The last destination on our Alaskan journey was the Kenai Peninsula and the town of Seward. After a few days respite from the wildfire smoke in Wrangell-St. Elias, it returned with a vengeance as we headed back to Anchorage and down to the the coast:

After baking in the heat of the Alaskan interior for the last week, the marine climate of Seward was a welcome change. We even had a bit of rain for one of the few times in our entire trip.

While temperatures in Seward we’re somewhat more mild, the coastal location meant the humidity was not. On our first day in Seward, we partook in a brutal hike up to the Harding Icefield in Kenai Fjords National Park. The hike itself was not abnormally difficult, but we were definitely not used to the combination of heat and humidity, leaving me feeling physically ill at several points during the slog up the mountain. The day had started off overcast, but as we climbed, the clouds evaporated leaving us with stellar views of the rapidly retreating Exit Glacier and the Harding Icefield from which it originates. An icefield is essentially a large mass of interconnecting glaciers. The Harding Icefield is the largest — and one of only four — remaining icefields in the United States. The Exit Glacier itself has retreated more than a mile in the last 200 years, leaving trees and other vegetation to begin re-occupying it’s former valley.

The white and blue ice of the glacier made for a stellar contrast with the lush green vegetation of the alpine zone:

The wet climate of coastal Alaska results in extremely heavy snowfalls, making this one of only a handful of places in the world where glaciers flow all the way down to sea level to meet the ocean. Known as tidewater glaciers, these glaciers exhibit complex patterns of advance and retreat that, unlike standard alpine glaciers, are not purely the result of variations in climate. While warmer temperatures or prolonged drought can certainly reduce their mass, the movement of tidewater glaciers is also subject to complex interactions between the ice, the geomtery of the ocean floor, and the depth of the water into which they flow.

On our second day in Seward, we took a water taxi into the heart of Kenai Fjords National Park and then kayaked to within about a quarter mile of the terminus of Holgate Glacier. Tidewater glaciers have a tendency to “calve”, in which large chunks of ice break off the glacier and fall into the ocean, necessitating a safe distance. Glacier “social distancing” if you will. It is not hard to find videos on YouTube of people getting too close to calving tidewater glaciers, with quite predictable results. From our safe distance, we observed and heard several calving events in the few hours we were kayaking around the bay, but unfortunately I was not adept enough at kayaking into position quickly enough to actually capture one on camera.

Our boat ride back to Seward through Resurrection Bay also resulted in sightings of sea lions, seals, puffins, and even two pods of orcas: an exciting end to the trip!

Crossing the Channel

Just a few dozen miles off the coast of Southern California lie the Channel Islands, eight motes of land jutting out of the sea a stone’s throw from the hustle and bustle of the Los Angeles metropolitan area. Of the eight islands, the only one with a significant human population is the tourist mecca of Santa Catalina, which draws over one million visitors per year. The remaining seven islands are sparsely populated and draw far fewer tourists. The four northernmost islands form an archipelago that is protected by Channel Islands National Park and the Nature Conservancy.

Back in March, we briefly visited the largest Channel Island: Santa Cruz. At 97 square miles in area, Santa Cruz is reached via ferry from Ventura or Oxnard. Our hour-long journey across the Santa Barbara Channel was choppy to say the least, but included close up views of Pacific white-sided dolphins and several majestic oil drilling platforms. Upon arrival, we were greeted by one of the most lush landscapes imaginable. Abnormally abundant winter rains had produced a tall, dense carpet of green grasses that blanketed the entire island. One of the resident rangers told us it was the greenest he had seen Santa Cruz in the seven years he’d worked there.

Given their relative geographic isolation, the Channel Islands are notable for their high concentration of endemic plant and animal species found nowhere else on Earth. They are also home to some of the earliest evidence of human habitation in the Americas. Archaeological and geological evidence suggests that humans inhabited Santa Rosa, just east of Santa Cruz, as far back as 13,000 years ago. At this time, sea levels were much lower due to the massive amounts of water locked up in glaciers and ice sheets farther north. As a result, the four northernmost islands (Anacapa, Santa Cruz, Santa Rosa, and San Miguel) were united into a “mega island” whose eastern edge was much closer to mainland California. This made it easier for plants and animals to reach the island, either by air (birds, plant seeds, etc.) or on floating rafts of debris (mammals, reptiles, etc.) Some species may have even been deliberately brought to the islands by humans.

As the most recent glaciation ended, sea levels began to rise, eventually splitting the mega-island into the smaller landmasses that exist today. Once isolated, the plant and animal populations that had established themselves on the islands, either organically or after being brought there by humans, began to evolve into species distinct from their mainland cousins. In some cases, distinct subspecies have evolved on individual islands in response to unique conditions.

For visitors to Santa Cruz, the most obvious example of this phenomenon is the ubiquitous Santa Cruz island fox (Urocyon littoralis var. santacruzae). Coming from the mainland where a sighting (especially a daytime sighting) of a fox is a rare treat, we were surprised to see one within minutes of getting off the ferry. The island fox is descended from and appears very similar to the common grey fox, but is much smaller. A fully grown island fox weighs just 4-5 pounds, and is similar in size to a large house cat. Often the lush spring grasses exceeded the foxes in height, making them challenging to spot! Nearly extinct in the early 1990s, a highly successful habitat restoration and captive breeding program has the species thriving today. We ended up seeing several dozen in our short visit to Santa Cruz. Other subspecies of the island fox exist on five of the other seven islands, each with slight differences evolved in response to local conditions.

With its pastoral landscape and unique wildlife, Santa Cruz feels a world away from metropolitan areas of Southern California. However, nightfall brought a stark reminder of just how close the islands are to the urban sprawl. Light pollution from Los Angeles, Oxnard, Ventura, Santa Barbara, and the numerous oil drilling platforms in the Santa Barbara Channel dominated the night sky from Santa Cruz.

Our return trip was delayed because the choppy seas prevented the ferry from reaching the anchorage on Santa Cruz on time, giving us a few extra hours to sit on the beach and enjoy the peace & quiet of the island. The winds died down enough for a smooth ride back across the channel where we even spotted a couple of migrating gray whales. Apparently I need more practice shooting photos from a moving platform, as the whale pics all turned out pretty blurry. Have another fox instead!

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 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!
