Lower Table Rock, 7 miles N. and 3 miles W. of Medford, Jackson Co., Oregon. Elevation 1300 ft.
July 26 Broad from N -> S as from E -> W. Am guessing that the hill (cont) is about one mile in greatest dimension. At least on the E. and S. sides, a basaltic rimrock borders the flat summit. A similar mesa is about 3-4 miles away to the NE, except little woodland is visible on its slopes. The rimrock is about 80 ft in vertical extent, with slopes gradually changing from 45° to 30° as one descends the slopes toward the plain.
Much of the east slope is covered with nice white oak forest with scattered ponderosa pines. Oregon ash and madrone grow to good size in only limited places, mostly on the SE slope. As previously noted, some fair size Douglas firs grow near the rimrock on the east side, but not on the south or southwest sides (other sides not examined). On the south side of the "Rock," the trees were smaller and more widely spaced. On the east side were large patches of brush and grasses, dominated by manzanita and Ceartotus and patches of star thistle and some thistles. On the south slope, there was lots more brush, esp. Ceantotus, and thistles. The Rogue River flows east to west by the south side of Lower Table Rock, the river banks mostly denuded of riparian trees. A small creek flows into the river against the SW-most flank of Lower Table Rock (creek unnamed on my maps. There is no active flow currently, but the mouth of the creek is a broad bay in the river channel. In the upper part of this "bay" are lots of duckweed. The thickest and largest contiguous woodland grows upslope from this small
