Context
Charcoal from a slab-lined hearth constructed of 6 large sandstone slabs, up to 50 cm long. None is shaped. The slabs had apparently been pushed into an old woil surface and some apparently rested against the W bank of the arroyo. No evidence of a construction pit in which the might have been laid.. . Interior meas. was ca. 75 x 50 cm. Fill was ca. 10 cm thick--all charred sagebrush.A linear pile of FCR and oxidized sandstone was found to the N of the hearth, perhaps stockpiled or thrown out after use of the hearth. Pollen: Opuntia, Juniperus and Pinus. Probably used only one time.
