Because I often write fiction set in Yellowstone National Park, it should be no surprise that I follow the social media streams from the park. Of course, it’s also a favorite vacation spot, although my aversion to cold keeps me away at this time of year. A few days ago, the Yellowstone Facebook page posted a lovely picture that called to mind a scene from one of my stories and also introduced me to an interesting new term.
Bobby socks trees at Mammoth Hot Springs, Yellowstone National Park
The picture showed a scattering of standing dead pines covered in morning frost and in the background just a faint hint of a dark forest tree line through a thick fog. According to the caption, the photo was taken at the Lower Geyser Basin; the location around thermal features explains the dead trees as they don’t tend to thrive in the hot water, steam, and excessive minerals typical in such locales.
These dead lodgepole pines are known as bobby socks trees because of their white bottoms, which is caused when the trees soak up the mineral-rich water of the thermal area. After the water evaporates, they appear to be wearing white ankle socks because of the minerals left behind, and thus the name. With all my many trips to Yellowstone over the years, it seems like I would have heard this term before, although if I did, it certainly didn’t stick.
I like the term bobby socks tree because it’s so wonderfully evocative: The name describes the thing. I tried to discover how common or scientific this term is through a variety of online searches, and although there isn’t a wealth of source material, it is in fairly common use, even by the National Park Service. (Along the way, I also got to learn a bit about the history of bobby socks themselves, and why not?) It just makes me wonder why more scientific terminology doesn’t follow such obvious or descriptive naming conventions—I’m sure we’d all find it much easier to remember our science lessons if so.
You can see the picture that sparked this musing here. Although I might not have known the term, I find I’ve been taking my own pictures of bobby socks trees for quite a while. They frequently provide an interesting foreground for some larger and more colorful background, such as the Mammoth Hot Springs area of the park, which is where my photos that accompany this post were taken.

Yellowstone contains a wealth of evocative names. Dragon’s Mouth Spring. Frying Pan Spring. Dot Island. Fairy Falls. Castle Geyser. Even Old Faithful, for goodness’s sake. They’re names that describe the feature or perhaps have some significance in its history. And they’re names that call to mind fantastic stories, which goes a ways to explain why I’ve spent so much time writing about this place.
I learned a new Yellowstone term this morning, also from the park’s social media. From a post called “Unexplained and Unreported Phenomenon in Yellowstone” on the park’s In the Shadow of the Arch blog, I learned about “lake music.” Apparently, this is a phenomenon where people hear a buzzing sound above Yellowstone Lake and Shoshone Lake, and it was reported as far back as the 1880s. Something else I’d never heard of—or heard!
I’ll be listening for lake music on my next Yellowstone trip, and I imagine this phenomenon will have to end up featuring in a story at some point. I haven’t decided about Bigfoot yet.
