Where I was this past weekend

Bob Zimmerman underground

Several readers have asked in the comments for a report on what I did this past weekend.

I went caving. The photo to the right, taken on a previous trip several years ago, will give you an idea. The cave is amazingly beautiful. The trip was to designed to give a bunch of people a chance to see it.

I won’t say much more than this, mostly because it is unwise to reveal too much about the caves one visits because this then attracts people to them who are often either inexperienced (and thus a risk to themselves) or untrustworthy in terms of protecting the cave’s beauty. I am totally willing and open to bring anyone who wants to go to the caves I visit, but a newbie should go the first time with someone experienced, for the reasons already outlined.

Caving today

Though I have scheduled some posts to go up later today, I will not be able to do any live posting until late tonight, as I am participating in a cave conservation project for the day. We are doing a damage inventory of the formations in a cave in southern Arizona so we will know when any new damage or vandalism occurs.

Rappelling in the Grand Canyon

This past weekend I was completely out of touch with the rest of the world as I led a group of eight cavers hunting for new caves within the Grand Canyon. This was the fourth trip we’ve done to this part of the canyon, and on previous trips we were either mapping known caves, or scouting with binoculars the cliffs on the mesa’s walls, looking for potential openings. This trip we focused on rappelling down to the most likely candidate openings.

Overall we checked about a dozen potential caves, all of which turned out to be dead ends, mere alcoves. Oh well. Though this might sound disappointing, when you have to rappel off a cliff in the Grand Canyon, dropping out into nothing at heights ranging from 100 to 200 feet, who can complain? The image on the right, taken by Jeff Watkins, shows me (in the orange shirt) in the midst of one of these journeys. I am rappelling about 160 feet down to the top of the alluvial fill that you can see on the left that slopes down another few hundred feet to the canyon floor. In this image I am about a third of the way down, and am about to reach the spot where I will be hanging completely free of the wall.

Yowza! Though you can’t see it in this picture, behind me and opposite the cliff face the canyon extends out several miles to its opposite rim, with the Inner Gorge of the Colorado River cutting across in between. Once I reached the bottom I then rearranged my gear, using it to climb the rope back up 160 feet.

Nor was I the only one to do this. During the weekend we each got to do at least one rappel, each of which was as stunning and as breath-taking in its own right.

To say the experience was exhilarating is for sure a significant understatement. I used to do rappels this deep routinely when I was caving back east, but then the drop was underground, in the dark, with cave walls relatively nearby. Though that had a majesty of its own, doing this in the outdoors, in the Grand Canyon, is a far different thing.

How I spent the past two days

Black Canyon

I must apologize for the lack of posting the past two days. Diane and I have been up in northern Arizona staying at a friend’s cabin, hiking each day. The picture on the right shows Diane (right) and Jan Jantzer, whose house we have been staying, on today’s hike in Black Canyon, a canyon near Heber that is known by locals but is off the radar for most everyone else. Quite beautiful, especially because the recent rain has brought out the wildflowers. In addition, a forest fire about a dozen years ago cleared everything out, leaving behind a scattering of blackened tree trunks, many fallen logs, and open ground on which new growth has blossomed.

The canyon is also different in that it is wide and open, with sloping grassy walls interspersed with rocky cliffs. Most canyon hikes aim for high vertical walls and sculptured rock. Black Canyon instead was focused on the vegetation. As I said, very beautiful, and another example of why I left the crowded eastern United States for lovely Arizona.

I must add that the general news this week is so insane and filled with hatred that I needed a break.

Normal posting shall resume momentarily.

Perseid meteor shower this weekend

The annual Perseid meteor shower upcoming on August 12 is expected to be especially good this year because there will be no moon in the sky.

The Perseid meteors seem to come from a single point, the `radiant’, situated in the constellation Perseus, giving the shower its name. This is however just an effect of perspective, as the meteors move parallel to each other, much like drivers see when driving in heavy rain.

The radiant will be visible from around 10pm and at this time there will be the highest chance of seeing `Earth grazing meteors’. These are meteors that skim the Earth’s atmosphere and so have long, blazing tails.

Observers can expect to see a few tens of meteors per hour, or one every few minutes, once darkness has fallen on 12 August. The number of meteors will peak in the early hours of 13 August, when up to around seventy each hour should be visible.

It is worth it to find a nice dark place and stay up all night at least once in your life to watch this shower. Get a nice camp chair that allows you to lie back, make sure you are dressed comfortably, and sit back and enjoy.

Back from the hunt

I got back from my javelina hunt earlier today, and am only now getting down to some business.

Sadly, we didn’t bag anything. In fact, based on the lack of gunfire for miles around, I suspect not many others did as well. It seemed the area we were hunting might have become a bit popular in the last two years, and the javelinas have moved on, or gotten smarter about hiding. No matter. I don’t give up easy. We shall try again next year, probably in a different more remote location.

Even so, the weekend was quite pleasant. Got to spend my time wandering about in some beautiful country. The image on the right shows my hunting partner (and mentor) Gary looking across one wash.

Off hunting javelinas again

A javelina

Posting on Friday and over this weekend will be nil, as I am leaving tonight, Thursday, and will be in the back country with no phone or internet service on my second javelina hunt. If we bag something early we will be back early, but that can hardly be guaranteed.

For a description of my javelina hunt last February, go here.

Note that there will be an evening pause on Friday night, regardless.

Update: Due to technical issues, I am instead heading out tomorrow afternoon, so posting will resume for the morning hours.

On the road

Posting today has been lacking because Diane and I have been in the air, flying to the Bahamas where I will be giving a lecture tomorrow on space exploration at Lyford Cay Resort. We will be returning on Monday. I should get some posting over the weekend, but only in the evening after enjoying the day.

Posted from Nassau, the Bahamas.

Off to Israel + new op-ed!

My April travels continue. It has been too long since I traveled to Israel to visit family, so today I am heading out for the long flight, arriving tomorrow afternoon. I will be there until April 20. I expect I will be able to post, as I have in the past, though my commentary will likely be reduced somewhat.

Note that I will have a new op-ed published sometime this week at The Federalist entitled “What Trump’s space policy should really do.” I am positive that my conclusions will not be what most people expect. The op-ed was inspired by this comment by Edward Thelen, part of comments in connection with this Zimmerman/Batchelor podcast, where I talked about space exploration in the context of the American settlement of the west.

The comparison with the American west is appropriate. There have been other expansions throughout the world, too. In the 19th century, the US was not the only country that had a frontier. We have several examples of expansion from which to learn, but the frontiers in the Americas were clearly the largest, complete with immigration from the Old World straight to the frontier.

An example of a lesson — beyond Robert’s example of the Homesteading Act — is the need for better communication between the US east coast and California. Messages and people needed to move across the continent in far less time and in a safer manner than those that were available in 1860, so government funded a transcontinental railroad, a line longer than had ever been built or operated before. Earthbound or space-born governments may also have needs for similar large projects. Although the needs of We the People has been shown to be best met through private-ownership of free-market capitalist commerce, there will be times when government should also fund projects that solve its needs.

Edward was suggesting that the focus of the federal government — and Trump’s space policy — should be building an infrastructure that will make it easier for private companies and individuals to work in space. My initial response had agreed with him:

What NASA should do is build the kind of infrastructure that private enterprise needs to explore the Moon, the asteroids, and Mars. Build a communications network. Put communications satellites behind the Moon. Set up radiation monitors that private tourists trips will need to monitor solar and cosmic radiation. And even here, the model should be that used in the west with the transcontinental railroad, where the government hired private companies to do the work for it.

I need to think about this more. This needs to be written up properly.

In thinking about it, however, I completely rejected my initial response, and Edward’s suggestion. The infrastructure that the federal government needs to build in space has nothing to do with physical objects. This is the mistake everyone has been making for decades. In my op-ed I argue for something else entirely, and I hope the Trump administration is listening.

Stay tuned. When the Federalist op-ed gets posted I will post the url here immediately.

Hunting Javelinas

A javelina

This past weekend I participated on my third hunt, the second in which I was carrying my own weapon with the possibility of making my own kill. (For my first hunting experience I only came along as an observer.) The goal was to find and shoot a javelina, a boarlike wild animal whose range covers the southwestern United States down into Central America.

The hunt itself was what Arizona Game and Fish calls a HAM hunt, specifically limited to the use of handguns, archery, or muzzleloaders. This means that the only long gun you can use must be loaded through the muzzle one shot at a time, use black powder, and function somewhat like an old-fashioned musket. My weapon of choice was the 1911 pistol I use for bullseye competition, with a red dot scope, a customized left-handed grip, a carefully adjusted trigger, and in general carefully adjusted to be as accurate as possible. With this gun, shooting 45 caliber ammo, I can hit the black bullseye 50 yards away shooting one-armed about 70% of the time. At shorter distances, using two hands, I can easily group my shots in a space less than a few inches across. (Such accuracy on my part is actually not very impressive. Among bullseye shooters I am about average. The public’s general belief that pistols are not accurate beyond 20 feet is simply wrong. Practice, make sure your gun functions as it should, and you will reliably be able to hit your target at 50 yards.)

Since I really have no knowledge about hunting, I wouldn’t have dreamed of doing this without some help. My mentor this weekend was a local friend, Gary Kessinger, who has been hunting for decades, has a number of record kills, and routinely comes home successfully from his hunts. When I mentioned to Gary my desire to learn more about hunting and see how it is done, he gladly offered to guide me through the process. He hadn’t hunted javelinas much in the past few years, but decided to get his own license or tag so that he could shoot one himself.

As I told Gary on Saturday morning, I am essentially a babe in the woods, and would do whatever he suggested. My attitude was that I was the equivalent of a 10-year-old on his first hunt. Anything I accomplished well would be a success, even if it was merely learning how to spot javelinas on a distant hillside using binoculars.

The Grand Canyon

Park Service warning sign

When I posted here on Behind the Black that Diane and I were on our way to the Grand Canyon for our annual hike to the bottom, one of my readers, Keith Douglas, commented that he and his family would be there about the same time. In trying unsuccessfully to meet up, at one point Keith mentioned that his two kids, aged 24 and 23, were proposing they hike into the canyon. Keith emailed me to ask, “From what I read, hiking into the canyon and out is not recommended for a one day activity. What about halfway and back up? Can that be done in an afternoon? It seems pretty hot.” I responded,

Though one can hike down and up in one day, this is not recommended for most. Usually you need to be in very good condition and young. It also helps if you are a long distance runner. Hiking down to Indian Gardens [about two thirds of the way down] can be done as a day trip, but if you don’t hike a lot it will be an intense and long experience. Also, having the right pack and gear is essential! People who go carrying a one liter bottle of water and no hat are guaranteed to suffer.

I didn’t tell them they couldn’t do it, or that they shouldn’t, or that it wasn’t possible. I simply outlined some of the basics for doing it, and let them decide what to do.

Keith answered, with humor, “Thanks for helping me talk my kids out of a hike down.” He later added, “I read a hiking guide on the nps website. It seems to be designed to discourage canyon hiking rather than prepare novice hikers.”

In one sentence Keith encapsulated the problem with almost all of the advice the Park Service gives about the Grand Canyon.

Back to the Grand Canyon

Hiking in the Grand Canyon

Diane and I are about to leave for our annual hike to the bottom of the Grand Canyon. Though I might be able to post during the drive north today and from the hotel on the rim tonight, from Tuesday until Thursday I will be out of touch with the world of computers, a welcome break that I do need periodically.

Unlike previous trips, this time we are going with a bunch of friends. Last year I obtained a reservation for a 10-person cabin at Phantom Ranch in the Canyon so that we could all be together. Should be a lot of fun!
