ACCESSING JEWELL TRAIL. On two occasions in February 2021, I hiked the loop trail consisting of…read moreBolinas Ridge Trail, Jewell Trail, and Cross Marin Trail. My hike was in the counterclockwise direction around this loop trail. The final stretch of this loop hike requires hiking within the narrow space between the Francis Drake Blvd. and a steep downhill slope covered with trees and with lichens called "old man's beard."
Jewell Trail has two trailheads. One is located on Bolinas Ridge Trail and the other is on Cross Marin Trail. The trailhead for Bolinas Ridge Trail is next to Francis Drake Blvd., one mile east of Olema. The trailhead on Cross Marin Trail, is situated one mile to the northwest of the Camp Taylor campground. Regarding the Bolinas Ridge trailhead a mile east of Olema, typically between five and ten automobiles are parked here. They're parked on the south shoulder of Francis Drake Blvd., but additional parking places are available on a wide dirt shoulder, across the street and 50 feet to the west.
The segment of Bolinas Ridge Trail leading to the Jewell Trail Trailhead provides scenery of amazing beauty. The photographs in the following list describe, by way of pictures, everything that I could possibly describe with words about Bolinas Ridge Trail and Jewell Trail:
(1) Photo of wooden maze that allows passage of people, but prevents cows from passing through. The body of the cow is not flexible in the same way that snakes are flexible. If cows were flexible, they could be taught to dance the hula. But cows are unable to do hula dancing. Because cows are not flexible, they cannot pass through the wooden maze.
(2) On the left side of Bolinas Ridge Trail, you can see a cluster of trees sitting on a hillock, with a row of stones embedded in the hillock. This hillock occurs about 100 feet down a grassy slope.
(3) Same cluster of trees sitting on a hillock, where photo shows a tree coated with "Old Man's Beard" lichens.
(4) To the right of Bolinas Ridge Trail is a deep valley. The boulder at the far left has lichen clinging to it.
(5) On the right side of Bolinas Ridge Trail is a tall boulder with a stone shelf on it. On this stone shelf, I posed my mountain goat. While taking this photograph, a man and woman, in their 20's, were hiking by. I turned to them and said, "Don't worry, my permit for keeping the mountain goat is all paid up." They responded with a flurry of laughs.
(6) Same boulder, with both Strawberry Shortcake and the goat.
(7) Photo of deep valley to left of Bolinas Ridge Trail. Jewell Trail is just beyond this valley.
(8) Photo of the sign at the trailhead for Jewell Trail. Two men were approaching, riding their mountain bikes. I was impressed by their ability to ride up the steep hill and I said, "You are certainly strong and powerful, but I know you are vulnerable to KRYPTONITE." They understood my joke and laughed.
(9) After a minute of hiking down Jewell Trail there's a huge boulder to the right. Photo of the goat, California quail, and northern flicker sitting on this boulder.
(10) Further down Jewell Trail, view looking uphill at the beautiful upper part of the valley.
(11) Same location by Jewell Trail, with view looking downhill. Francis Drake Blvd. can be seen in the distance.
(12) Further down Jewell Trail, the forest begins. Goat and Strawberry Shortcake stand near a zig-zag in the trail.
(13) Further on down, the trail enters a shady area, covered with a tunnel of trees. I arranged a fallen white-colored branch, possibly from a birch tree, so that it would show up in the photograph.
(14) Photo of a mossy tree covered with a few tiny ferns, located next to Jewell Trail.
LICHENS. In many areas of your hike, you will find lichens hanging from trees and lichens growing on rocks. The kind of lichen that hangs from trees is "old man's beard," also called beard lichens of the genus Usnea. Photographs of beard lichens are available from, "pointreyesnature dot com/alamea-trail" and also from Kundsen and Carlberg (2005). Other kinds of lichen at Bolinas Ridge include Rimularia insularis and Rinodina falvosoralifera. Colorful lichens that grow on rocks include, Xanthoria elegans, Rhizoplaca melanopthalma, and Saxicolous lichens.
