227 In the less exposed areas there are live oaks and Pinus saliniana - but only inside canyons. Further on down the road the vegetation changes to an open and wood- land of deciduous oaks, live oaks, P.saliniana with some brush. Panderosa is only in the protected mesic spots. 207.5 South fork of the American River gaining up a canyon - the west slope is a dense transition forest - typical. On the opposite - west facing slope the vegetation is predominately a stunted woodland of globular live oaks, saliniana, a few panderosa - in contrast to litchocedrus & clanglas fir on this side. Exposure plays an important role in this rugged terrain! The "upper Sonoran" species are on the arid exposed sites & the transition in the more mesic ones, also the underlying rock may be important. Going up this canyon the ridge to the east has [illegible] more extensive patches of marganita on the top - this is a Shierling pattern. 210.2 Placerville bought film & gun-dawn x50 213.2 Turned off to Rescue - down a hill, brush woodland and panderosa forest, orchards & grassy pastures.
