Cosmic Cavern is a limestone cave located in north Arkansas, near the town of Berryville, Arkansas. One brochure for the cave touts it as "Arkansas' Most Beautifully Decorated Cave." It is the "warmest" cave in the Ozarks, having a high humidity holding at a constant 62 degrees year-round. Most caves in the area are between 55° and 60°. The cave has an abundance of formations (speleothems), including stalactites, stalagmites, flowstone, cave popcorn, cave bacon, and a multitude of soda straws and helictites. One section of the cave housing a particularly spectacular group of soda straws has been dubbed "Silent Splendor." One of the longest soda straw formations in the Ozarks, this large formation has straws hanging up to nine feet in length. ==Lakes and life in the cave== Cosmic Cavern has two cave lakes reported to be bottomless, since cave divers have never found the bottoms. They are among the largest underground lakes in the Ozarks. The south lake was artificially stocked with trout in the 1920s, and many of the remaining trout have become blind and have lost their pigmentation; however, there are openings to external water bodies, as trout from the cave are occasionally found in nearby surface bodies of water. Rainfall is known to dramatically change the water level in the cave, which can fill and empty rapidly. Other life in the cave includes the Ozark blind salamander. This salamander is endemic to the Ozarks, where it is found in several caves. It is related to the Olm (''Proteus anguinus''). Though there are also crawdads in the cave, these are not believed to be native. 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「Cosmic Cavern」の詳細全文を読む スポンサード リンク
