Sizer the highest point), Rock House Ridge, Bear Mountain, Bear Mountain Peak, Robison Mountain (not Robinson Mountain as it is too often misspelled), Rooster Comb, Palassou Ridge, Mahoney Ridge (and Mahoney Meadows), Willow Ridge, Pacheco Ridge, Mustang Peak, Walsh Peak, Willson Field Hill, Wasno Ridge, Burra Burra Peak, Willson Peak, Rock Springs Peak, and Phegley Ridge. The park is divided into 13 zones on the official map. From West to East, and North to South, they are: Western Zone (Park HQ) Blue Ridge Zone (Mt Sizer, Hat Rock) Interior Zone (Bear Mountain) Mississippi Zone Orestimba Wilderness Zone Mustang Peak Zone Mahoney Zone Coit Zone Pacheco Zone (Dowdy Ranch Entrance) Grizzly Gulch Zone Kelly Zone Dormida Zone Phegley Zone (Bill's Hill, Redfern Pond) The park map also shows 1) Thomas Addition (near Mt. Sizer) and 2) Lakeview Addition (just below the park's HQ) to which there is no public access as of now (late 2013), nor any plans yet to make those areas accessible to public. The area encompasses parts of three major watersheds: Coyote Creek, Orestimba Creek, and Pacheco Creek. Coyote Creek is fed by Grizzly Creek, the Little, Middle, and East Forks of Coyote Creek, Kelly Cabin Canyon, Grizzly Gulch (not be confused with Grizzly Creek), and Hunting Hollow. Coyote Creek flows into Coyote Lake and Anderson Lake, and then north through San Jose into the San Francisco Bay. The South Fork Orestimba Creek originates in the park, and is fed by Red Creek, Pinto and Robinson creeks, and Lion Canyon. After joining the North Fork outside the park, it flows out to the San Joaquin Valley, where it joins the San Joaquin River. The latter runs more or less north and, if it were not diverted, would flow out to San Pablo Bay. The North Fork Pacheco Creek also originates within the park, and it is fed by Mississippi Creek. Cañada de la Dormida independently reaches Pacheco Creek outside of the park boundaries. If not diverted, the waters of Pacheco Creek would eventually reach Monterey Bay via the Pajaro River. There is a fourth, minor watershed within the park: the small creeks of the Upper San Antonio Valley in the north flow into San Antonio Creek north of the park. This, in turn, joins Arroyo Valle, which flows into Alameda Creek, then flows into San Francisco Bay west of the city of Fremont. The creeks are all seasonal;
