The Oregon High Desert Grotto (or OHDG) is an American caving club, known as a grotto. It is affiliated with the National Speleological Society. OHDG is involved with caving and conservation efforts in central Oregon and beyond, including the Oregon Caves National Monument,〔 (【引用サイトリンク】 date = August 31, 2009 ) 〕 the Lava Beds National Monument in northern California,〔 〕 and caves in western Idaho and southern Washington. Members of the grotto have worked with the Department of State Lands and received a participation award from state leaders for their volunteer work.〔 〕〔 〕〔 〕 In 2013, the grotto was recognized by Region 6 of the United States Forest Service for various volunteer hours working with caves and bats. They received the R6 Volunteers and Service and Program Award.〔 〕 == History == The Oregon High Desert Grotto was first created in 1989 by Dan Best.〔 〕 It lasted only a year before complications terminated the grotto.〔 〕 In late 1995, the OHDG was reformed by the new founding member Ric Carlson, who was at the time an employee of the forest service.〔 〕 By 1997, the Grotto had over 30 members, a newsletter publication, and a growing knowledge of caves in the Central Oregon area and beyond.〔 As of 2012, the OHDG continues to find new caves. Grotto member Matt Skeels has found over 100 new caves.〔 〕 Today, the grotto is actively involved with caving in most of Oregon and the adjacent states.〔 〕〔 〕〔 〕〔 〕 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「Oregon High Desert Grotto」の詳細全文を読む スポンサード リンク
