Bloody Creek crater
Bloody Creek crater, which is also known as the Bloody Creek structure, is a in diameter elliptical feature that is located in southwestern Nova Scotia, Canada. It is argued to be either a possible extraterrestrial impact crater or an impact structure. It lies between Bridgetown and West Dalhousie, Annapolis County, Nova Scotia, where the Bloody Creek structure straddles what was once a stretch of Bloody Creek. It also is informally known as the Astrid crater.〔〔Anonymous (1995) (''Meteor Crater, Nova Scotia.'' ) ''The Journal of the Royal Astronomical Society of Canada'' 89:111–113.〕〔Spooner I, G Stevens, J Morrow, P Pufahl, RAF Grieve, R Raeside, J Pilon, C Stanley, S Barr, and D McMullin (2009) ("Identification of the Bloody Creek structure, a possible impact crater in southwestern Nova Scotia, Canada." ) ''Meteoritics and Planetary Science'' 44:1193–1202.〕
==History==
The Bloody Creek structure was discovered by Dr. George R. Stevens, a retired geologist from Acadia University, in 1987 during a regional air photo survey. By the time of its discovery, it had been submerged beneath a reservoir, Dalhousie Lake. Dalhousie Lake was created by a dam constructed across Bloody Creek by the Nova Scotia Power Corporation as part of the Bloody Creek Reservoir hydroelectric development. As a result, the collection of rock samples from crater rim and its surroundings required the use of scuba gear and visiting the site during the occasional periods when the reservoir was drained. When the surface of Dalhousie Lake was frozen, the thick ice created a platform that greatly facilitated magnetometer and ground-penetrating radar surveys of this feature. Prior to being flooded, the interior of the Bloody Creek structure consisted of a fen within the floodplain of Bloody Creek.〔〔
