Sadie River drains from the Kenai Mountains in Kachemak Bay State Park into Sadie Cove about 14.5 miles (23 km) southeast of Homer and 13 miles (20 km) east-northeast of Seldovia, Alaska. Sadie Cove is on the southeast shore of Kachemak Bay and was named in 1880 by William Healey Dall of the U.S. Coast and Geodetic Survey for Sarah “Sadie” Eldred, who was the wife of Marcus Baker.
Marcus Baker was an American naturalist, explorer of Alaska, journalist, and newspaper editor. In 1872, he was hired by William Healey Dall to be a naturalist on an expedition to Alaska, where he collected topographic and hydrographical data. He would continue to go with Dall to Alaska every year until 1888 when he co-founded the National Geographic Society and one of the first editors of the National Geographic Magazine. He was one of the 15 original signers of the articles of incorporation for the National Geographic Society in 1888. Baker was well known for his work in geology and cartography. Mount Marcus Baker in the Chugach Range of southern Alaska is named after him.
The Sadie River estuary is adjacent to Sadie Peak with a summit elevation of 4,320 feet (1,317 m) that dominates the skyline of Kachemak Bay in the Kachemak Bay State Park. The park includes 400,000 acres (161,874 ha) in and around Kachemak Bay and is the first legislatively designated state park in the Alaska State Parks system. Kachemak Bay State Wilderness Park is the state’s only legislatively designated wilderness park. There is no road access to most areas of the park, visitors normally fly in or travel by boat from Homer. Read more here and here. Explore more of Sadie River here:
