South of Chavez Siding Rd. on the east side of the Santa Cruz River. Possible new de Anza trail, connecting Tubac to Elephant Head..
Have walked to both trailheads from here along the R/R tracks, South to Tubac and north to E.H. The cache is to the west of the trails along the tracks because of the R/R ROW restriction.
Congratulations to RS Arizona on the FTF
