Pyroclastic Pixels Goes to Italy!

The village of Vernazza occupies rocky cliffs and ravines along the Ligurian Coast of Italy. 

We recently returned from a week in Italy; a refreshing change of pace, both scenically and climatically, from winter in the Utah desert! While we spent the majority of the trip enjoying the historic sights of Florence and Rome, just a handful of hours after touching down in Italy, we were aboard a high-speed train bound for the Cinque Terre, a rugged section of Ligurian Sea coastline where we spent the first several days of our trip hiking, exploring, and ingesting some of the best seafood of our lives. The Cinque Terre (“five lands”) consists of five small villages clinging to the rocky shore, surrounded by ancient stone terraces, vineyards, and olive groves, and crisscrossed by a network of hiking trails that, since 1999, have been part of the Cinque Terre National Park. A hot tourist spot in peak summer season, in March, with the temperatures still far too cold and the skies much too drizzly for a dip in the sea, the streets and trails were definitely still enjoying the relative calm of the off-season. On the stormiest day, we struggled to find an open restaurant or market to grab a bite to eat!

The five villages (from south to north: Riomaggiore, Manarola, Corniglia, Vernazza, and Monterosso al Mare) are spread out along a six mile stretch of shoreline. A regular train connects the five villages to one another and the larger cities of Liguria, making its way along the coast via a series of long, dark tunnels, only to pop out into the open briefly to stop at the station adjacent to each town. Coming from La Spezia (the closest major city to the Cinque Terre), we hopped off the train at Manarola, our home base for our all-too-short stay:

Like the other four towns, the colorful buildings of Manarola cling to the hillsides in impressive fashion. The terrain, while steep, is relatively easy to traverse thanks to the vast network of dry stone terraces, originally built centuries ago. Not only do the terraces help minimize erosion of the precipitous slopes, the treads provide flat surfaces on which grapes, olives, lemons, and other food products are grown. Most of the trails that wind through the Cinque Terre follow these historic terraces, providing an easy walking path, great views, and an up-close look at many of the vineyards which are still operated to this day.

Despite the convenience of the train, the most enjoyable way to travel between the towns is to walk. Hiking is one of the primary attractions here, and the five villages are connected by a famous 7-mile long coastal trail that follows the curves of the shoreline in dramatic fashion. So dramatic in fact, that many segments have been closed for years due to landslides that have made them dangerous and impassible. On day two, we struck out from Manarola to hike to the next village to the north: Corniglia. With the direct route along the coast closed indefinitely, we undertook a more circuitous route up through the vineyards and terraces to the village of Volastra, then back down a steep grade to Corniglia. The views of the Ligurian Sea from this trail were phenomenal, despite the occasional rain & thunder.

Agave and other plants cling to a rocky sea cliff

We were surprised at the how many different kinds of agave and cacti graced the slopes of the Cinque Terre. It was odd to see so many of the familiar “desert” plants from our Utah home in such a temperate climate! Here, several agave cling to a vertical cliff not far from our lodging in Manarola. 

After enjoying a picnic in Corniglia, we opted for a short rest and utilized the train to reach the next town of Vernazza. Vernazza was by far the busiest and most active town we visited; it was hard to imagine what the crowds would be like in the sweltering heat and humidity of summer. Interestingly, Cinque Terre, which attracts ~2.5 million visitors each year, faces many of the same challenges as Zion National Park in our own backyard: namely, lots of visitors and not a lot of room for them to spread out. The peak-season crowding has gotten bad enough that the Cinque Terre National Park, much like Zion, has begun exploring the use of reservation systems and other strategies to mitigate the crowds in peak season. Another parallel between Cinque Terre and Zion: deadly flash floods. In 2011, heavy rains swelled many of the streams that the villages are built along (or literally over in many places), killing several and burying the main streets of Vernazza and Monterosso in over a dozen feet of mud. While the towns have mostly recovered, the reality is that this will always be a very geologically active place. Nature doesn’t like near-vertical terrain.

The city of Levanto and surrounding hills

The town of Levanto, just north of the Cinque Terre and the start of our hike to Punta Mesco

On our final day, we left the Cinque Terre proper and headed to the small town of Levanto, just to the north. Our plan was to hike a lesser known section of the coastal trail that traverses a wide peninsula jutting out into the Ligurian Sea, and then back to the Cinque Terre and Monterosso via Punta Mesco. Oddly, we saw far more people along this stretch of trail than we seen the past few days in the Cinque Terre, including an excursion of an Italian hiking club numbering at least 100 people. After a few dreary days, we finally got to bask in the beautiful Mediterranean sun on this trek, and were rewarded near the end with exquisite views of the entire Cinque Terre coast from Punta Mesco.

A few days hiking (and eating) in the quiet and laid-back Cinque Terre were a great way to kick off our trip and ease us into tackling the hustle and bustle of Italy’s larger cities!


Gold Butte National Monument in Pictures

A beautiful view from our camp in Gold Butte National Monument just after sunset, looking north towards the Virgin Mountains.

Gold Butte is one of our nation’s newest National Monuments, tucked away into a small corner of Southern Nevada, northeast of Lake Mead and snuggled up along the Arizona border. Unfortunately, Gold Butte was recently recommended for a “boundary reduction.” After spending a few days exploring the areas, I can confidently say that this is a truly stunning Mojave Desert landscape, home to amazing views, endangered wildlife, unique geology, and priceless relics of the past. If nothing else, I hope these photos demonstrate that this area is worthy of more protection, not less.

Joshua Trees and red sandstone rock formations

With abundant Joshua Trees, Creosote Bush, and stark rock formations, much of the landscape is vaguely reminiscent of Joshua Tree National Park, but with the colorful Aztec Sandstone providing a wonderful ruddy backdrop to the bright green Joshua Trees.

The Aztec Sandstone in this area is without a doubt the most colorful rock formation I’ve ever seen. Much like at nearby Valley of Fire State Park, around every corner are stunning swirls of color that would look more at home in a modern art gallery than in the desert. 

Red, pink, and yellow swirls in sandstone.

We found the most intense colors on un-weathered boulders associated with recent rockfalls.

Many of the ridges and mountains in the Gold Butte area consist of Paleozoic limestones. Fossils, such as the brachiopods seen here, are a dime a dozen.

One of the primary justifications for the creation of Gold Butte National Monument was the abundance of rock art throughout the region. We saw petroglyphs pretty much wherever we went. The “Falling Man” seen here is perhaps the most well-known.

Bright pink and yellow cactus spines

Lest we neglect the living, we also saw roadrunners, kangaroo rats (one inspected our dinner one night but successfully eluded being photographed) as well as burrows made by endangered Desert Tortoises and other creatures. Somewhat more stationary and easier to capture were the bright pink and yellow spines of the California Barrel Cactus (Ferocactus cylindraceus)

I’m ornithologically-challenged; this appears to be some sort of hawk waiting patiently for it’s next meal from atop this Joshua Tree. If you know what it is, let me know!


The Many Faces of Limestone

Limestone is a unique character is the rock world. There are only a handful of rocks that can be dissolved in water, and limestone is by far the most common of that group (other members include salt and gypsum). Most limestones are composed of the skeletal remains of deceased marine organisms (a handful are formed by entirely inorganic processes), so their presence generally indicates that an area was home to a warm, shallow sea at some time in the past. Fossils of coral, clams, snails, and other water-loving critters are often abundant in limestone, and in some ways, a chunk of marine limestone IS one gigantic fossil!

The aforementioned critters make their shells out of calcium carbonate, which is soluble in slightly acidic water. Most water on Earth’s surface is slightly acidic (due to interactions with carbon dioxide in our atmosphere) so interesting things can happen when water and limestone interact…especially if you give them lots of time! In particular, groundwater is capable of dissolving huge voids in limestone bedrock over long periods of time, forming features such as sinkholes and caverns.

Limestone is an abundant rock in our neck of the woods, especially in the mountain ranges astride the Utah/Nevada border in the Great Basin. Throughout much of the Paleozoic Era (541 to 252 million years ago), this region was covered by a series of vast, warm, shallows seas, much like the one that now draws millions to the Bahamas every year.

A great place to see limestone in action is the area around Great Basin National Park. Tucked away in extreme east-central Nevada, Great Basin is one of my favorite national parks, far removed from the hoards that descend annually on many of the west’s more well-known attractions. You have to make an effort to get here and at first glance, the Snake Range of Great Basin NP looks pretty much like any other mountain island rising up out of the Basin & Range. Upon closer inspection, it’s actually home to a stunningly diverse array of landscapes: The 2nd highest peak in Nevada (Wheeler Peak at 13,065 feet), some of the world’s oldest trees, and arguably the darkest night skies in the Lower 48 all reside here.

Various cave formations in Lehman Caves

Stalactites, stalagmites, draperies, shields, and other speleothems (cave formations) abound in Lehman Caves.

But limestone is ultimately the reason a national park exists in this corner of Nevada. A small portion of the area was originally set aside as a national monument in 1922 to protect Lehman Caves, a stunning cavern eaten into the 500 million year old Pole Canyon Limestone. Only in 1986 was the monument enlarged into a National Park encompassing both the caves and the surrounding mountain landscape.

While small in size, Lehman Caves is exquisitely decorated with a wide variety of speleothems (cave formations). Stalactites, stalagmites, shields, draperies, cave bacon, cave popcorn, soda straws, and helectites surround you at every turn as you wander through the cave. Photos show details not immediately visible to the human eye in the dimly lit cave, revealing an underground world that looks more like a well manicured sci-fi movie set than a natural place sculpted by nothing more than the water, limestone, and time.

Small stalactites aligned with fracture patterns in the limestone

Baby stalactites on the ceiling of Lehman Caves trace out fracture patterns in the Pole Canyon Limestone. Groundwater containing dissolved calcium carbonate seeps through these fractures, eventually emerging into the cave where the decreased pressure causes the calcium carbonate to precipitate out of solution, forming stalactites.

Back on the surface, no trip to Great Basin NP is complete without a hike to admire some of the oldest living things on the planet: the Great Basin Bristlecone Pines (Pinus longaeva). Curiously, even these trees have an intimate relationship with the limestone that is so common here. Most of the bristlecone pine groves throughout the Great Basin are found growing on soils derived from limestone or dolomite (a limestone relative). For some reason, the bristlecones seem to prefer this rock type, perhaps because many other species do not, thus minimizing competition. The easily accessible grove on the flanks of Wheeler Peak (pictured below) is perhaps the most notable exception. Here the trees grow not in limestone, but among hard quartzite boulders deposited by old glaciers.

About an hour east of Great Basin, slightly younger (~490 million years) limestone in the House Range forms another unique feature: Notch Peak. At just 9,658 feet, Notch Peak doesn’t measure up in altitude with many other summits in the region. It’s claim to fame is its 2,200 foot sheer northwest face, one of the tallest cliffs in North America. Where exactly it ranks on that list depends on your definition of “cliff,” but there seems to be little debate that it is the tallest limestone cliff on the North American continent. The peak is striking, especially when viewed from the west, where the full magnitude of its 4,000+ foot rise from the Tule Valley below is apparent.

We spent an enjoyable evening camping in the shadow of Notch Peak and had hoped to hike to the summit the next day via Sawtooth Canyon on the east side, but unfortunately car issues derailed that plan.
