Shammar Mountains


The Shammar Mountains is a mountain range in the northwestern Saudi Arabian province of Ha'il. It includes the Ajā and Salma subranges.

Geology

The Aja Mountains are to an extent made up of granite, whereas the Salma are made up of basalt. The phrase "Hadn formation" was used by Chevremont to refer to volcanic rocks of the area of Ha'il, and was treated by Hadley and Schmidt as being part of a silicic and volcaniclastic sequence referred to as the "Shammar group", in a broader, regional context.

Wildlife

The protected area of Jabal Aja is of ecological significance. Two Asiatic cheetahs, the last known in the country, were killed near Ha'il in 1973, and their skins kept near the Imara Palace for a few days.
