- The 80' entrance drop to Lechuguilla and the room below had been known since the early 1900s, and were mined for guano.
- A series of digs by Colorado cavers broke through in 1986. Entrance is now through this culvert, where 60 mph winds have been recorded.
- Deep secrets, in the Western Branch, was the first arm of the cave explored. These planar coralloids mark the entrance to Deep Sea camp.
- Mammalaries or cave clouds are found in many parts of the cave, in old pool basins. These orange ones are above Lake Louise.
- The ABCs Room marks the start of the Western Borehole, the largest, most continuous passage in the cave. It extends over a mile.
- Gypsum floors much of the Western Borehole and "drilled" formations such as these are found along the trail. Note the tiny shield rock on each.
- The Three Amigos are probably the largest gypsum stalagmites in the Western Borehole.
- Passage shot about halfway down the borehole. Note the Three Amigos in the distance.
- The "Leaning Tower" is a raft cone covered with aragonite - perhaps the largest in the cave. It's found in an old pool basin.
- "Raft Cone Land" is a portion of the Western Borehole floored entirely with layers of calcite rafts and numerous raft cones.
- The Huapache Highway is one of the largest passages in the cave, just beyond Hard Daze Night Hall, a huge chamber.
- After a mile of bone-dry passage, an active area is reached at the end of the Western Borehole: the Oasis, a receding pool basin.
- Inside the Oasis Pool Room, near the top of the water line.
- Much of the pool which once filled the Oasis Chamber has evaporated.
- The Red Lake Passage is in the same vicinity as the Oasis. Note the 5' long soda straw which extends directly into the pool.
- South Winds, a complex of passage south of the Western Borehole, is noted for its impressive aragonite bushes.
- The Northwest Passage leads from the Western Borhole to Hudson Bay. I call this area of the room the "Toasted Marshmallows".
- These unusual mammilaries are found in the Northwest Passage.
- Spar City is a portion of the Northwest Passage entirely covered with large spar crystals. Note the caver peering through the hole.
- Beyond Spar City, a series of ascents on flowstone lead to the well decorated There Be Dragons region.
