The EMERI-II Expedition: April 2006 The 29 April 2006 we moved from Bu Hlega in Karkur Ibrahim in search of the cairn built at the 22N-25 N confluence by Captain Oreste Marchesi during the "Missione Geotopografica al Gebel Auenàt" in 1933. We found the cairn 1.6 km NNW from the true 22N-25E confluence point recently visited by Dave Morrison and party.
The 1933 topographic mission used expedite methods to locate the confluence so no wonder it is not a very accurate determination as it is possible today with WAAS enabled GPS (about 3 meters with non professional grade GPS units!)

Anyway it is important to remember that this confluence became an effective international tri-point boundary only on July 20-1934, after the Rome Agreement between the British and Italian governments; at the time Libya was an Italian colony and the western sector of Jebel Uweinat (Gebel Auenàt in the Italian maps and scientific papers) was under the Italian flag.

The actual point of the 22N 25E confluence is 150 meters above the plane, on the slope of the gully, at the picture centre. Behind the gully the slopes of the northern Jebel Uweinat ridge.
