film01 - film18: Division of State Parks, Crenshaw, "#902"
film19 - film61 : Division of Parks, Crenshaw, 7/15/82  

Notes by KK 10/6/08 (7/15/82 dates Unlikely original photo dates, since shows helicopter visits to sites in spring, most likely between Little Su River (film 19 shows roadhouse, at Little Su?  unknown for sure) and Joe Redingtons place at Flathorn Lake (unconfirmed, but suggested by Jon Brautigan, 10/3/08)

Crossing pix (38 and higher) may be of the trail crossing at Fish Creek, but could also be Little Su. Needs further investigation.
