D 291 was the first benchmark I noticed on the map when I began researching marks for our trip. Cool, it's at Old Tucson! We don't really have any interest in this old west-style theme park, but it's still neat that there's a benchmark on their property, right next to the parking lot. The mark was an easy find, and a bit harder to photograph since the monument is now beneath a sprawling creosote bush. It is in good condition and the 2001 description is still accurate.
Recovered in good condition near the edge of the parking area for the Old Tucson theme park, as described in the 2001 recovery note. Witness post no longer present. (Also reported that the monument projects 4 inches.)
