October Events in Claremont Canyon

Saturday October 20 in Garber Park  Please join us as we continue our fall clean up. Meet at the Claremont Avenue entrance at 10:00 AM. We will work til Noon. We will start by attacking the Algerian ivy just above Claremont Avenue. A short distance up the trail is beautiful Fern Glade where we have ongoing work removing the ivy to give the ferns a chance to grow once the rains come. Alternatively, you can join us further up toward the Evergreen Lane entrance where we will be cutting and pulling invasive weeds above the fireplace. Also, the trail crew will be clearing the trail and making improvements with your help. 

We provide tools, gloves, water and snacks. Directions: From the intersection of Ashby and Claremont, go .4 miles up Claremont to the Claremont Avenue entrance to Garber Park. For more information, a map and directions, visit or contact Shelagh at

Saturday October 27 in the Upper Canyon Join us at 10:00 at Signpost 29, our usual gathering place 1.5 miles up Claremont from the intersection with Ashby Avenue/Tunnel Road. We will work til Noon or 1 PM. Bring a bottle of water and we will supply the tools. We plan to make improvements to the Gwin Canyon Trail. We are happy to report that hikers are discovering this relatively new trail. We will continue to make it easier to navigate.

Saturday, December 8—The Birds of Claremont Canyon, 8-11 AM, led by Dave Quady, Audubon Christmas Bird Count Leader for Claremont Canyon.

Join us to look for winter birds in Claremont Canyon. Dave will also lead a special owling adventure in the wee morning hours, followed by a break for breakfast. Join us for one walk or both.

Owling (December 8), 4:30-6:30 AM. Meet at the trailhead on the north side of Claremont Avenue (Signpost 28), about one half mile uphill from the Alvarado Road intersection. After a brief owling lesson, we’ll listen for owls at a couple of locations in the canyon. We will walk a little, but mostly stand quietly in the dark and listen. Owling is chancy: we hope to hear an owl or two; if we’re lucky we may see one. Rain or high wind cancels.

Daytime Bird Walk (December 8), 8 AM. Meet at the top of the canyon at Four Corners (the Claremont Avenue/Fish Ranch Road/Grizzly Peak Boulevard intersection). We will drive to a couple of locations to sample different habitats in search of resident and migrant birds. Rain or high wind cancels.

Call Dave at 704-9353 before 9:00 PM on Friday, December 7 if you’re unsure whether the walks will run in light of the next day’s weather forecast. Dress warm- ly and bring binoculars, eld guide and ashlight (for owling).
