San Bruno Mountain: Summit Trail

Leader: Doug Allshouse

The Summit Trail is a very popular and spectacular 3-mile loop that stretches over the northern portion of the mountain and is the most species-rich trail. It passes through a logged eucalyptus forest and descends past active seeps until it reaches April Brook. We’ll see horsetails, fringe cups, iris, coast rock cress, and at least five ferns. From there we head up to Bitter Cherry Ridge with rocky outcrops covered with fog lichens and views of the ocean and the Daly City dunes. If we have time we’ll check out Kamchatka Point and some endemic manzanitas and huckleberries then descend to the parking lot through Cable Ravine. Elevation gain on the trail is about 700 feet. There is a $6 entrance fee (cash, credit/debit card) payable at the pay station.

Meet at the parking lot on the other side of Guadalupe Canyon Parkway by turning right at the stop sign just past the kiosk/pay station and follow the road under the parkway. Bring a lunch and layers of clothing because, due to the marine influence, the weather is a box of chocolates; you never know what to expect.

Heavy rain cancels. Contact Doug at dougsr228@comcast.net, or call/text 415-269-9967 if you have questions.

Biodiversity Big Walk and Bioblitz

Leader: Bob Hall

This hike is part of the City Nature Challenge (http://citynaturechallenge.org) where thousands of people from across the globe will get outside to look for nature in their cities. The hike will be fairly strenuous and will stretch from Glen Canyon to the Golden Gate Park Oak Woodlands. We will use our smart phones to catalogue biodiversity on the way.

Meet outside the Glen Park Rec Center. Bring a lunch and a smart phone with the iNaturalist app.

Heavy rain cancels. Contact Bob at bilgepump100@sbcglobal.net if you have questions.

May 4, SATURDAY 11am- 1pm

Sign Hill - Butterflies and Wildflowers, oh my!

(What's not to love about this one? 🙂

Leaders: Liam O'Brien, Loretta Brooks and Chuck Heimstadt

We will walk at a leisurely pace, but due to the uneven ground and steep trails, we recommend wearing sturdy shoes and long pants.  Meet Saturday morning (11am) at Sign Hill's west entrance:  from Oyster Point off 101, go west on Hillside/Sister Cities Blvd., turning off Hillside to Stonegate Drive and continue uphill to the left to Ridgeview Court with the cross street Carnelian at the end. There is a small parking lot there and street parking on the way up, and if necessary the Elks lot may be used for this short time.  You may consider carpooling with friends.  A forecast of wind or rain cancels until the next Saturday, May 11th.  Please leave pets at home for this walk.

No need to sign up but please contact  "chuckheimstadt@yahoo.com"  with any questions.

Liam O'Brien is San Francisco's well-known lepidopterist, artist, illustrator, and Bay Nature's award-winning environmental educator.

Loretta Brooks and Chuck Heimstadt live on the edge of Sign Hill and have become its ardent stewards, and participants will benefit from their collective knowledge and enthusiasm.

We expect to see plenty of wildflowers with beautiful vistas, not to mention butterflies.  A large portion of this grassland is protected with Sign Hill Park and the recently donated and acquired Friends of Liberty Park, but the other 26 acres, equally worthy of preservation, are privately owned and vulnerable to development.
