Little Brush Creek cave, Utah
Little Brush Creek cave is located in eastern Utah. Little Brush Creek Cave has been publicly mapped for around 5.9 miles but additional survey has rendered passage that has extended this cave to 7 miles making this cave the longest cave in Utah.

This cave has a short visitation span of only a few month in the winter due to the massive amount of water that this system takes in from Little Brush creek.  The river loses right into the cave and nobody has found where the water goes as of yet.

A winter visit into this cave is the best time to go so you are not caught in a flash flood and so you can traverse around the frozen potholes that are full of water.

The first 200ft of passage is massive borehole which is all within the light zone in the entrance room.  There is a dome room to the left which is around 40ft high and 30-40ft long.

Laura and I encountered a lot of rotting logs and debris that  have been keyed in from previous floods that creates a lot of obstacles for a continued pursuit into the cave.  Small tiered climb downs, 3ft. to around 6ft., with air sucking into the cave, tell an obvious tale that this cave holds an extensive labyrinth of passage.

There are some restrictive passages where logs that can be difficult to go through, but with a little thought, they are straightforward to breach. Continuing down the cave the room will get slightly bigger with less stoop walking and more walking until you get to the pothole canyon passage.

We found this to be interesting as the limestone was a strong reinforced strata with conglomerate stone at its contact and in the ceiling.  It was a rather gray light pale, to blue gray in color with some yellow staining sprinkled in. I made it almost a mile and decided to turn around as daylight was burning on the topside and I wanted to check on Laura and check on a few out side passages.

The cave was a balmy 35-40 degrees as it was 15 degrees outside which made this feel quite warm as long as you kept moving.

After exiting the main corridor I found a side passage that was blowing out to the exit which was a quick realization that a possible through trip can be made in this cave. Back in the Midwest, the caves where usually blowing out or sucking in depending on the season but in this cave system the cave was doing both. We noticed the ice hexagonal ice crystal on the other entrance which were beautiful!

We found this crystallization to be quite interesting because of how the prisms should shimmer in all different direction making these a little challenge to photo. This also shows the the cave has air circulation properties.

I was able to find a crack that was bolted and appeared to be quite deep but unfortunately I did not have my vertical gear with me so I was not able to get down there.

Toothbrush cave was right next door which is a walking entrance with a breakdown slide to a 40ft pit that drops into walking passage for a couple hundred feet.  We are going to bring my vertical gear next time for that one.
