Letter from Sanford Rowe and W. W. Bass to Carl Hayden requesting a re-examination on the proposed park boundaries as they are disadvantageous to current land owners surrounding the canyon.

Pima County is blessed with a rich and varying record of human settlement over the 11,000 years representing prehistoric, Spanish Colonial, and Mexican-American influences in our history. The County's archaeological site is the building of structure with traditional cultural values and historic landscapes are all nonrenewable cultural resources.
