Sonora Pass Carcamp Trip Report (Aug 1-3, 2008)

by Carolyn Dorsch

Eighteen people, including trip leaders Stella Yang and Carolyn Dorsch headed up to the Sierras the first weekend of August.  We camped off of Hwy 120, at 6,200 feet, near the Clark Fork of the Stanislaus River.  The first day we stayed in the “lowlands,” and explored along the Clark Fork meadow and the Column of the Giants. 

Day Two found us up near the top of Hwy 120, just a little west of Sonora Pass.  We spent the day hiking up to St. Mary’s Pass (10,100 feet).  The walk was steadily uphill, but with wildflowers all along the way, low 70s temperature, and nice breezes, the 1,200 foot climb from the trailhead was quite manageable.  Along the way, and at the top of the pass we found many high-elevation flora blooming, including the following:  Pursh’s wooly-pod (Astragalus purshii), Buckwheat (Eriogonum ovalifolium), Sierra Claytonia (Claytonia nevadensis), and Arctic Willow (Salix arctica).  In fruit were two anemones: A. occidentalis and A. drummondii.  All together, it was about a three-mile round trip.  A couple people took the challenge offered by the mountains, and continued their hike up to Stanislaus Peak (11,233 feet) before rejoining the group back at the trailhead in the late afternoon.

Day Three, as a final stop before heading home, we drove down Herring Creek Road.  While it can be stunning in June (elevation around 7,000 feet), we had to work harder to find the flowers.  Following the water, we came across beautiful colonies of Alpine Lily (Lilium parvum) near Herring Creek. The trip was capped off with a short visit along the Trail of the Gargoyles, where we could admire the amazing geologic formations.  Plans are already in motion for another trip up to the Sonora Pass area. 

Late June/early July is the best time to see the flowers at the 6-7,000 feet elevation, but there is plenty to see in early August, so long as you go to the higher elevations. Look for this trip’s highlights at a Member’s Night meeting later in the year!

CNPS Santa Clara Valley Chapter Field Trips

IMG 7822 dee stella ken pinnacles 640pxChapter field trips are free and open to the public.  Field trips are oriented to conservation, protection and enjoyment of California native plants and wildlife.  A list of past field trips and reports can be found here.

Many other upcoming chapter activities are listed in the Blazing StarYou can also find many of our chapter field trips and other activities on our Meetup Group.  Signing up on Meetup allows the trip leaders to send notifications in case of changes or cancellations.

In our region it is important to be prepared for hiking on rugged and steep terrain, wide temperature ranges and rapidly changing conditions at any time of year. Our hikes are often slow with many stops and standing around for long periods. All participants should wear sturdy footwear and carry sufficient water, sun protection, food, clothing layers, personal first aid and other supplies you may need. Also bring hand lens and binoculars for viewing plants and fauna.

Cell service is mainly restricted to cities and major highways. On your way to an outing do not rely solely on your phone. If you have any questions about your ability to participate in a particular field trip, please contact the trip leader in advance.

 


SEPTEMBER 2022

Sat Sep 24, 9am-1pm Oaks of Edgewood (San Mateo County)

Join Paul Heiple and Ken Himes to learn about the five species of Quercus, the true oaks, that occur in EdgewoodCounty Park and Natural Preserve.

Our oak hike will be along a partial loop of about 4 miles on the Clarkia Trail, Serpentine Trail, Sylvan Trail, and Live Oak Trail to see the scrub oaks.

In addition, we’ll see at least two hybrid oaks. Hopefully, we will have a good crop of acorns to help with oak ID. We’ll also feature oak galls, which are another aid to identify oaks. Bring a hat, sunscreen, water and snacks. Wear sturdy footwear. Bring a hand lens or loupe if you have one.

We’ll meet at the Clarkia trailhead across the parking area on Cañada Road at 9am sharp. Careful when crossing road. Parking is across the street, see parking map.

This hike is open, no need to register but go to our meetup for further hike details and directions, here.

NO PETS OR DOGS PERMITTED IN EDGEWOOD PARK. 

This hike is also very slow paced looking at various plant life and enjoying nature.

We hope this date will coincide with early Sierran blooming flora, with possible purple fawn lily (Erythronium purpurascens) at Grouse Ridge Lookout peak. We will have two full days of exploration, which means three nights camping. We’ll park our cars at a nearby trailhead then backpack less than 2 miles, with a 300-foot climb, to our campsite.

This trip is for CNPS members only (please ensure your membership is up to date or join). Space is limited and registration is required.

Finally, at the area’s margins, redwoods and ferns make their presence.

Several species of manzanita will hold our interest. Bring lunch, snacks, and recommended 2+ liters of water. This hike is open to all comers, with no registration needed.

Sat, Aug 7, 9am - noon, Tour of the Regional Parks Botanic Garden (Tilden Park, Berkeley)

Join East Bay Regional Parks Botanic Garden director Bart O’Brien for a walk through the state of California within the garden’s 10 acres. This early August walk will highlight some of the botanic garden’s newly added areas. We expect to see a variety of summer blooming plants such as wild buckwheats, late penstemons, evening primroses, gum plants, scarlet larkspur, Milo Baker's lupine, and some beautiful alpines in our new crevice garden to name a few. Bring a lunch and have it on the lawn after the tour. Please note there’s no public access to the buildings at the moment.

This field trip is open to CNPS members only due to the limited spaces available. No drop-ins. Attendees must sign up in advance.


Photography Group

Our Photography Group is a great place to meet other native plant enthusiasts while improving your photographic skills and learning more about our native plants. It is open to all. The group has periodic meetings, photography outings and an active email list. The group has an on-going #MyPhotoOfTheWeek activity on the email list for group members to share their favorite shots with the group on a weekly basis. There is a monthly virtual meeting on zoom on the fourth Friday of each month for members to share photos and more -- everything from photography tips to organizational ideas to plant hot spots.

Our upcoming events can be found on Meetup and Facebook. Past events can be seen here.

To participate in our virtual activites, we recommend that you join our online discussion group

Anza Borrego State Park - March 6 - 13, 2016

By Dee Wong, Field Trip Chair

bighorn sheep anza borrego lohseCo-leaders Patricia Evans and Joe Cernac took 17 hearty souls (including CNPS fellow Sally Casey, age 94) on a trip to the desert, despite forecasts of rain. After arriving in Anza Borrego on Sunday March 6, the trip started in the rain Monday with a stop at the visitor center. Two days of sunny hiking followed in Palm Canyon and Culp Valley. Many of the highlights were seeing the desert peach, desert apricot, and desert almond all on the same day. We also saw five bighorn sheep which the state park is partially named after, Borrego, and hundreds if not thousands of sphinx moth caterpillars of various instars (molting phases) devouring the brown-eyed primrose and sand verbenas. Dee Wong even saw one that was digging a hole in preparation for pupating.

asclepias-fascicularis-narrow-leaved-milkweed-closeHike #2 was to see the progression of drought effecting Stile Ranch. There were 11 attendees including the co-leaders Stella Yang and Dee Wong, and Ken Himes as sweep. As the weather heated up without much winter rains, the grasslands along the trail had already started drying out and turning gold and silvery in color. The native grasses such as Elymus glauca, Melica californica and Melica torreyana had begun to set seeds. With most spring wildflowers finished flowering, the summer flowering plants that were in bud (during hike #1) were now flowering, such as the Monardella douglasii, Streptanthus glandulosus var. glandulosus.
