The Natural Wonders of Glen Canyon

Leader: Paul Bouscal, California Naturalist

Join us on a spring hike to explore this canyon in the midst of residential neighborhoods. Glen Canyon is one of San Francisco’s significant natural resource areas containing a variety of vegetation including forbs, grasslands, shrubs, willows and other trees. At this time of year we hope to see spring wildflowers in bloom.  The park features rock formations, and it is the source of Islais Creek. We will walk and view parts of this 70-acre park to enjoy the flora, fauna and natural history.

Meet at Elk and Chenery Streets. This is approximately a 10-minute walk from the Glen Park BART station.  The 44 bus also stops nearby. In San Francisco layers of clothing are recommended. Heavy rain cancels.

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 then descend to the parking lot through Cable Ravine. Otherwise, we’ll bail out at Battery Road 59 and descend Radio Road. 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.

San Bruno Mountain: Ridge Trail

Leader: Doug Allshouse

Come spend the day walking the Ridge Trail which follows the San Bruno Mountain ridgeline. The trail offers a long and interesting menu of plant species including the endemic SBM manzanita, several paintbrushes, Franciscan wallflower, two wild cucumbers, three lupines, stonecrop, coast rock cress and more. On a very clear day the vistas extend from Pt. Reyes to the South Bay and from the Farallones to Mt. Diablo. Its topography begins in Franciscan coastal scrub, blue blossom chaparral and coastal terrace prairie, and then transitions to needlegrass grassland the further southeast we travel. The wildflower show, while varied and spectacular, is just part of the allure. If weather permits, we probably will encounter the endangered Mission Blue butterfly, along with other spectacular species such as Anise Swallowtails and Green Hairstreaks. An autumn 2018 grassfire near the East powerline should hopefully offer some fire-follower wildflowers. The entire out-and-back trip is about 4 miles over a rocky and undulating fire road with frequent elevation changes. Bring a lunch and water. The $6 entry fee is payable at the kiosk to a ranger or the cash or charge pay station. Turn right at the stop sign and follow Radio Road up to the summit parking lot. The mountain offers box-of-chocolates weather so bring layers. Heavy rain cancels. Any questions, directions or weather reports contact Doug at dougsr228@comcast.net or 415-269-9967.
