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.

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.

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:

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!)
Slots of Fun in Cottonwood Canyon

The 47 mile-long Cottonwood Canyon Road slices through some of the most otherworldly terrain in Southern Utah, connecting Highway 89 in the south with the Bryce Canyon region in the north. Mostly unpaved, some GPS devices have been known to lead travelers down this road in the name of a shortcut to Bryce Canyon National Park. When dry, Cottonwood Canyon makes for a wonderful scenic drive and is indeed a shortcut. But in the days following rain or snow, the layer of clay-rich shale the road follows for most of its length turns into a veritable morass, and renders the road impassible regardless of how many-wheel drive your vehicle might possess. Coming from the south, the road initially follows the broad valley of the Paria River drainage, before leaving the river behind and heading up the narrower valley of Cottonwood Creek. This portion of the road passes through Grand Staircase-Escalante National Monument; other sections used to as well before the monument experienced its recent “downsizing.”
We recently took a three-night camping trip to explore Cottonwood Canyon and some nearby areas. Our first stop was Yellow Rock, near the south end of the road about 13 miles from Hwy 89. Yellow Rock is a massive dome of Navajo Sandstone, easily visible from the road as is rises high above the jumble of rock layers alongside Cottonwood Creek. While the hike to its summit is not long, getting there requires a moderately-difficult scramble up a hidden rocky chute littered with loose boulders. Hiking poles/sticks highly recommended. After scrambling to the base of the rock, the real fun begins. After a few years living in Southern Utah, it is natural to assume that you’ve seen every color, pattern, and texture of sandstone that can possibly exist, but then Yellow Rock comes along and proves you wrong:

While the abundant cottonwood trees lining the canyon bottom were still quite leafless, even in early April other signs of spring were beginning to show in this high desert. Traversing across Yellow Rock, we encountered many pockets of Desert Paintbrush, Anderson’s Buttercup, and Manzanita in sandy stream bottoms or in crevices in the sandstone, already in full bloom:

For over a dozen miles, the Cottonwood Canyon road parallels the “Cockscomb”, a jagged ridge of resistant sandstone tilted to near-vertical. Here, varicolored rocks of the Carmel and Entrada Formations line the road near the Cottonwood Canyon Narrows trailhead.
On our final night, we camped near the north end of the road, not far from Kodachrome Basin State Park, where we were treated to a spectacular sunset and even more stunning dark, moonless night skies:

No Southern Utah camping trip would be complete without a saunter through a slot canyon, so on the way home in the morning, we made a quick detour to Willis Creek Canyon. At the beginning of our trip, we had briefly probed the famous Buckskin Gulch, just south of Cottonwood Canyon in Arizona, but were quickly turned back by waist-deep mud & debris pools that were emanating quite possibly the most foul stench to ever besmirch this Earth. In contrast, Willis Creek Canyon is a rare bird in Southern Utah; a beautifully sculpted slot with no technical obstacles to rappel over, and no putrid cesspools to wade through. Instead, a small babbling brook winds through the sandstone narrows, seemingly oblivious to its own high-quality handiwork:
