This
report contains a map which confirms the approx location of all 4 pillar groups.
Lothagem, Karikole and Jarigole are all as per our coodinates.
Lokoli is also called "Lokori" (as
per the article cited above by Meltwaterfalls) BUT is placed rather closer to the Kerio river than it does -but also it is perhaps too close - hardly "between" the 2 rivers?.
Nb this "
Pillar sites have long been important landmarks to modern Turkana residents, who call them namoratunga (''stone people'').".
It also confirms Lokori as being located at "
nearby hills between the Kerio and Kangatet rivers. Referred to as ''Namoratunga I,''.
I would suggest sticking with the coordinates as per Meltwaterfalls conclusion ...even if it is further away from the river than the article map.
