- Comments
- DlOu-9, Laidlaw: Feature 1 consists of two relatively straight lines of stone that converge and terminate on adjacent corners of a roughly rectangular stone enclosure that is believed to have functioned as a pronghorn trap. Feature 2 is a roughly circular stone mass immediately adjacent to the rectangular enclosure, and two nearby stone circles are thought to be functionally related to the other two features. A radiocarbon sample from within Feature 1 produced a date somewhat earlier than expected, but there is no basis for rejecting it.
