The Wadi el-Hudi is important in archaeology for its high number of rock inscriptions and stelae, mainly dating to the Middle Kingdom, as amethyst was especially popular in this period. The Wadi el-Hudi ends in the Nile valley a few kilometers north of Aswan and is coming there from the South-East. The ancient amethyst quarries are about 20 kilometres south-east from Aswan.[1]
