Morphology Notes  ?   Supplementary collections: Photo, soil (rock). Here the Bakers Cypress was the dominant forest cover. With some Sugar Pine, Jeffrey Pine, and in places considerable Knobcone Pine. To the west and above the Cypress trees will be found a few Western White Pine trees as well as a very few Sadler Oaks. That is along the main trail. What one will find on the ridge far above where this specimen came from I have no idea. Southwest exposure. Growing right in the rock. Extent: the Seiad Grove must cover about a square mile section- over a mile in either direction. The District Ranger at Seiad Valley told me that the Seiad Grove must cover about a section. Remarks: can furnish photograph of whole tree and panoramic view of Seiad Grove. This was the largest Cypress tree that I found in the Seiad Grove. DBH of same 24.8281 inches. Estimated height with lightning killed top at 75 ft. Rock samples collected from near base of same are being sent to the Arnold Arboretum, Stanford University, and Dr. Wolf. These were identified by Prof. Staples of the University of Oregon 12/8/39. Periodite, an igneus rock - basis of serpentine - and in this case rich in chromium ore. Foot Note B: One of the miners working (opening a new prospect) on the opposite (east) side of the sharp ridge from whence came said herbarium material (west side), told me that the elevation of their work was around 4700 feet. I figured said tree to be about at the same level or maybe a hundred feet or so higher [etc]. You will notice on the south side of the West fork of Seiad Creek some little distance below the cook house a small Bakers Cypress tree. The elevation here might be say 2100 feet; so you see the Seiad Grove covers quite a wide range as to elevation. I took my pictures as I went up the mountain, eating my lunch near the largest tree I found at the Seiad Grove, then on my way back down to camp I collected my herbarium material. Picture #3-447 58 10 Base of largest Bakers Cypress found in Seiad Grove. This picture is looking north; scar not showing. Herbarium material #30 came from this tree. Picture #3-444 55 7 Base of largest Bakers Cypress found in Seiad Grove. This picture taken looking south. Lightning scar showing.
