Spearscale, pickle weed, tules, California sunflower, sneezeweed,

Saltmarsh fleabane with pink flowers, goldenrod, etc.

Directions:

We will meet at waterbird Regional Preserve, and carpool to the trail across the road.

Take Highway 24 east through the Caldecott Tunnel and drive to Walnut Creek. In Walnut Creek, drive north on I-680, past Concord and Highway 4. About two miles before the Benicia-Martinez Bridge, take the Marina Vista/Waterfront Road exit. At the end of the off-ramp turn right onto Waterfront Road, drive about 1/4 mile, turn right onto Waterbird Way, and watch for the right turn into the Preserve.
