Happy New Year! For the first time since 2019, we were able to visit family in Arizona for the holidays this year. (We had tickets last year, but Southwest Airlines had other plans…) The cheapest flights were into Tucson, so I got to spend a few days hiking and shooting photos in the sunny and 75° Sonoran Desert for a few days at the beginning of the trip. It was a lovely break from the cold, gray central Washington winter, and it is hard to come away from an Arizona sunset without at least a few good photos! Here are a few of my favorites:

A crested saguaro in Saguaro National Park, Arizona. According to the park, crested saguaros “form when the cells in the growing stem begin to divide outward, rather than in the circular pattern of a normal cactus.” The cause is unknown, and only a few thousand crested saguaros have been documented.

More Spring Wildflowers (this time with spines!)

One of our favorite times of year when living in southern Utah was late spring, when the desert would come alive with a wide variety of vibrantly colored cactus blossoms (which were soon followed by delicious fruits that made superb sauces, beer, and margaritas!) Central Washington is a bit lacking in the cacti-department, but we do actually have a few species that can put on a springtime show if you know where to look. 

The most widespread species is the Columbia Prickly Pear (Opuntia columbiana), however I’ve yet to see any flowers. I am beginning to suspect that this species blooms only in certain years with the proper moisture conditions, though I haven’t been able to confirm this. 

Another species, a variety of hedgehog cactus (Pediocactus nigrispinus), is harder to find, but quite reminiscent of the stout barrel cacti of Utah, Arizona, and Nevada. Once more common in central Washington, Pediocactus nigrispinus has sadly been the target of illegal collecting and poaching, reducing its numbers to the point that it is now a threatened species here in Washington. We’ve run across patches of this cactus on two recent hikes, and the second time we were delighted to find many of the buds in bloom. This little cactus, robust but generally no more than a few inches high, has electric-pink flowers that really stand out, even when surrounded by tons of other spring flowers on the sagebrush steppe.

And for good measure, a few other flowers from recent excursions:

Tips on identifying specific balsamroot or lupine species are welcome! There seem to be dozens of different varieties out here, but I sure as heck can’t tell them apart…


Wildflowers and Waterfalls of the Columbia River Gorge

Looking east along the Columbia River Gorge toward The Dalles on an alternately sunny & rainy March afternoon. 

In the home stretch of its more than 1,000 mile-long journey from the Canadian Rockies to the Pacific Ocean, the Columbia River has carved a spectacular canyon that now forms the border between Oregon and Washington: the Columbia River Gorge. Nearly 100 miles in length, the Columbia River Gorge is one of the most unique landscapes in the Pacific Northwest, and home to some spectacular geology. Most of the gorge is carved into the Columbia River Basalts, layers upon layers of volcanic rock formed by vast lava flows that inundated most of central and eastern Washington about 16 million years ago. More recently, a series of large glacial outburst floods at the end of the last ice age broadened and re-shaped the gorge as they raged their way down the Columbia River to the Pacific Ocean, creating many of the landforms that we see today.

By the time the Columbia River enters the gorge, its elevation has already dropped to just 160 feet above sea level. The low elevation of the gorge makes it one of the warmest areas in the Pacific Northwest, and a prime destination for some early season camping. We recently spent three days in the Columbia River Gorge soaking up what passes for balmy weather this time of year around here.

Motorcycle headlights illuminate the sweeping curves of the Historic Columbia River Highway just below Rowena Crest. The constellation of Canis Major sits just above the horizon. While the historic highway has been largely replaced by the much less charismatic I-84, large portions remain as backroads or hiking trails.

Two of the main attractions in the Columbia River Gorge are wildflowers and waterfalls. Even now, in mid-to-late March, the wildflower show was already in full swing, particularly in the drier, warmer, eastern reaches of the gorge:

Shooting stars (Dodecatheon sp.) are among the early blooming wildflowers in the eastern Columbia River Gorge. A yellow fritillary (Fritillaria pudica) lurks in the background.

Grass widows (Olsynium douglasii) are some of the earliest wildflowers to bloom in large numbers in the eastern Columbia River Gorge.

More grass widows…

Most grass widows are a vibrant pinkish purple color, but white petals are also found here and there.

One of the most remarkable sights in the Columbia River Gorge is experiencing the rapid change in environment as you drive through the gorge from east to west. The Dalles, located near the eastern end of the gorge, lies in the rain shadow of the Cascade Range and receives very little precipitation: just 14 inches annually. Here, the rocky slopes of the gorge are nearly devoid of any vegetation other than wildflowers and grasses. Just half an hour and a handful of freeway exists to the west, the average annual precipitation has increased to about 30 inches at Hood River, and ponderosa pine and Douglas fir cover the slopes. 20 more miles/minutes to the west, at Cascade Locks, annual precipitation rises to over 75 inches and the gorge is filled with the dense, shady, and mossy forests typically associated with the Pacific Northwest. In other words, you can travel from a true desert to a near-rainforest in less than an hour, while driving on a nearly flat interstate that hugs the shore of massive reservoirs created by dams along the lower Columbia River.

Large clusters of balsamroot (Balsamorhiza sp.) were beginning to flower in some of the drier, eastern parts of the Gorge, like these at Horsethief Butte.

Fungus and moss grows on a rotten log on the forest floor

An unknown species of fungus shares a decaying log with some moss. Scenes like this are common in the wetter, western half of the Columbia River Gorge.

The combination of dramatic terrain and copious precipitation at the western end of the Columbia River Gorge (particularly on the more mountainous Oregon side) combines to form some of the most spectacular waterfalls in the United States. As the aforementioned ice age floods flowed through the gorge on their way to the Pacific, they removed the lower ends of valleys belonging to the Columbia’s many tributary streams. Consequently, many of these tributaries enter the gorge several hundred feet above river level, terminating in spectacular plunges that carry their water into the Columbia River:

Latourell Falls plunges over a cliff of columnar basalt at the western end of the Columbia River Gorge, not far from Portland. This photo is a bit blurry; the trails to several of these waterfalls were busy, even on a somewhat chilly Tuesday in March, making it hard to set up a tripod for a steady shot.

Let’s be clear: with temperatures in the 40s and 50s and the nearly constant winds that blow through the gorge, it was no spring break in Florida, but after a long winter and with the Cascades still buried in snow for several more months, the greenery and signs of spring were a welcome sight. (Even though we did have our tent totally chewed up by an unknown animal…a first for us in many, many nights of camping throughout the west!)
