Red Bluff Bay off of Chatham Strait is one of the most beautiful bays on Baranof Island (the island that Sitka is on). The entrance wasn't clear. It looks more like a straight cliff face than a deep entrance. The positions of the land and the depths were right-on. Pretty impressive for a survey over 100 years old. We followed the electronic charts straight in. Red Bluff has steep, fjord like walls, waterfalls, salmon streams with thousands of salmon mulling around their entrance, bears, eagles and sea lions. Truly one of the prettiest anchorages around.
