Patelka 1943 June 15 - Ioni E Hayfork, 2400 ft, Trinity Co., Calif. We left our Begum camp in mid-afternoon and resumed travel westward along Calif. Highway 36. We passed through Platin and Wildwood. A short distance beyond Wildwood, we found we had to take a side road connecting 36 with the Hayfork - U.S. 299 connection . (The Wildwood- pasted as Peanut road was not passable because of high water.) We continued along the side road, which follows a tributary of Hayfork Creek, and arrived in the Hayfork Basin about 6 p.m. In the vicinity of Platin (Shasta Co.), we began to observe Black oaks more frequently, and not far beyond, yellow pines. Beyond the ridge separating the Sacramento Valley drainage from that of the Pacific Coast (Shasta Co.- Trinity Co. line), coniferous forest became the predominant vegetation type (although it was glauce noted east of that ridge as we came up from the lower woodland level). The species prominent in the forest along the from the main ridge road leading to Wildwood were Pini ponderosa Quercus kelloggii, and Quercus garryana, and Pinus strobus toxifolia. Also, Libocedrus decurrens and Arbutus menziesii were noted. The Hayfork Basin is intertendend by a forest of primarily yellow pine, and oak,
