Virgin Cave at Kahuku 22I

Check out yesterday’s post for part one of this caving research trip.

After 22J, we headed up to 22I. Previous scouting trips noted only 5m of cave in one direction and 15m in the other; however, after staring at a choke for a while, we found a TIGHT squeeze through. We dropped into over 130m of textbook Hawaii lava tube cave and were likely the first humans to visit this cave.

I’ve done a bit of a survey of underwater caves, concept is similar for dry caves although the methods and pace are a bit different and it’s MUCH easier to communicate with other cavers. Having done a few prior survey trips, Peter and Bob entrusted me with setting stations on this trip, which means I was out front.

Delicate calcite everywhere, mostly the ceiling

P1070077

P1070082

Calcite forming preferentially on a particular side of small lavacicles, which happened to be in the lee of the prevailing cave wind we observed

Due to the young age of lava tube caves, there tends to be few flowstone features, but this cave is showing the beginnings of some in a couple places. Yay: Wet Rocks!

P1070085

Beginnings of a stalagtite

P1070087

Beginnings of stalagmites

P1070092

Flowstone deposits and WET ROCK!

P1070089

Medium-sized, mostly standing-height passage

P1070099

Lots of roots coming through the ceiling

P1070100

P1070101

P1070103

P1070105

Dramatic s-curves and elevation changes

P1070116

Lavacicles

P1070120

A flow line showing where a later flow only came part way up the tube and coated existing lavacicles

P1070121

Rather large passage that just walls out, but still good air til nearly the end. Bob looks for wind.

P1070123

The yellow-orange stuff on these lavacicles is actually a biomat

P1070124

Another flow line

P1070127

A lehua flower. Ohi’a trees are one of the first to grow on lava flows and is endemic to Hawaii.

The pics are quick & dirty snapshots taken with a point & shoot in between survey points. Peter lugged in 6 strobes and a 3D camera for the offical research documentation.

One thought on “Virgin Cave at Kahuku 22I

  1. thank you for this! I read about it, am trying to recreate the myth that explains these caves and its relations to the wai on Oahu. I never saw photos that would help me in my belief of their existence. thank you!
