The big question now is platinum or carbon for these negs. The Umatilla Rock image has enough contrast for carbon (and maybe too much for platinum), but the grasses and rock neg will need selenium toning for carbon printing to boost the contrast a bit. I would have loved to had been able to used f64 and extended the exposure time out -- that would have increased the contrast due to the reciprocity failure rate of the FP4+. But I was taking advantage of a short period of time of very little wind (there is a little movement in some of the grasses) between day and night. Also the area closes at dusk, I still had to hike back to my van, and I did not know how tight the park rangers were on the time they closed the gates.
Instead of f32 at 2 minutes, I would have used f64 at perhaps 30 minutes (to adjust a little for reciprocity failure and the slow reduction of available light.) As it was, the rocks were exposed correctly but even cooking the neg in the developer I could not get more density in the grasses.
I have one more identical neg of Umatilla Rock to develop -- I'll give it a little less development in case I want to give it a go in platinum.
