"), the location of the Tomb of Aaron, said to be the burial place of Aaron, brother of Moses. Another approach was possibly from the high plateau to the north. Today, most modern visitors approach the site from the east. The impressive eastern entrance leads steeply down through a dark, narrow gorge, in places only wide, called the Siq ("shaft"), a natural geological feature formed from a deep split in the sandstone rocks and serving as a waterway flowing into Wadi Musa.
