Leaders: Rich Nicholson and Bob Dunn

Big Break offers a good assortment of birds on both land and water from sparrows and warblers to ducks, grebes, and gallinules. This is an interesting new place for us to bird and well worth the hour and a half drive. We will then move on to Black Diamond Mines, which is the former site of the Hazel Atlas Mining company. Here, we'll look for Canyon Wren, quail, swifts, woodpeckers, raptors and more. Once again, these parks are well worth the effort.

Directions: To get to Big Break take Hwy 4-E to exit 30 for CA 160. Continue on CA 160 and take exit CA-4 to Stockton/Oakley. Then turn right on Main St. and then left on Big Break Rd into the park. From the south, take N. Vasco Rd to exit CA-4, then right on Main St and left on Big Break Rd. into the park. Arrive at 69 Big Break RD. Approx. 1h 30min. It is a good idea to check Google maps for your best route and to avoid traffic problems. To get to Black Diamond Mines, return to CA-4 west to Somersville Rd. Continue west up the hill to the visitor center. Parking is free.
