This plateau is also a great place to see another formation, the freshwater lake. Maricich Lagoons, just southeast of the junction of Spengler and Old Briones Road, is a breeding ground for California Newts in the spring. The lagoon at the junction of Briones Crest and Lagoon Trail is a great place for waterfowl such as Buffleheads, Mallards, Canvasbacks, and the occasional Merganser. Usually you can find Western Pond Turtles sunning on the sheltered logs protruding in the lake, and the banks are full of tiny Pacific Treefrogs, and the occasional threatened Red-legged Frog. From here you can make a scenic loop on Lagoon Trail in the John Muir Nature Area, or perhaps follow Briones Crest for a big loop around the park.
Maps are usually available at the gate.
