This February, guidebook author Janet Chapple was pleased to celebrate her birthday with a banquet at the Bellevue Club, in Oakland, California. Family and friends traveled from far and wide to join the party. Four of Janet’s friends played a Haydn string quartet for us.

One guest, a violinist, revealed in a short speech that he learned on a trip to Yellowstone how highly regarded the book by his musician friend really is. A park ranger told him that Yellowstone Treasures was the best guidebook to the park he’d ever seen. He realized then that the book was by the cellist he enjoys playing chamber music with.

After dining on sea bass, salmon, or filet mignon, the approximately 40 guests, myself included, got to try this lovely layer cake.

Art for February birthdays

Moran painting of Grand Canyon of the Yellowstone River

Snapshot of Grand Canyon of the Yellowstone, Wyoming, 1906, painted by Thomas Moran.

I just took this photo in the De Young Museum, Golden Gate Park, San Francisco. (Apologies for the fuzzy quality of photos taken with my iPad.)

It’s appropriate to post this, because painter Thomas Moran’s birthday is coming up. He was born in England on February 12, 1837. Many people think that Artist Point on the canyon rim was the place Moran sat to create his famous paintings, but that was at another spot, now called Moran Point. See this page in the Yellowstone Online Tour to straighten out that fact.

And why do I find myself in San Francisco today? I traveled to the Bay Area to celebrate a few family birthdays, guidebook author Janet Chapple’s among them. Happy February Birthdays!

Watching Yellowstone wolves

Just so my readers don’t miss it, I am passing on a link to a lovely story about the difference seeing wild wolves can make in people’s lives. The story appeared yesterday on the National Parks Traveler site.

Yellowstone Geyser Eruptions: How Do They Work?

Knowing that lots of people would like to learn how geysers work, I’ll take a stab at explaining the requirements and the mechanism as simply as possible.

What is required to create a geyser and what’s happening when it erupts? All geysers have four requirements: water, heat, the right kind of rock, and a system of conduits and reservoirs (plumbing) that includes one or more constrictions to keep water and steam from flowing freely to the surface. The water pooled above such constrictions acts like a lid to maintain pressure on water below. Such constrictions differentiate geysers from the much more common hot springs. Although no one has yet been able to see exactly what this plumbing looks like, it must be something like this diagramGeyser Mechanism Figure drawn by my husband Bruno Giletti for Yellowstone Treasures. The countless different shapes the underground plumbing may take must account for the great variety in the patterns and timing of Yellowstone’s geyser eruptions—what I call their personalities.

Whether the water comes from the vent in the distinctive cone of Beehive Geyser2004_BeehiveG. or from the beautiful geyserite-ringed pool of Great Fountain Geyser, 2008_GreatFtnG the mechanism is the same.

Deep below the geyser’s vent or pool seen at the surface is a kind of rock that is rich in silica. In Yellowstone this rock, called rhyolite, was deposited in huge amounts when the caldera erupted. Silica is the primary element in the hydrous silicon dioxide (technical name for geyserite) that is deposited both along the conduits of the geyser’s water passages and all around its surface vent.

Also deep below a geyser are (1) a source of heat—in Yellowstone it is the still extremely hot volcanic rocks more than two miles below the surface—and (2) the water that has seeped into the earth from snowmelt and rain (meteoric water), and voila!—the geyser erupts.

As water gradually fills the reservoirs and is heated from below, it becomes superheated and forms steam bubbles, and the water pressure increases. Eventually, the steam pushes some water out of the vent, and steam—which requires something like a thousand times more space than water—is also released. When the pressure is thus sufficiently reduced, the steam in the conduit can blow the water column out of the vent. In many geysers, when the water supply is exhausted, the remaining steam continues for the steam phase of the eruption.

I have gleaned some ideas for this post from the sidebar my husband Bruno Giletti, a geochemist, wrote in Yellowstone Treasures (pages 88 and 89) and from T. Scott Bryan, a former ranger and also a geologist and author of books about geysers, including his Geysers: What They Are and How They Work. But as early as the mid 19th century, German scientist Eberhard von Bunsen and others already had it pretty well figured out. You can find out more about the study of the geyser mechanisms here in my September 2013 post.

A quick heads-up on Yellowstone’s wolves

Exactly twenty years after gray wolves were reintroduced to Yellowstone Park, Kathie Lynch has given us a wonderful summary of their present very healthy state in the park. This is spite of the unfortunate killing of several collared wolves, at least three of them alphas, in the three hunting seasons since they were removed from the Endangered Species list in Montana, Idaho, and (until September 2014) in Wyoming.

Time lines

Jack Baronett wooden bridge

“Yellowstone Jack” Baronett’s bridge over the Yellowstone River


Inside the guidebook Janet shares many anecdotes about the human history of the Yellowstone area, from prospector Jack Baronett who built a wooden toll bridge in 1871 to tourist Hazel Decker who camped in her car for 52 days to observe Steamboat Geyser. In the road logs she discusses the evidence of prehistoric peoples and the recent discoveries scientists have made at the bottom of Yellowstone Lake using a submersible robot. She compiled a time line of many of the important events in the Yellowstone area and the world in a chapter of Yellowstone Treasures called “Chronology: Yellowstone Since 1800,” which takes readers from the Lewis and Clark expedition up to the present day.

But when she and I were creating the first edition of the book in 2001 it became necessary to cut pages from the manuscript and restrict the time line to the most recent couple of hundred years of human history, even though the geological history of the region goes way back before that. Her Geological Time Line, which you can read right here on this website, extends all the way from Earth’s formation 4.6 billion years ago, through the time the Absaroka Range volcanoes formed 53 to 44 million years ago, to the time 12,000 years ago when glaciers last covered Yellowstone. This last episode was the Pinedale Glaciation, evident throughout the lower Lamar Canyon.

Thanks for spending the time with us,
Editor Beth

Navigating around yellowstonetreasures.com

You might like to know how to make the most of your visits to yellowstonetreasures.com, so I’ve decided to provide you with a sort of navigational post.

First, on the home page, by clicking on the white bar below the row of pictures at the top, you can move across the page and find seven different pictures. Then, clicking on any one of the pictures or on the descriptions below them takes you to a page related in one way or another to the home page picture. For instance, clicking on the elk gives you a detailed article about the resident elk herd at Mammoth Hot Springs.

Also on the home page, moving your cursor across the top yellow strip to click on Author Blog, you will find the page with our current posts (most written by Author Janet, but some by Editor and Publisher Beth). At the top right of this page is a search box where you can enter a word and come up with all the blog posts and pages (or nuggets) covering that subject here since May of 2009. I just put in the word “bears” and found 18 posts and 8 nuggets discussing grizzlies and black bears. A search for “geysers” brought up 28 posts and 24 nuggets.

On every single page of the website, you can find things another way by scrolling down and entering your search word in the Search box at the bottom right.

One further search aid you might find helpful while you are on either the main Nuggets or Author Blog pages, is the Categories and Archives boxes at the lower right.

Happy navigating in 2015!
