A Better-Than-Expected Adventure

With our very warm March, we spent more time outdoors than usual, and one Sunday we decided to take a hike to check out a cave I had the coordinates to. I didn't have much more information than the coordinates, so we didn't know what to expect. We packed up and enjoyed the hike, seeing a few splashes of color as wildflowers like Indian paintbrush (above) and milkvetch (below) bloomed.


This juniper on the top of a cliff looked like a bonsai tree.

It took us about 45 minutes to find the cave. I rigged a rope to check out the entrance and found this western fence lizard hanging out on a midden part way down.

I had managed to forget a descent device (never mind that I have seven), so I rappelled on a munter. (It's great to know different techniques--if you'd like to learn more, check out this upcoming cave rescue training.) Then I climbed out and lowered my husband and Desert Boy. Desert Girl didn't want to be lowered, and I wanted to move the rope to an easier spot to get out of the cave, so we went in from this side, where we could see the dark mouth of the cave beckoning.

We only found one historic signature in the cave, Cliff Bellander on June 25, 1955.

The entrance descended steeply over boulders and cobbles.

Before long we saw old, weathered formations. The floor was primarily a packrat midden.

The cave kept descending fast, and I was glad I had my 20 feet of webbing to help belay the kids down the steep sections.

Most of the cave was very dry, but we did find this wet formation with very pretty decorations.

The cave wasn't large, but it was certainly larger than we were expecting. And more beautiful too. It's such a treat when things turn out that way! Then it was time to head out. Desert Boy scrambled out with the help of the rope before I even finished taking photos. Desert Girl tried, but needs a little more strength.

She was happy to be hauled out.

I wanted to get a family photo, but those seem to be hard to get when we all look happy.

We knew the truck wasn't far, and the kids wanted to get to the snacks. So they took off. I was impressed with how Desert Girl ran through the bushes, jumping over small obstacles.

I was a lot slower, pausing to take photos, like this bitterbrush seed.
It was a fun adventure and a good day.

Lint Camp 2015

 Lehman Cave at Great Basin National Park was the place to be for a lint and restoration camp in February and March.

What is lint?

Lint includes the tiny pieces of clothing (think dryer lint) that come off as we walk around. In a cave, air currents help them float around until they settle on cave formations, where they may change the way the speleothems form or provide an unnatural food source. Because caves are such sensitive environments, often with few changes such as sunlight and darkness, temperature swings, or flooding (at least in many caves in the arid Great Basin), they need a little help. They may need a lot of help if almost 30,000 people a year go through them, like Lehman Cave. If 30,000 people went through your house, it might need a little cleaning, too. (Mine needs a lot of cleaning with a lot fewer people than that!)

I took the kids to participate for a day. Desert Girl helped pick up pieces of litter with some tweezers. The tweezers made it a fun task.

A lot of people came for the February lint camp. We quickly became friends.

My friend Deanna came from Ely with her daughter, which made Desert Girl very happy.

But even with friends, the kids eventually tired of cleaning. They took a movie break. The cave proved to be an excellent theater.

Meanwhile, the volunteers were busy dusting stalactites and stalagmites, picking hairballs out of popcorn, and removing old trail debris to uncover natural cave floors. The back of the pickup truck started filling up.

So why would people volunteer their time to clean the cave? One reason is they get to visit parts of the cave that are usually off-limits, like the Talus Room. Here the special tour traverses the Sunken Garden, bypassing the pools of water.

We even found a pseudoscorpion, which is rare in this part of the cave.

Before long we were in the immense Talus Room. It is so different from the rest of Lehman Cave, cavernous and almost barren, with very few formations. Huge boulders litter the floor, giving testimony that this isn't one of the most stable parts of the cave.

Some beautiful formations do decorate the ends of the room and also this huge wall, called the Rainbow Wall.

On another slab, the cave has been turned into a bulletin board with signatures from 1885.
 Everyone enjoyed seeing the Talus Room.

Then it was back to work. Here are some rimstone dams that I was cleaning. Dirt had obscured many of the crenulations.

Another part of lint camp involved checking all the lights for algae growth, and upon finding some, spraying it with a bleach solution. The algae is not natural to the cave environment and also provides an unnatural food source.

 Lint camp has an interesting effect on people. Many come and are surprised by how much they like it. They find a zen in concentrating on just one area and making it look better. They start feeling like that little part of the cave is theirs. They can't wait to come back and make it look even better. They even say that they don't want anyone else to touch their spot--it's theirs and they have dreams about it.

So who knew? Lint camp is so much more than cleaning. It's about finding peace, making new friends, discovering parts of the cave that haven't seen the light for decades, and feeling that you're making a difference.
Thanks to everyone who participated in lint camp!

Oak City Cave

 A few weeks ago I took the kids to a cave I've been meaning to go to for many years: Oak City Cave. The entrance is a little crawlway. It's also known as a rattlesnake den, so I was glad that it was pretty late in the season and we didn't see any snakes.

We did see lots of pillbugs. I couldn't believe how many were in the entrance!

There were also lots of cobwebs.

And, unfortunately, lots of graffiti. I don't think some people realize how fragile cave environments are. The cave walls don't have the sun and wind like outside rocks, so it takes so very long for anything to wear away. And it often takes so long for a cave and cave formations to form in the first place.

Not far from the entrance was a six-foot drop I was expecting. It was something too hard for the kids to negotiate by themselves, so I made them hasty harnesses out of webbing and gave them a belay. Desert Girl was not at all sure about going down the big hole, but did fine.

At the bottom we were rewarded with some cave pretties.

The cave was larger than I expected. We didn't even have time to see it all before we were due out. Passages went in several directions, and even though they weren't long, we wanted to explore them thoroughly. I was very glad to have my kneepads.

We found another small pit, but it was easier to negotiate. I was starting to get quite warm by this point. I didn't have a thermometer, but guessed that the cave temperature was in the mid to upper 50s.

The kids found a cave cricket. They are becoming well-trained cave biologists!

When we came out of the cave, our nearby surface contact greeted us with bottles of water. That sure was welcome! Then it was time to call another surface contact. It's always good to let people know where you're going! It was a fun cave. I just wish that people who went into it treated it a little better.

Small Party Cave Rescue Class 2014

As a precursor to the upcoming epic Zion adventure post, I thought I better do this post.
 At the end of September I spent a long weekend in Garden City, Utah to help teach a Small Party Assisted Rescue (SPAR) class, sponsored by the National Cave Rescue Commission (NCRC). My friend Andy had asked if I would be a part of it, and since I enjoyed the previous one we had taught together so much, I said yes. Andy had found a huge vacation cabin that slept 26, so we had 20 students, 5 instructors, and 1 very awesome Bonny who did everything under the sun (or clouds) to keep us going.

It turned out the cabin had some great rigging opportunities, which we took advantage of for the Thursday night check-ins and Friday exercises.


Friday we also had a half-day of classroom activities, including learning about pre-planning, what to take in your cave pack, using your vehicle as your mini rescue cache (even if it's a horizontal cave, you can keep some vertical gear in your car just in case), hypothermia, improvised splinting (see below), suspension trauma, and a review of haul systems.

Then the afternoon was time to get on rope. The students rotated through different stations, such as the diminishing loop counterbalance (a super small party rescue technique).

 We also taught how to get a person stuck on rope down to the ground quickly by converting to a lower. Of course, the best way to make this quick is to rig a contingency anchor (for example a munter tied off), so if someone gets stuck, it takes about five seconds to start lowering them.

Students (and instructors) loved doing the rebelay course, a rope course that included switching to different ropes, a deviation, and a J-hang. You really learn to tune your system so you don't expend too much energy.

In the evening we enjoyed a good rigging/bad rigging lecture. You need to know your gear. And test your anchors. Every time.

The next day we headed to a nearby cave under the threat of massive rains. The rains did come, but we went anyway. It's not always good weather for rescues, after all. The cave was ten minutes away by car and then a ten minute hike. The 30-foot pit provided us a variety of scenarios, expanding on what we had taught the day before, like how to use a diminishing loop counterbalance when you have to dangle it over the edge. We also did some in-cave movement and traveling hauls, where the haul system moves up the rope with the patient instead of being at the top (or bottom).

Here's the rigging for a contingency anchor, along with a canyoneer rappelling down on his piranha. We had a bunch of canyoneers in the class, and it was fun trading techniques.

By lunchtime everyone was soaked, so we headed back to the cabin to practice some other techniques, like how to get a patient through a rebelay (below).
 That evening we had a presentation from a local caver who had shattered his scapula (shoulder blade) in a caving accident this past summer and how he had self-rescued out of the cave. It was a great story and a good lesson for us all.

Then on Sunday it was time for the mock scenarios. We drove in the rain up to Paris Ice Cave, a place we had visited previously. This time I saw it with very different eyes as we set up three scenarios for the students. They did great.

It was a super weekend despite the unfavorable weather, and I had a super time. I learned a few new things, which I greatly value, and met and got to know some folks a lot better. In fact, I met up with one of the students a couple weeks later for our epic Zion adventure. 

If you go caving and have a chance to take a cave rescue class, by all means take it! I have become a much safer caver knowing what would happen if I get hurt deep in a cave--or even not so far into a cave. You can find a list of upcoming classes on the NCRC website.

Cave safely and softly!

National Cave Rescue Commission Camp Goldenbell, Colorado

If you've been reading this blog for any length of time, you know I like caves. Early on in my caving career, I became friends with some cavers who also were into cave rescue. They got me interested, and over the years I took enough classes (four eight-day classes to be exact) plus helped with many smaller cave rescue classes (also known as Orientation to Cave Rescue (OCR) classes) that I was permitted to take the test to become an instructor. Over the years I've instructed a variety of classes, and this year I was able to help instruct the Level 3 class at the national seminar for the National Cave Rescue Commission (NCRC). It was held in May at Camp Goldenbell, Colorado. (I think I mentioned before I was a little behind on some posting!)

It was my first time to help with the Level 3 class, which is more technical than the previous classes. Students had to pass various technical skills in order to be able to get into the class, as well as have had the Level 1 and Level 2 classes within a certain time period. We had a full class with a waiting list, and it was a great class! To see just how well they knew their stuff, one morning they were challenged to some knot tying. But not regular knot tying. This was with your eyes closed, or with just one hand, or behind your back (photo above), or with oven mitts, or with a partner. It was fun for everyone.

Soon it was time to head out to the cliffs to evaluate their skills and ability to work together. We did some basic anchors and hauls and lowers.

They did very well with all of that, so then we gave them more challenging problems. The colorful accessory cord and rope make it easier to tell what's going on in the photo below.

Everyone should be a pretend patient at some point, as it's a very strange feeling to be dangling on a rope, swinging in a basket.

The students were doing so well that we decided they needed one final challenge: to go down a boulder, through a hole in it, and up the other side. This would require the whole class (which had previously been split up) and be a communications challenge. The down and through part went smoothly.

 The up part was the most complicated. Here's a view of the litter still horizontal.

Then it was shifted to vertical. Then there were problems with some torque issues on one high anchor and some pre-tensioned (or I guess in this case, post-tensioned) backties were added at the last minute. And they succeeded in getting the patient to the top of the boulder again.

Since it was a cave rescue class, we wanted to spend as much time in caves as possible. The caves we had to work with didn't have large work spaces, so we split the class into three smaller groups and they had a variety of tasks to do, such as counterbalances, traveling hauls, and tensioned traverses. (If you want to know more about these things, in addition to taking NCRC classes, the books On Rope and Alpine Caving Techniques are very helpful). My camera didn't do great in the cave, so I didn't get as many photos of our cave days.

I did get a lot of photos on our highline day, when we sent a rescuer out to the middle of a gorge, then down to the river to pick up a patient, and back to the shore using a Norwegian Reeve.
 Can you see the rescuer?
After that very gear-intensive and long exercise, they were challenged to get me (wearing my harness) from one side of the river to the other using only two ropes and six carabiners. They did it in less than half an hour. Sometimes less gear makes things go a lot faster!

Then came the mock-mock day. We used part of Cave of the Winds for the exercise. All four classes (Levels 1, 2, 3, and TOFE) came together, and then were split into three mixed groups. I led one of the groups with a cadre of excellent instructors to one part of the cave, where we put on four mini-scenarios so everyone would learn more about how to launch a cave rescue and how to participate in various roles, such as communications (using old army phones, as seen below).

Finally came the culmination of the class: the mock rescue. This is an all-day event that the students solve with minimal instructor interaction. My role was to be entrance control for instructors going in and out of one of the caves used, plus to check the rigging used to take the patient from the cave entrance to the canyon bottom many hundred of feet below. It was a great spot to see people as they came to the cave.

The rigging was very nice, and after many hours, the patient was brought out of the cave and then taken down to the canyon bottom. The only problem was that a for real big storm came in, and the canyon is subject to flooding. So before everything could be derigged, we got everyone out of there as fast as we could. Some went up to the parking lot where we had started, others went down out of the canyon on a faster trail. But then they closed the roads for hours, and the two groups were stranded, bringing some real logistical challenges. The Colorado cavers did a super job of sorting it all out, and everyone got back to camp safely in the wee hours.

It was a super experience checking out the Colorado cliffs and caves. The students I talked to got a lot out of the class. Next year the national NCRC class will be held in Park City, KY from July 24-Aug 1. Other NCRC classes will be held throughout the year in various locales. If you like caving, I definitely recommend a cave rescue class, as it will make you cave a little differently--hopefully safer!
