·    No glyphs given in K&H.

·    Features:

o Boulder in the shape of a series of steps, climbing from left to right.

o Inside, darkness (=cross-hatching) – common but optional.

o Skull in bottom right corner.

·    Note that while most examples have steps ascending from left to right (i.e. asymmetric), TOK.p17.r4.c4 has a symmetric variant where the “wood” element divides the interior into two sections, and only the right section is cross-hatched.

·    Do not confuse this with the visually similar CH’EEN. Although some variants of MUK are divided by a vertical line or band, with darkness in the right half, MUK has a “step” outline on the left and top, while CH’EEN has a boulder outline. Also, MUK has an infixed skull, whereas CH’EEN has one of the three elements bone-jaw, eyeball or K’IN.

·    It is unclear to me why the -nal is read by some sources, even when there isn’t a NAL present. Wouldn’t it be more sensible to have muk = “to bury” (one logogram MUK) and muknal = “grave” (two logograms MUK-NAL)?
