On a hilltop south of town, Pascual Abaj (Sacrifice Stone) is a shrine to the Maya earth god Huyup Tak'ah (Mountain Plain). A stone-faced idol stands amid a circle of squat stone crosses in a clearing. Said to be hundreds – perhaps thousands – of years old, it has suffered numerous indignities at the hands of outsiders, but local people still revere it.
Chuchkajaues come regularly to offer incense, food, cigarettes, flowers, liquor and perhaps even a sacrificial chicken, in thanks and hope for the earth's continuing fertility. The area is littered with past offerings. The worshippers won't mind if you watch the goings on, but be sure to request permission before taking any photos. You may be asked if you want to make an offering yourself.
Even if there are no ceremonies going on, you can still see the idol and enjoy the walk up the pine-clad hill. To get there from the plaza, walk down 5a Av, turn right into 9a Calle and proceed downhill. At the bottom, bear left along a path and head up through either of the morerías (ceremonial mask workshops) that are signposted here; the one on the right houses a museum of local culture. Exiting at the rear, follow the path uphill through the trees to the top of the hill.
