Shammar Mountains

The Shammar Mountains (جِبَال شَمَّر) is a mountain range in the northwestern Saudi Arabian province of Ha'il. It includes the Ajā (أَجَا) 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 (1982) to refer to volcanic rocks of the area of Ha'il, and was treated by Hadley and Schmidt (1980) 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.
