The second stop on our Alaska trip of 2019 was Wrangell-St. Elias National Park & Preserve. The largest national park in the United States, Wrangell-St. Elias spans more than 13 million acres in the wilderness of southeast Alaska. Our destination was the old mining town of Kennecott, situated deep in the park’s interior between the volcanic Wrangell Mountains and the coastal St. Elias Range.
Due to the tire issues mentioned in my last post, we opted not to take our Subaru down the 60-mile long McCarthy Road, the main access route into the park. In hindsight, we probably would have been fine, as the road was in excellent condition (at least relative to the roads we’d been used to driving in Utah. The similar-in-length Hole in the Rock Road makes the McCarthy Road look like a recently-paved superhighway). Fortunately, we were able to book a last minute van shuttle from Kenny Lake, AK to the end of the McCarthy Road. Regardless of your mode of transportation, you then walk across a footbridge spanning the glacial silt-laden Kennicott River into the town of McCarthy. (The only vehicle access to McCarthy is via a private, and very expensive, bridge a bit further downstream.) Kennecott is another 5 uphill miles by shuttle, bike, or foot:
Strangely, reaching Kennecott would have been much easier in 1919 than it was in 2019. The McCarthy “Road” is actually an old railroad grade originally built in 1909 to bring supplies in and ore out of the famous Kennecott Copper Mines. From 1911 through the late 1930s, the Kennecott mines shipped millions of tons of copper ore to Cordova on the Alaska coast via the Copper River and Northwestern Railway. The town had state of the art amenities at the time, including one of the best hospitals in the territory as well as the first X-ray machine in Alaska. While the mines closed in 1938, Kennecott Copper remains one of the larger copper-producing companies in the world, perhaps best known for the massive Bingham Canyon Mine just outside of Salt Lake City.
Following the closure of the mines, Kennecott lay mostly deserted for decades before beginning to draw tourists in the 1980s. Much of the land and buildings within the town were acquired by the National Park Service in 1998 and added to Wrangell-St. Elias National Park and Preserve. Restoration and stabilization of historic buildings in Kennecott is ongoing. Today, you can actually explore many of these buildings, including the town power plant (photo below) and the massive concentration mill (photo above), a 14-story wooden structure where copper ore was crushed and then mechanically and chemically concentrated into the high grade ore that was eventually shipped out via the railroad.
History aside, the natural landscape of Kennecott is really what makes it stand out as one of the most stunning places I’ve ever visited. The town is perched on the flanks of Bonanza Ridge, with rocky peaks towering more than 4,000 feet above and what remains of the Kennicott Glacier below. At first glance, it is not apparent (even to a geologist) that the mounds of rubble in the valley below ARE a glacier, but ice does lay beneath the veneer of debris. Like most of the world’s alpine glaciers, the Kennicott Glacier has retreated dramatically since the town’s heyday in the early 1900s, when its surface was level with or even above the elevation of the town. Today, you look down several hundred feet on to what remains of the glacier and the detritus it has brought with it out of the mountains. The origin of the glacier, and the dominant feature of the northern skyline, is the massive Mt. Blackburn, the fifth highest peak on the United States at 16,391 feet:
A few miles north of Kennecott, the Kennecott Glacier is joined by the Root Glacier, a somewhat more “normal” looking glacier that we spent nearly an entire day exploring. The experience was rather surreal given that the air temperature was nearly 90 degrees. Climates amenable to the formation of glaciers don’t often produce days where a swim in the frigid glacial melt water actually sounds appealing as opposed to horrifying, but that was certainly the case on this day.
As spectacular as the glacier was, there is something quite unsettling about walking around on one in a T-shirt. The signs and symptoms of a warming climate were all encompassing. We walked along deep gouges (surprisingly reminiscent of Utah slot canyons) carved into the ice by strong currents of melt water…
encountered many sublime pools filled with deep, electric blue pools of glacial melt water…
and carefully avoided deep shafts, known as moulins, that carry cascades of melt water into the internal plumbing of the glacier. In many places, we could hear the dull roar of the melt water boring tunnels through the ice beneath our feet. Glaciers like Root won’t survive many more summers with too many days like this one.
Despite the best efforts of the interpretive signs displaying historical photographs, and the park film showing the sights and sounds of the past, the sheer remoteness of Kennecott in 2019 makes it difficult to imagine the Kennecott of 1919: a busy town immersed in the deafening roar of copper mining, with a glacier not yet ravaged by climate change dominating the horizon.
With one job ending in June and the next not starting until September, we spent most of this past summer on the road. It’s now mid-October, and I’m finally getting the chance to seriously sort through the resulting pictures.
Our last big stop of the summer was Glacier National Park in Montana and neighboring Waterton Lakes National Park in Canada. Glacier was one of the few remaining national parks in the west I had yet to visit, so I was excited that we were able to squeeze this trip in. Despite uncharacteristically foul weather for mid-August, a harrowing experience on the park shuttle bus, campgrounds with problem bears (and problem campers), and an unscheduled detour to an auto parts store in Cardston, Alberta, we managed to get in 60+ miles of hiking among some truly first-class scenery. Our most memorable hike was the trek to Grinnell Glacier in the northeast corner of the park. Here are a few photos from that journey:
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!
The least visited and most isolated of Utah’s five national parks, Capitol Reef hosts what is perhaps the quintessential Utah landscape. It is as if someone took small portions of the other four parks and mashed them into one; here you can find a plethora of arches and natural bridges, deep snake-like canyons, soaring Navajo and Wingate Sandstone cliffs, and even a few hoodoos thrown in for good measure.
The skinny sixty mile long park was originally established as a national monument in 1937, but became a national park in 1971. The odd shape stems from the inherent nature of the feature it protects: the Waterpocket Fold, a 100+ mile-long kink in the Earth’s crust known as a monocline. Creeks and rivers have dissected the fold over millions of years to reveal what is quite possibly the most colorful and diverse array of rock layers in Utah.
Capitol Reef is far from just about everywhere (which made the flat tire we experienced on the way that much more annoying). To the east and south lie the last major mountain range and river, respectively, to be mapped and added to the map of the lower 48 states. Not until the 1960s did a paved highway cross the Waterpocket Fold through Capitol Reef. In the northern part of the park, the Fremont River slices a narrow canyon through the Waterpocket Fold, its water creating one of the few habitable areas in the entire region. Petrogylphs attest to the importance of this year-round water source to ancient inhabitants. In 1880, Mormon settlers established the settlement of Fruita along the banks of the Fremont. The remains of this historic farming community and the abundant, lush green orchards and fields seem out of place in the otherwise stark central Utah canyonlands but add to the allure of the park.
Here are some of the sights from our quick trip to Capitol Reef this past weekend:
For the most part, the landscape at Capitol Reef is quite open, allowing vast views and superb light at sunset:
Not far from the park campground and visitor center are the remnants of an old trail leading up a sandy wash, then up a short but steep talus slope before arriving at a hidden basin containing hoodoos and other strange rock formations. Unfortunately it was just about noon and the light was about as direct and harsh as possible, but it was cool to explore an area off-the-beaten path yet still in sight of the tour buses below:
I grew up about 90 minutes away from Petrified Forest National Park and, aside for a quick lunch stop about 10 years ago, had never visited before last week. While this is nowhere near as inexcusable as living in Arizona for decades and never visiting the Grand Canyon (yes, such individuals exist…I’ve met many), it still seemed like a bit of an oversight on my part. Or it could simply be a reflection of the inordinate number of outdoor activities that exist in northern Arizona; even living in the area for 10+ years isn’t enough time to hit everything. Either way, after finally venturing into the Petrified Forest, I can emphatically say that it should be mentioned with the best that northern Arizona has to offer.
Located amongst the vast Painted Desert of northeastern Arizona, the main attraction of Petrified Forest is of course the petrified wood. The formation of petrified wood is initiated when downed trees are quickly buried by sediment. Once entombed in the sediment, the lack of oxygen prevents the logs from decaying as they normally would when exposed directly to the atmosphere. In this case, the logs (none of which remain standing, despite the name “Petrified Forest”) were likely brought here in massive logjams along an ancient river system that existed during the Triassic period. A combination of sediment from the river and ash from nearby volcanoes buried the logs, not to be seen again for more than 200 million years. During this time, as the logs became buried under an increasingly deep pile of overlying sediment, dissolved silica began to crystallize in the pore spaces of the wood as quartz, eventually replacing all of the organic material while maintaining the original shape and structure of the log.
Petrified wood is not particularly rare. Good examples abound in Yellowstone National Park, Washington state, Utah, Colorado, Oregon, Alberta, New Zealand…the list goes on and on. What makes Petrified Forest National Park unique is the quantities found here. Due to the aforementioned Triassic log jams, large quantities of wood were concentrated in small areas. In a location known today as Jasper Forest (see photos below), movement was not possible without walking over a nearly uniform carpeting of small petrified wood fragments and frequently having to clamber over 2-3 foot diameter logs. Truly stunning!
Another unique aspect of Petrified Forest is the colorful canvas on which the wood is found. The wood is eroding out of a rock unit known as the Chinle Formation, which essentially consists of all of the river sediment and volcanic ash the buried the trees in the first place. More than 1000 feet thick in the park, the Chinle Formation is composed primarily of extremely soft mudstones, clays, and volcanic ash. Water is able to easily sculpt the soft rock into fantastically colored and oddly shaped badlands that make a spectacular backdrop for the logs.
Petrified Forest National Park faces an issue not encountered by most other national parks, namely, the wholesale theft of the very resource it was established to protect. For this reason, the park is only open during daylight hours (from 8-5 in the winter) to minimize opportunities for looting. It strike me as very sad that such measures are necessary. With a little geological perspective, it becomes clear how incredibly lucky we are to experience a landscape like Petrified Forest at this moment in time. So easily eroded is the Chinle Formation that in many locations, several inches of it are removed each year. This may not sound like much, but geologically speaking, that’s a veritable bullet train of erosion. While it took tens of millions of years for the Chinle to be deposited, it will be erased from our planet by the unceasing forces of weathering and erosion in a tiny fraction of that. The petrified logs, being comprised mostly of silica, are harder and will last a little longer, but are still brittle and will eventually be washed into the Little Colorado River and swept downstream along with the colorful Chinle badlands.
What all this means is that the colorful Painted Desert/Petrified Forest landscape we see today is one that is extremely temporary. While this is true of most landscapes we see on Earth today—our planet likes to re-build, re-arrange, re-shape, and remove constantly—the Painted Desert is even more ephemeral than most. While mountain ranges comprised of harder, erosion-resistant granite or quartzite (like most of the Rockies) can stand the test of time to some degree, the longevity of the Painted Desert, its soft sediments, and its brittle petrified wood is comparatively brief. Stealing this treasured natural resource only abbreviates our time with the Petrified Forest even more.
While Zion National Park may not normally be known for its waterfalls, spring snow runoff and the occasional summer monsoon thunderstorm can turn the park and its stunning red and white sandstone cliffs into a veritable Yosemite of incredible waterfall action.
I made a brief stop in Zion as part of a 1200 mile drive from Washington to Arizona for the holidays. I had visited Zion in the past during the spring when runoff from the high country surrounding the canyon was at its peak but despite the fact that the entire western United States had been getting hammered by a massive cold front for the past 2 days, I never expected to see the number of waterfalls that I did. Not only were they more numerous then ever before, even the relatively reliable ephemeral waterfalls, such as the one near the parking area at Temple of Sinwava, flowed with significantly greater gusto that I had ever seen before.
For an interesting comparison, here’s a shot taken from almost exactly the same spot (notice the bare tree on the left is the same as the tree on the right in the previous photo) in the summer of 2009.
Perhaps the most spectacular waterfalls were those found in the small alcove that is home to Weeping Rock. A short but wet hike up the Hidden Canyon Trail provided a vantage point of these falls. Getting decent photographs was a challenge. With heavy rain, wind, and nearly 100% humidity, it was next to impossible to keep rain off the camera and keep my lenses from fogging up.
The day after these photos were taken, the entire Park was shut down and evacuated due to severe flash flooding, road washouts, and the threat of a dam failure upstream on the Virgin River.
