Hualalai Ranch Cave
Expeditions 2004- 2005 Trip Report ACC Home
The understanding of the size and significance of Hualalai
Ranch Cave
in Hawaii County
is becoming more and more evident with each annual expedition. It appears that
it is a world class cave in many respects and it merits protection and
management appropriate to its importance as a significant cave.
Nevin Davis reported that the cave has 15.72 miles of mapped
passage. Besides length and depth, it is significant geologically,
aesthetically, and probably biologically and archeologically. The following
preliminary summary of some of the esthetic assets will be of interest to those
who appreciate the beauty of nature.
Hualalai Ranch
Cave is a multi-level maze with
many parallel flows. One can find all the usual lava formations found in other
lava caves. It has an abundance of pukas, so one can enter the system at many
different places and, in most all cases, get to one’s work area in the cave
with less than a mile of caving from an entrance. While fountain grass, a
non-native species, dominates the surface, and goats have destroyed most of the
native plants, a few pukas have such steep walls that the goats have not eaten
the plants in them. In the deep passage
discovered and mapped this year, many black lava cycles and some with a bluish
tint, as well as a few yellow ones, were found. You can see pictures of the
original mapping and exploration of this portion of the cave at www.acave.us by clicking on “Hawaii Cave
Photos” on the blue index.
Fluff Ball Hall is exceptional for their secondary
deposition. These areas of HRC are not
awe-inspiring in the way that portions of Lechuguilla
Cave can inspire with massive
formations, but rather in an understated esthetic way that requires one to stop
and get close. A person who is not paying attention to detail might go through
Fluff Ball Hall and not think anything more about it than that it is a little
whiter than most lava caves. There are hundreds of thousands of small cave
formations that in some cases are packed so closely together that only the
outermost formations are visible. From the photographer’s prospective, it may
be too much of a good thing. A good subject that is distinct from the
background will often make a stunning picture; however, in Fluff Ball Hall most
unique and interesting formations are surrounded by, below, and on top of other
unique and interesting subjects. It is
like trying to photograph a single bee in a swarm of bees. At least the
formations are not moving, although some of the drops of water in the
formations are. As one crawls and walks through Fluff Ball Hall, the walls
appear white with some tan. The floor is also white in places and a close look
reveals that the floor is covered with small pieces of secondary deposition
that have fallen from the ceiling. One
of the best ways to see these miniature cave formations in Fluff Ball Hall is to view their pictures. You can do this at www.acae.us by clicking on “Hawaii Cave Photos”
on the blue index. In many cases the picture is better than trying to see the
original because the macro lens has enlarged the subject.
Hawaii County
could be the most cave dense area in the world, if not in cave length, at least
in the number of caves. It is not difficult to find caves, although they do
seem to be in clusters, and there are places where there are no caves at all.
Since the entire island was formed by flowing lava, I speculate that there are
no caves with natural entrances in these cave free areas because the caves that
were probably there have been blocked or filled with subsequent thin lava flows
that were too small to form lava caves. We have seen many examples in which a
subsequent lava flow went into an older cave and partially or completely
blocked cave passages.
With all the caves to discover and map, the cave mapping
takes priority. During the expedition, when a cave mapping team of three other
people was available, I was free to do photography. Photography is encouraged, as maps placed on
websites will have links at interesting places to allow people to see a photo
of the area. Sometime during the expedition there may have been only a two person
mapping team and so I switched to reading instruments to provide the third
person and left the photo equipment in the car. In these cases there were fewer
photos taken. On a few occasions, a particular area of Hualalai
Ranch Cave
was clearly so significant that it became a logical imperative to stop and
photograph it. In these cases, the three person mapping team continued mapping
and I worked alone photographing the significant features. Fluff Ball Hall was
one such place. This type of work is not for everyone in that it is very detail
orientated. It requires care to avoid harm to the fragile formations. The
photographer is likely to spend most of the time crawling, kneeling, or lying
in uncomfortable positions.
The camera equipment I used during the 2004 and 2005
expeditions was the Canon Digital Rebel D300, 6 mega pixel with the two Canon
550EX Speedlite flashes. In 2005 the Canon Macro Twin-Lite MT-24EX flash was
added for close-up work along with the Canon Macro EF 10mm lens. This combination was very effective for the
macro work in Fluff Ball Hall. This setup allowed me to work relatively fast,
even without the assistance of a second person. The earlier HRC
expeditions were done mostly with film or an earlier model digital camera that
had significant limitations. The limitation of the present system is that it is
somewhat bulky and heavy and requires a few minutes to unpack and switch
lenses. Needless to say, an assistant or fellow photographer would be helpful.
HRC expeditions have a
certain First World feel to them. While we could camp out in the fountain
grass/lava fields above the cave, all of the members have chosen to stay at
motels, condominiums, or at the Sullivan Coffee Farm. Andrea and Mark Sullivan
have been generous in providing a place for a few of the members to stay during
the expedition. The location of a few of the cave entrances to HRC
and caves such as Double Arches and Caving Goat are almost two miles walking
through a combination of lava and fountain grass to the nearest road. These
conditions provide an incentive to finish the cave work by 5:00 pm so that the walk over the lava can be done during
daylight. After the cave work is done, we are back in town to the comforts of
the Western world. These include the
convenience of discount and grocery stores, restaurants, and other amenities of
the resort town of Kailua-Kona.
The local people I have met fall into two groups, native
Hawaiians and people who have moved from other places in the US
to Hawaii. Almost everyone has
been friendly, and some people wanted to talk about the cave activities. When I
explained the cave mapping and photography and how this information could be
used to help protect the cave resources, I got two types of responses. The
native Hawaiians always thanked me for doing this work. The mainlanders were
impressed that we were doing this as volunteers and in a few cases told me the
location of caves of which they knew.
For me, 5:00 pm
cave work quitting time is time to start my other job as Marketing Director for
Marks Products, which includes answering emails and talking with customers
around the world about such topics as evaluating the cost effectiveness of
borehole camera systems in their work application. Borders Book Store in Kona
has a T-mobile hot spot connection that has really made a big difference in
efficiency and convenience of using the Internet and email. Verizon Wireless
covers Hawaii very well, so I am
not out of reach with the Marks Products customers, except when I am in a cave.
Members of the HRC
expedition in 2005 were Nevin and Judy Davis, John Rosenfeld, Kathy Haverly,
Hans Rosenfeld, John Wilson, Bruce Dunlavy and Rob Pacheco. A typical team consists of leader John
Rosenfeld recording the data and sketching, Nevin Davis using the survey instruments,
Judy Davis setting stations and reading the tape, and John Wilson doing
photography. In 2004 Pete Carter and Bill Liebman were part of the
expedition as well as some of the 2005 participants.
