Illustrated terrain key

[Zouave]

Hey guys, I'm getting back into PG after a multi-year absence, and am now trying out the scenarios in Legions of Zog.  There is a terrain type on map 91 (hexes 0810, 0910 0911) and I'm not sure if it's a small hill or some rocks.

One of the biggest lacks in PG is, in my opinion, not having a visual guide as to what the terrain types are,  Does such a guide exist?

Thanks for the help.
