Feature type: symbol Aa14, named
Segment grid: 7C1
Since Boas is so plainly the end of a route, the distance figure XXV placed after the symbol is a puzzle. Miller believes that it is the figure (otherwise missing) for Asopos-Boas. While not rejecting that view, I remain unsure. It would be more typical for the figure to be placed above the relevant name (as on the previous Cytmon stretch), or even below the linework for the stretch.
There are no onward stretches.
