The Berkeley map collection has some Ethiopian maps online which show this tript.
Go to
http://www.lib.berkeley.edu/EART/g8030s200s6.html
and select the bottom left mapsheet.
In the top right (NE corner) of this sheet, is the tript. The zoom function on the map viewing software is a little hard to control though. Note the administrative vs legal Sud-Ken boundary on the index!
