Emeryville Crescent State Marine Reserve is a marine reserve of California, United States, preserving marshland on the east shore of San Francisco Bay. It is managed as part of Eastshore State Park by the East Bay Regional Park District. The 103.5-acre (41.9 ha) marsh stretches from the eastern approach of the San Francisco–Oakland Bay Bridge in Oakland to the foot of Powell Street in Emeryville. The reserve encompasses the entire Emeryville Crescent Marsh and is named as such for its crescent shape. It was established in 1985. Temescal Creek drains into the marshes near the Emeryville–Oakland border on the eastern midpoint of the marshlands. The wetlands are made up of native species of pickleweed, and are currently being threatened by Spartina, a non-native invasive species of Cordgrass. It has invaded 2.4 acres (0.97 ha) or 2.5% of the wetlands. There is an active abatement...From the Wikipedia article “Emeryville Crescent State Marine Reserve”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Emeryville Crescent State Marine Reserve, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 hours on a moonless night), and the core peaks around 23° above the southern horizon. Our light-pollution model puts the sky at about Bortle 8 (city sky), so expect visible sky glow; drive away from towns for better results.
