An Iconic Bit of the Calaveras Fault in Hollister is Gone (But it will be back)

Corner of Locust and Central Avenues in 2016 I go on field studies trips year after year, and my camera is always around my neck, to the amusement of my students. They sometimes wonder why I would take pictures of things I already have dozens of pictures already. Show More Summary

Why did the Road Cross the San Andreas Fault? 15 Years of Geologic Change (an Update)

2002 I've been leading geology field studies trips to lots of places in the American West for 29 years and started to take digital pictures in 2001. I sometimes struggle to find new things to photograph when I visit a place for the 29th time, but in some cases it is not a problem. Show More Summary

Aerial Geology: A High Altitude Tour of North America's Spectacular Volcanoes, Canyons, Glaciers, Lakes, Craters, and Peaks. A Book Review...

A most interesting book landed on my desk recently. Timber Press asked me if I was interested in reviewing Mary Caperton Morton's book Aerial Geology, A High Altitude Tour of North America's Spectacular Volcanoes, Canyons, Glaciers, Lakes, Craters, and Peaks. Show More Summary

A Landscape as Bizarre as They Come: The Volcanic Tableland of the Eastern Sierra Nevada

The Volcanic Tableland, with the White Mountains beyond. There is a bizarre landscape on the far side of the Sierra Nevada between Bishop and Mammoth Lakes. It's not one of stark beauty exactly, it's barren and covered by little more than sagebrush. Show More Summary

What? Why Would I Ever Want to Give Up my Parking Spot in Yosemite Valley?

"Why?", indeed. I have to admit that I get just a little tiny bit elitist at times, at least in my approach to visiting my favorite national park, Yosemite (program note: my "favorite national park" is likely to change on a nearly daily basis, depending on whichever one I happen to have visited most recently).

Looking Down on Yosemite: A Return to Taft Point

I don't know how it happened, but somehow 12 years slipped by since I last made the hike out to Taft Point above the floor of Yosemite Valley. It's not that tough of a hike, only 1.1 miles with just a bit of climbing on the way back....Show More Summary

Perhaps a Last Look at Some Yosemite High Country (for the Winter, Anyway)

"Half" Dome from Washburn Point I made the trek up the hill to see Yosemite last weekend, with a field trip on the valley floor on Saturday with my students, and a quieter tour in the high country with Mrs. Geotripper on Sunday. We headed up Glacier Point Road to gain a unique perspective on Yosemite Valley and the higher country above. Show More Summary

Finding Peace in the Nation's Most Crowded Park: A Walk Through Yosemite Valley

If you've read my previous couple of posts, you know I was in Yosemite Valley over the weekend. I was guiding my students on a field trip up the Merced River and into the park on Saturday, and I came back on Sunday seeking some better pictures of the recent rockfall at El Capitan.

El Capitan Rockfall: Alternate Views, and a Realization That This Wasn't the First TIme

El Capitan and the September rockfall from Taft Point on Oct. 29, 2017 Yosemite Valley changed geologically on September 27 and 28, and as I noted in my previous post, the valley will never look the same again. A series of rock falls...Show More Summary

You Can Never See This View Again. Ever.

The title isn't as ominous as it sounds, but it is true. This is the panorama seen from Tunnel View at the west end of Yosemite Valley, one of the most famous viewpoints in the world, in 2013. But the specific scene above can never be experienced by anyone ever again. Show More Summary

Trump Demonstrates the Need for the Antiquities Act: Fighting for the Bear's Ears and Grand Staircase-Escalante

It's not complicated. It's called the Antiquities Act, and the law has but four sections, and no subsections. You can read it in its entirety below. It lays out the process by which the president of the United States can establish aShow More Summary

Ghosts of the Empty Lands East of the Sierra Nevada: The Town of Bodie

The Matterhorn Crest of the Sierra Nevada from Bridgeport. Bodie is another twenty miles to the east. Central California is almost literally a "land flowing with milk and honey". The Great Valley (called by those who live elsewhere the...Show More Summary

How Does a Pristine Cavern Look? Black Chasm Provides a Clue

Some things can only be experienced once. The discovery of a new plant or animal that no one has ever seen, a new mineral, a new planet in space, to see a vista that no one has witnessed before. Exploration of new things is one of the great joys of being human. Show More Summary

Can't See the Forest for the Creek; Or is it the Other Way Around? California's Mega-droughts

The eastern Sierra Nevada is home to one of the strangest forests I know of. It's not the species of tree that is odd; they are mostly Ponderosa, a pretty but unremarkable tree which can also be found on the adjacent slopes. What's strange is that these trees are dead. Show More Summary

28th Anniversary of the Loma Prieta Earthquake - It Was a Warning That is Still Operative

What a different world... on Oct. 17, 1989, there were no smart phones, the internet barely existed, and we still depended on things like newspapers, television and radio to keep up with the world. Most of my current students had not yet been born, and that means that most of my students have never felt or experienced a major earthquake. Show More Summary

Feeling a Bit Sheepish: A Bit of Glacial Mutton in the Sierra Nevada

Pothole Dome in Tuolumne Meadows at Yosemite National Park Sometimes glacial terms represent some kind of logical relationship to reality. "Horns" that are sharp pointed glacial peaks, "cirques" that are circular-shaped glacial bowls,...Show More Summary

You Just Can't Take Sonora Pass for Granite: Travels Around the Sierra Nevada High Country

Sonora Pass in the Sierra Nevada is a sort of forgotten step-sister of the more famous Tioga Pass in Yosemite National Park. A paved road, State Highway 108, crosses the crest of the Sierra about forty miles north of Tioga, cresting out at 9,624 feet, but it sees far less traffic. Show More Summary

Fall Colors in the Eastern Sierra Nevada!

2 months agoAcademics / Geology : Geotripper

We've returned from a field studies expedition to the eastern Sierra Nevada, and I can report that fall has arrived! We've had a very warm summer, and the heat waves continued into September, but then we had a sudden cold snap, and even some snow. Show More Summary

Say Hello to California's New State Dinosaur: Augustynolophus morrisi

2 months agoAcademics / Geology : Geotripper

This one really got past me. I have to admit that the whole business of establishing a California State Dinosaur flew way under my radar. But it happened, Jerry Brown signed the bill, and Augustynolophus morrisi is our newest state emblem (along with our state fabric, denim). Show More Summary

Liveblogging the Deluge: The First Day of Fall and a River Finally Returns to Abnormal

2 months agoAcademics / Geology : Geotripper

I was mistaken. Nearly two months ago, I suggested in a post that the abnormally high flows on the Tuolumne River were finally subsiding, and that the great flood of 2017 might finally be ending. This happened because I strolled along...Show More Summary
