As one lady shouted out: all the delicate formations that took thousands and thousands of years to develop are still intact… so it must be safe to be underground. Interestingly, during the tour, we also learned that it’s safest to be underground during an earthquake. The fact that they exist prompted officials to label the cave a National Natural Site (NNS) in 1975 and preserve the contents within. Also found throughout this area are helictites, which are both delicate and extremely rare. At the end of this large chamber is a backlit flowstone under which many have proposed to their future spouse we opted for a simple photograph. The most elaborate and beautiful part of the cavern walk is the Landmark Room. People are suitably warned ahead of time… repeatedly… but it still happens. that fall from pockets as people lean over to get a better look. Luckily, this is the only formation in the cave that sustained damage before people realized that it wasn’t going to grow back in anyone’s lifetime.įurther along the walk, you get a glimpse of a beautiful underwater lake that has swallowed more than its fair share of cameras, flashlights, lens covers, car keys, glasses, etc. Near the entrance is one very large formation that early adventurers liked to chip away at in order to get souvenirs, not realizing that it takes hundreds of thousands of years for each one to form. The formations are pretty and very interesting, narrow and steep steps, but doable. This particular cave is full of interesting geological structures that photograph well: stalactites, stalagmites, columns, flowstone, draperies, ribbons, angel’s wings, cave bacon, soda straws, and helictites. So, we opted to meander through the Black Chasm Cavern as a tourist in lieu of dangling from a rope. Our intended goal for visiting any one of these caves was spelunking (as part of the outdoor adventures theme) but quickly realized in the investigation phase that La Niña doesn’t meet the requisite 100lbs and no amount of pizza and guacamole covered french fries would help her get to that point in one summer. Cave speleothems are generally formed by dripping or splashing water, but helictites are formed through hydrostatic pressure. It has been open for public tours since 1998. All are equally interesting and have a caving adventure component. Black Chasm Cavern was designated a National Natural Landmark in 1986 by the National Park Service, due in part to its incredible display of rare helictite formations. The lesser-known caves are the Black Chasm Cavern, the California Cavern, and the Gold Cliff Mine (no longer available). To me, this reads: super busy all the time. The most popular and known is Moaning Cavern Park, which incorporates other activities into their offering like zip-lining, kids climbing walls, birthday parties, and concerts in the cave. There are four Cave & Mine Adventures caves in the Sierra Mountains that are frequented by tourists.
