The Hopewell Rocks, also called the Flowerpots Rocks or simply The Rocks, are rock formations caused by tidal erosion in ''The Hopewell Rocks Ocean Tidal Exploration Site'' in New Brunswick. They stand 40–70 feet tall. They are located on the shores of the upper reaches of the Bay of Fundy at Hopewell Cape near Moncton. Due to the extreme tidal range of the Bay of Fundy, the base of the formations are covered in water twice a day. However, it is possible to view the formations from ground level at low tide.〔As the tides are best seen at low tide; check the Hopewell Rocks website for tide tables.〕 The formations consist of dark sedimentary conglomerate and sandstone rock. The large volume of water flowing in to and out of the Bay of Fundy modifies the landscape surrounding it. After the retreat of the glaciers in the region following the last ice age, surface water filtering through cracks in the cliff has eroded and separated the formations from the rest of the cliff face. Meanwhile, advancing and retreating tides and the associated waves have eroded the base of the rocks at a faster rate than the tops, resulting in their unusual shapes. The vast sediment planes in the basin in Fundy supports a variety of biological productivity. Various shorebirds are often seen flocking to nest and feed in the area. Visitors are advised to stay for a full tidal cycle to get a full appreciation of the tides and formations. Although the tides vary from day to day, the high tide can be as high as giving the Hopewell Rocks one of the highest average tides in the world. ==Notes== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Hopewell Rocks」の詳細全文を読む スポンサード リンク
