A plant called opophytum known in Arabic as ghasoul is used heavily in the Samh cuisines of the Northern Borders region. The opophytum is a desert plant that is perhaps only used in the cuisine of the people inhabiting the northern part of Saudi. To make the Bakila, which is a kind of bread, the seeds of the opophytum plant are soaked, ground, then mixed with dates.
About 25 kilometers south of Rafha in the Northern Borders province lies Zubala, one of the most important historical villages in the Arabian Peninsula. Around 300 old wells can be found in the area, some of which are square-shaped and rocky with an area of 100 square meters and depth of 250 meters.
