Del Norte

Note: due to surveying errors, the California/Oregon state boundary is not exactly at Latitude 42, and there is technically a tiny sliver of Grants Pass, Oregon inside Del Norte County. This sliver is less than 150 meters wide at its greatest extent.

That bit of Tehachapi, California is small, and at the ridgeline of the Sierra Nevada mountains. Good luck!

34,-119 34,-118 34,-117

Los Angeles

34,-118 34,-117
33,-118 33,-117
32,-118


Editor's note: San Clemente Island will probably have to be achieved by boat as the island itself is owned by the US Navy, regardless Wikipedia says it is Los Angeles County so you must succeed in this graticule to claim the LA regional achievement. Please refer to the San Clemente Island Website for information and exclusion zones. Please read and understand SCI Safety Zone Procedures before approaching the island.

Madera

37,-120 37,-119
36,-120 36,-119

Marin

38,-123 38,-122
37,-123 37,-122

Note: The bits of land within Marin County in the Bodega Bay and Farallon Islands graticules are really, really tiny. They're reachable, but the odds of a hashpoint falling in them is low.

San Francisco

Good luck with the Farralon Islands graticule. The Farallon Islands are part of a National Wildlife Refuge, with access restricted to the public. The rest of the graticule is either water, or part of Marin County, or not in any county.
