Snowy River Cave : ウィキペディア英語版 | Snowy River Cave
Snowy River Cave is a cave passage within Fort Stanton Cave in Lincoln County, New Mexico, obtaining its name from a stream bed of white calcite. == Geology == The bed of Snowy River is covered with bright white calcite. Over time, ancient, slow moving ground water dissolved the limestone walls of the cave and, with the help of microorganisms, recrystallized limestone into the white-colored mineral. Since prehistoric times, ground water saturated with dissolved calcite has periodically flooded the cave, followed by extended periods of dryness, leaving behind coatings and deposits. The Bureau of Land Management reports that Snowy River may be the largest continuous cave formation in America.
