Ursa Minor Cave is a part of Sequoia National Park, a naturally formed system of caves in the famous Sierra Nevada region of California. It was discovered in August 2006 by explorers from the Cave Research Foundation. They widened the hole to facilitate human entry and found one of the US’s most beautiful and unique caves.

Ursa Minor Cave, California 

Ursa Minor has a cave lake around 100 ft across and vertical drops that should be traversed using ropes. There are several passages inside the cave, but the actual length of the cave is still unknown. The new cave is closed for recreational visits till scientific study is complete.  

History of Ursa Minor Cave

Four amateur cave explorers in Sequoia National Park have discovered a massive cave formed 1 million years ago. It is a labyrinth that stretches for more than 1000 ft into a mountain, and it has fantastic rock formations ever seen in the world. Millions of crystals shimmer like diamonds, and the flowstones look like spilled paint over the floor.

There is a lake that is 20 ft deep and fills one of the five known rooms in the cave, and the passages lead to utter darkness, thereby suggesting that there is more to see in the cave. The discovery of the caves has managed to excite the geologists; although caves have been discovered in Sequoia National Park with reasonable regularity, this cave is the grandest of all. It is believed that the caves will open the doors for detailed geological study.

Geological Cave Formations in Ursa Minor Cave

The cave has large passages and rooms, and most of these are more than 50 ft in width. They have beautiful cave formations such as long cave curtains, soda straws which are fragile and up to 6 ft in length, and huge areas of multicolored flowstone.

The cave curtains were formed by water flowing from overhangs. Some of these curtains are translucent, while others are red, brown, or orange. There are also cave pearls which are nothing but calcified balls of sand that are of the size of large tomatoes. 

Wildlife in Ursa Minor Cave

No specific information is available on the kind of wildlife found in the caves.
