Trip Report: by David Takeuchi
Five NSAS members met Terri Bostater, Naturalist at Sunol Regional Wilderness. Terri gave us an introduction to the Sunol which is part of the East Bay Regional Park District. Also joining us was Dana Flores, Naturalist Intern. The park attracts many hikers, including families. We started our walk, crossing a bridge over Alameda Creek. Pat Heldrith pointed out a thrush which turned out to be a Hermit Thrush. We walked through the riparian picnic grounds, bring back memories of past NSAS field trips. The flowing stream under oaks , birds calling and the easy access to parking is why we have selected to had gourmet picnics in this wooded area in the past. The morning was sunny and cool, and as the hike progressed later in the morning, jackets were shed. The hills were green from the winter rains and the coming of spring attracted birds, singing their repetitive songs. Orange crowned warblers called to us during our gentle hike to Little Yosemite. Red-shoulder hawks cried throughout the canyon as they circled with the thermals. Wildflowers were scattered along the trail, and provided Dana the opportunity to takes photos. There were plots of shooting stars and wild pansy, also known as Johnny Jump-ups. Mike Moshier also took photos, but his was of birds. A small bird called to Cheryl Harris as it darted across a fallen log. It turned out to be a Bewick Wren. The waterfall as Little Yosemite was more like a back yard waterfall than the rush of water that follows a heavy rainfall. The massive boulders lend its name to Little Yosemite. A family with two young children enjoyed the pool of water below the falls. It was evident this was not their first time to visit the pool. They passed us on the way to the falls, which by the way is not marked with a sign. The creek flowed crystal clear, and during the warm summer months will be an inviting attraction to dip your feet and cool off. We ate our lunch at a picnic table under canyon oaks, before heading back. I stopped at the Visitor Center. The snakes were asleep, and the female tarantulas has come out of her borrow for a drink of water.
