Limestone at Sucia Island

We spent two days on a buoy in Snoring Bay, just east of Fossil Bay separated by Wiggins Head. According to Marianne Scott in her article entitled "Sucia, Yesterday and Today", she tells us..."Sucia is part of the Chuckanut Formation,shaped during the Eocene age about 50 million years ago after the dinosaurs disappeared,but before the Cascades were formed. The golden sandstone is the result of silt deposited by water flows and erosion in a giant, swampy flood plain that covered most of the Pacific Northwest. Many layers of sediment, along with other conglomerates, accumulated in this expansive riverbank basin, which buried many palmettos, alders and other plants. Fossils of entire tree trunks have been discovered. Successive glaciation-- the last of which retreated 10,000 years ago--further scraped and chiseled the island's surface, with many striations cut by ice and stones still visible. Wind, rain, plant roots and waves continue to sculpt Sucia's magical landscape today."
