Quezon2,
Im not sure if this is footmark, it looks very natural to me...but if its a footmark and right foot anyway,,try locating something like 50 mtrs away backward...that is not a sign of travel but "ON GUARD" as its situated on top of the boulder...
Fernando,
Nice finds, sorry but i dont know their meanings (if there is) the pottery is chinese and its a trademark, perhaps can be considered as antique, keep them..
