There are two other rocks with cup marks at Brae Of Revack :
NJ0364524514 Slightly to the east, Canmore days 5 cups, I think there 6, one very slight mark near the group.
NJ0361924518 To the north westish of the main stone, Canmore says 2, I say three. 1 well preserved cup mark with two that are hard to spot.
I would think there is a lot of rock art in the area, yet to be discovered Not to far away on the north side of the Spey, is Laggan Hill, home to 3 cairns and on its western flank, loads of cup marked rocks.
