| 説明 | Lovelock Cave (NV-Ch-18) is a North American archaeological site previously known as Sunset Guano Cave, Horseshoe Cave, and Loud Site 18. The cave is about 150 feet long and 35 feet wide. Lovelock Cave is one of the most important classic sites of the Great Basin region because the conditions of the cave are conducive to the preservation of organic and inorganic material. The cave was placed on the National Register of Historic Places on May 24, 1984. It was the first major cave in the Great Basin to be excavated.The large rock shelter is north of modern day Humboldt Sink. Lovelock Cave is in the Lake Lahontan region, next to the former lakebed of Lake Lahontan. It was formed by the lake’s currents and wave action. It was first a rock shelter. Eventually an earthquake collapsed the overhang of the mouth. Lake Lahontan was a large Pleistocene pluvial lake that covered much of western Nevada. Due to drier Holocene climate the water elevation dropped and much smaller lakes remain such as Humboldt Lake, Pyramid Lake, and Carson Lake. The dry environment of the cave resulted in a wealth of well-preserved artifacts that provide a glimpse on how people lived in the area. Lovelock Cave was in use as early as 2580 BC but was not intensely inhabited until around 1000 BC. People occupied Lovelock Cave for over 4,000 years. The initial discoveries of artifacts and excavations, in the early 20th century, were not very well executed, which resulted in a loss of archaeological information. However more recent investigations were more careful and meticulous. A wealth of knowledge pertaining to life on the Great Basin has come from this important site because many unique artifacts have been successfully recovered.The most renowned discovery at Lovelock Cave was a cache of eleven duck decoys. M.R. Harrington and L.L. Loud found when they were digging for the Museum of the American Indian in 1924 in Pit 12, Lot 4. The cache included eight painted and feathered decoys and three unfinished decoys. Items found in the same pit consisted of feathers and two bundles of animal traps. The remarkable decoys were made from bundled tule, a long grass-like herb, covered in feathers and painted.en.wikipedia.org/wiki/Lovelock_Caveen.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
