Aerial Geology in the New York Times!


Aerial Geology at Phoenix Book in Burlington, VT

In the past two months, I’ve found Aerial Geology in bookstores from Bozeman, Montana to Moab, Utah to Burlington, Vermont. The team at Timber Press has done an incredible job getting it out into the world! This weekend, Aerial Geology is featured in the New York Times Book Review/ Holiday Gift Guide!

“What better way to introduce geology to any reluctant science student than a book full of breathtaking “who knew?” moments. Luckily, the writer and mountaineer (and, appropriately enough, resident of Big Sky, Mont.) Mary Caperton Morton knows. Take in the natural splendors of the view from an airplane window: This generously photographed volume even offers flight patterns that will reveal our earthly treasures. – Dominique Browning, NYT

I don’t really comprehend how somebody could be a “reluctant” geologist… the Earth is the coolest planet in the whole Universe! But I do think Aerial Geology makes the perfect gift for just about everybody on your Christmas list! I’ve had a lot of great feedback from kids to grandparents. Pick up a copy at your local bookstore (they probably have it!) or on Amazon (it’s a #1 Best Seller!) or get it from the source… signed copies are $27 plus $5 shipping direct from me.

Aerial Geology: San Rafael Reef


In geologic terms, the San Rafael Swell is an anticline: a fold in the Earth’s crust that looks like a dome in cross-section. The Swell formed between 60 and 40 million years ago, when the Rocky Mountains were rising to the east, both uplifted by the same forces deep in the Earth’s mantle. As the top and sides of the dome split and fractured, rainwater found its way into the cracks, eroding them deeper and forming a convoluted network of slot canyons that drain the Swell, some only a few feet wide but hundreds of feet deep.

The eastern side of the Swell, called the San Rafael Reef, is the most dramatically tilted and fractured part of the dome. Made up of steeply tilted layers of erosion-resistant white Navajo sandstone and red Wingate sandstone, these hard rocks have formed into upright fins, cliffs and deep canyons.


I’ve visited the San Rafael Swell a few times and have wriggled through its slot canyons and tested my navigating skills by hiking cross-country into its labyrinth of folds, but I hadn’t yet seen it from on high. And you all know how I love learning about the landscape from altitude! So Dan and I set our sights high: a nine pitch climb to the top of the San Rafael Reef up a route called Death By Chocolate.






Read more about the San Rafael Reef in my book Aerial Geology out now from Timber Press! I emerged from a few wifi-less days in the desert to great news: Aerial Geology is a #1 best seller on Amazon!

Aerial Geology: The Dragon’s Back


Northwest New Mexico is one of the driest places in the country – the region gets less than 12 inches of rain a year, most of it during the late summer monsoon season. But despite the aridity, this desert is shaped by water. During the Mesozoic Era, starting around 160 million years ago, what is now New Mexico was flooded by the Jurassic Ocean, a shallow inland sea that covered most of the Southwest United States. The Jurassic Ocean was very salty and rich in minerals that left behind extensive deposits of limestone and gypsum.


These layers of gypsum, a white crumbly rock, have eroded away to sculpt a formation known as the “Dragon’s Back”, a 2.5 mile-long ridge with a bulbous head and a tapering tail that, from the air, has the appearance of a great white serpent, standing out starkly against the red and orange landscape. Look closely and you may see tiny mountain bike riders or hikers making their way along the spine of the Dragon’s Back. The trail is not for the faint of heart: gypsum is a water-soluble mineral and eons of rare rains have melted a few sinkholes into the top of the ridge, some big enough to swallow a bike whole.


The top of the Dragon’s Back is wide enough to bike or hike across without much danger of falling off, but narrow enough in some sections to trigger vertigo. The east side of the ridge drops steeply down into a enormous bowl, carved out by erosion over the past 150 million years. This bowl is known in geologic terms as an anticline: a fold in the Earth’s crust that creates a convex dome. This anticline, however, is different. It’s no longer a dome – the middle layers have been scooped out by erosion – leaving behind a bowl with upswept sides. This feature is so unique that geology classes from the University of New Mexico in Albuquerque journey here each year on field trips to see it in person.

Dragons back

The name the Dragon’s Back is fitting, and not just for the formation’s distinctively reptilian shape. During the Mesozoic, when the layers that form the Dragon’s Back were laid down, dinosaurs dominated the land and the sea. New Mexico is home to some of the most productive dinosaur bone yards in the country, including in the Ojito Wilderness, just 10 miles south of the Dragon’s Back, where one of the longest dinosaurs found to date – the 110-foot long Seismosaurus – was uncovered in 1985. The long-necked, long-tailed Seismosaurus was a species of Sauropod, related to the more famous Apatosaurus and Brontosaurus. Other fossils are common in the area, including whole petrified trees.


Flight pattern: You may catch a glimpse of the Dragon’s Back flying into or out of Albuquerque, located 50 miles southeast of San Ysidro. From the air, the Dragon’s Back appears as a curving white ridge against a red background, just west of highway 550.

Aerial Geology: Alaska’s Malaspina Glacier

A river of ice the size of Rhode Island, spread out like pancake batter on a hot griddle

Glaciers are essentially rivers of ice but they can take many shapes depending on the underlying topography. The almost perfectly round Malaspina Glacier in southern Alaska is the largest piedmont glacier in the world – larger than the state of Rhode Island. Piedmont glaciers take shape when one or more glaciers spill out onto a relatively flat plain, where they spread laterally, like pancake batter on a grill.

The Malaspina Glacier covers more than 1,500 square miles and is fed by several glaciers, including the central Seward Glacier and the Agassiz Glacier, which descend from the Saint Elias Mountains onto the coastal plain between Icy Bay and Yakutat Bay. The edge of the piedmont glacier comes within a few miles of the Gulf of Alaska but terminal moraines – large deposits of rocks carried to the end of the glacier by moving ice – keep the Malaspina from reaching the water.

Yikes Stripes! Medial moraines created by rock and debris riding on top of the many glaciers that make up the Malaspina. Aerial photo by Bruce Molnia/ USGS.

From the air, wavy, circular and zig zag patterns can be seen across the top of the glacier. The brown lines against the white ice are moraines – glacial debris including rocks, soil and dust that get scraped up by the glacier as it moves and deposited on top of the ice, usually along the sides of the glacier. When two glaciers come together, these lines of debris merge to form a medial moraine closer to the center of the ice.

Glaciers that flow at steady rates tend to have relative straight moraines, while those that periodically surge due to increased melt or steep changes in topography develop wavy moraines as a result of folding, shearing and compression of the ice. The patterns of curves, zigzags and loops on Malaspina are the result of such surges and of many glaciers combining into one mass of ice on the flat plain.

Aerial Geology: Quebec’s Pingualuit Crater

A NASA satellite image of the Pingualuit Crater among other lakes in northern Quebec

Northern Quebec is laced with over half a million lakes, formed by water pooling on top of the ubiquitous bedrock of the Canadian Shield, the geologic core of North America. One of these lakes, however, stands out from all the rest by being perfectly round. Located on the Ungava Peninsula in northern Quebec, this circular lake sits inside the Pingualuit Crater, a scar left in the Earth’s crust by a meteorite impact 1.4 million years ago.

Pingualuit translates from the Inuit language as “place where the land rises.” From the ground, the crater does appear as nothing more than a sharp rise, with the rim of the crater looming 500 feet taller than the surrounding landscape. When the meteorite hit the hard rock of the Canadian Shield, it exploded, melting thousands of tons of rock and incinerating itself in the process. Today, few traces of the meteor have been detected near the impact zone. The force of the impact shattered and shocked the rocks that now make up the crater rim, causing them to expand out and up, forming a raised ring in an otherwise flat landscape.

You will likely only fly over the Pingualuit Crater on a chartered flight. This isolated place is over 60 miles from the closest settlement and difficult to reach except by air. Image by NASA/ Jesse Allen.

The scar the impact left behind is over 2 miles in diameter and 1,300 feet deep, and filled nearly to the brim, making this one of the deepest lakes in the world. The lake has no inlets or outlets, though it does host a population of arctic char fish that have evolved to be genetically unique due to their isolation from other char populations. All the water that has accumulated in the lake comes from rain, snow and snowmelt, making for exceptionally clear freshwater. Viewed from the air, the water appears bright electric blue due to its depth and purity.

The Pingualuit Crater has been known by the Inuit for thousands of years and is considered a sacred place of healing. The crater was put on the map by pilots during World War II, who used its perfectly round shape to navigate across the often confusing lake-covered landscape of northern Quebec. Today the crater is protected within the boundaries of Pingualuit National Park
