Ursa Minor (cave) Ursa Minor (cave) Ursa Minor Cave is part of Sequoia National Park, a naturally formed system of caves in California's Sierra Nevada. The cave was discovered in August 2006 by four cave explorers from the Cave Research Foundation who found a softball-sized hole on a cliff face in the mountains. After widening the hole to allow for human entry, the explorers discovered one of the most spectacular caves in the western United States. The cave has since been named "Ursa Minor," because of the large bear skeleton found in the cave. The cave was featured in the September 2007 issue
HMS Ursa (R22) watch and there was only one minor injury. After major damage control by the ship's crew, she made her way slowly to Greenock shipyard dry dock, where she was measured for a new bow and this was fitted in under four weeks. "Ursa" returned to Devonport dockyard, where the new bow (with a stylish rake of a few more degrees than that of her original one) was finished off with standard RN fixtures and fittings. "Battleaxe" was decommissioned and scrapped. In March 1963 "Ursa" relieved in the 8th Frigate Squadron and served as West Indies guard ship from June 1963
