Hooper, 1938 Olena Cr., 175 ft., 2 mi. SE Olena, Marin Co., Calif. June 27, Day before yesterday (June 25) left Inverness camp, drove back to main #1 hwy. near P.A. Reyes Station, thence southeast thru Olena to above-mentioned camp on Olena Cr. We are now camped in willow thickets 50 ft. from the stream; Five Brooks is about 1/2 mi. up the creek from where we are. As shown on the P.A. Reyes U.S.G.S. sheet (2d. 1918) alongside Olena Cr. Inverness Ridge is heavily clothed with timber: dense stands of large Douglas fir, madrone, California cay, tan oak; also maple, canyon oak, poison oak, thimbleberry and 1 large redwood. Redwoods become more predominant on Pine gulch Creek (draining into Bolinas Bay). Mr. Boyd Stewart, a Stanford graduate and a most cordial and helpful host, tells us that the above slope about 100 yrs. ago was much more open - this before the redwoods the Douglas firs were at all set - The open meadow-like slopes are now filled in by young Douglas fir, madrone, bay. Redwoods did not come back.
