The original, non-aslsk-style board has the hill as level 2. The ASLSK-style board (and the vasl boards, which used the aslsk-style board as base) *looks* like it is level one. The rules for non-inherent terrain in a hex [B10.1] say that the "terrain (e.g., grain, brush, woods, building) is at the higher level throughout the entire depiction of the terrain in question for LOS purposes (but the actual Crest Line is always used for movement purposes), even if it appears to be rising from the lower level portion of the hill hex. ... For aesthetic purposes, many hexes contain colors representing more than one elevation, but units therein are always considered at the elevation level containing the hex center dot." This means that if you play B10.1 pure, the grain is at the higher level (level 2), and the hex center dot (in the grain) is at level 2 (despite appearing to rise from level one).
This would be fairly conclusive (although the bit about "the actual Crest Line is always used for movement purposes" baffles me), unless you use footnote 3A. Footnote 3A suggests you try to guess where the crest line runs under another terrain type (grain, brush, woods, building). If you are an ardent footnote-three-A-er and are using the ASLSK-style board (or VASL), then the hex is level one. If you follow B10.1 and/or have an old-style board, it is level two.
Note that this applies to all three hexes, F3, G3 and H2. Vasl has done further disservice when it removed the grain by not applying B10.1 to the artwork.
edit: the problems with G3 & H2 on the aslsk-style board (hex center being under grain) do not apply to F3, as there is no grain in F3. As the crest line goes through the hex center dot, it cannot be determined by rule what level the hex is.
