Shell Ridge Hike with Bob Simmons - April 15st 9:00 am - 12:00 pm - Cost: $14.95

Join Bob Simmons, former Open Space Foundation President and former Mayor of the City of Walnut Creek, on a fun and informational hike in Shell Ridge and to support the Walnut Creek Open Space Foundation in its efforts to improve and enhance our open space areas. This hike will provide information on the natural resources of Shell Ridge, the history of the Open Space and the Foundation, the active restoration areas being worked by the Foundation, and some spring wildflowers. This approximately 3 mile hike through the western Shell Ridge Open Space will visit three active Foundation-led habitat restoration sites in Shell Ridge. If the hike needs to be cancelled due to rain, it will occur on the following Saturday.

This hike will start at the Marshall Drive entrance to Shell Ridge. We will start on the Briones-Mt. Diablo Trail, and continue on the Fossil Hill Loop Trail to the Sutherland entrance. On the way, we will take a short excursion on the Kovar Trail in order to stop at Indian Valley Pond to look at one of the three Foundation-led habitat restoration sites.

From the Indian Valley Pond, we will continue on the Fossil Hill Loop Trail to visit the second of the three habitat restoration sites, known as the Fossil Hill site. Here, Foundation volunteer Phil Johnson is converting the former grasslands to a beautiful array of spring follows.

From there, we will continue on the Fossil Hill Loop Trail to the Indian Creek Trail with its delightful walk along Indian Creek. At the Briones-Mt. Diablo Trail we will turn left and go uphill through Ginder Gap to the Costanoan Trail. On the Costanaon Trail, we will view from a distance the Deer Lake area, the third of the restoration sites we will visit. If the participants are interested, we can walk down and see the area. We may continue to the intersection with the Briones-Mt. Diablo Trail near La Casa Via and then return to the Marshall Drive entrance. As we will be near the end of the hike, we will take any interested participants to the top of Shell Ridge to see a possible acquisition site.

There is no age limit (minimum or maximum), but please remember that the terrain will be uneven and it is a three mile hike with some elevation gain. Please bring water and perhaps something to snack on at one of the places we will stop to talk. Please do not bring any dogs.

If we need to cancel due to rain, the hike will be re-scheduled for the following Saturday starting at the same time and place.

Sutherland Native Plant Restoration Information - 9am to 12pm
Meet at the Sutherland Drive entrance to Shell Ridge. Leader will have some tools, but please bring your own if possible. Most of what we will be doing is hand pulling, prying or slicing of taproots of mustard in short annual grasses. This is easier than it sounds. Stout, sharp knives (like a hori-hori) or similar tools work very well. Minimum age 14. For more information or to sign up write to

Indian Valley Pond Information - 9am to 12pm
Come help plant native grasses and wildflowers along around the pond while learning about the native plants and wildlife in our Open Space. We will discuss how you can use these planting techniques for native plants in your own garden. The planting days also provide a chance to see what work has been completed around the pond and what future plans will bring. We will meet at the Marshall Drive entrance to Shell Ridge. For more information or to sign up contact Sean Micallef at Plants, tools, and some extra gloves will be provided (but please bring your own if you have a pair).

Grass Planting Information - 9am to 12pm
Help the Foundation plant native grasses and do other restoration activities at various locations. Plants, tools, and some extra gloves will be provided (but please bring your own if you have a pair). Most locations are near an open space entrance, but Deer Lake will require meeting at a specified parking area and taking a short hike to the work location.
