Strange structures
About 400 orphic stone structure which archaeologists call " logic gate , " based off of their easy resemblance to " old fashioned field gates , " have been find in Saudi Arabia . Made of low Isidor Feinstein Stone wall that are sometimes built in a rectangular shape the determination and exact escort of the gate are nameless although researchers believe that they date back thousands of years . This picture shows several gates found clustered together . The " logic gate " at bottom right wing is about 1200 feet long . To put this in equivalence an NFL football game field of view is 360 understructure long .
Variety
The William Henry Gates arrive in a act of unlike shapes and sizes . Some of the gates , which archaeologists call " I - type " gates , contain one wall with heaps of rock at the ends of the paries . Two I - case gates , build side by side , can be seen in this mental picture along with other gates .
Groups
Another bunch of gates . The farseeing gate in this picture is about 950 foot . Why the gates cluster together is unsung . The gates be given to be turn up in lavafields that are inhospitable for human sprightliness . However thou of years ago these region would have been wetter and contain more life .
Ancient
Other case of stone structures have also been found in Saudi Arabia . Often these stone social organisation are built on top of or even inside gates . This suggests that the gate are older than the other pit structures . This painting render a logic gate that has a Triangulum I. F. Stone structure with cumulus of stone that lead to a bullseye shaped stone social organisation ( perchance a tomb ) .
Gates
This picture of the lava dome that has gates on it was taken in the 1980s by Vic Camp . The magniloquent lava dome behind it is called " Jabal Abyad " a name which means " white mountain " in Arabic . The lava domes are no longer active although in the past basalt lava poured from them .
In lava
A few gates were found on the slopes of a lava dome . This lava dome , and others in the region , were map by volcanologists Vic Camp and John Roobol in the 1980s . The volcanologists were mapping the " Harret Khaybar " realm of Saudi Arabia where many gates are located .
Older than dirt
Picture of two more Bill Gates take by Vic Camp in the " Harret Khaybar " part in the 1980s . The clay of a lava menstruation can be seen very close to them . The lava flow may be partially covering a third gate . Camp notes that the lava flow tend to cover the gates and other stone anatomical structure something which suggests that the gates are older than the lava flows .
More stones
More stone structures , let in gate , can be seen beside a lava current in this photo . The appointment of these stone social organisation is unknown . Camp suggest that they could go out back around 7,000 eld .
Vents
The " Harret Khaybar " area where many of the gates are locate arrest many volcanic vents .
Urgency
The study of gates has take on some urging as modern day development is threatening or has already destroy some of them . This logic gate still survive in February , 2012 , but was destroy by the goal of 2015 . In addition to the planet view archeologic fieldwork needs to be done to square off exactly how old the gates are and what intention they may have had .
