that second supposed oasis is actually an archeological site
called hassi el mislane
& the spec for the arc is a 1km radius
as compared with that of the dzlytn arcs 6plus mile radius
& the depa arcs 12 mile radius

but a third african curve has indeed just been found
& right next door to these first 2
on the lyne line
& it probably has the longest radius & longest arc of all
but it is either indefinite or of unknown delineation
