Idaho Falls, Idaho

On Friday, July 29 as we followed the emigrant trail headed east on Interstate 86, we were channeling our inner Willie Nelson and singing “On the Road Again.” So far, the truck troubles we encountered in Sparks and Elko no longer conspired against us.

We stopped at Massacre Rocks State Park and Register Rock to eat our lunch and have a quick look around. Panels outside of the visitor center, tell the story of Massacre Rocks, a narrow passage along the Oregon Trail (now Interstate 86) where emigrants often stopped to camp. The boulders, also known as “Gate of Death,” or “Devil’s Gate,” were so named because emigrants feared attacks by the Native Americans. Documented accounts of massacres and attacks took place east and west of the rocks during the 1850s and 1860s. Register Rock, protected by fencing and a shelter against the elements and persons intent on destruction, contains the names and dates of many emigrants who passed through the area.

As Jon and I guessed, we found Idaho Falls similar to Twin Falls with an abundance of water and farmland. Once we had settled in at the Snake River RV Park and Campground, we headed downtown where we found a park alongside the Snake River. We marveled at the smooth, calm waters on one side of the river, which flowed over the side onto rocks and boulders creating the falls. It definitely looked man made, but for what purpose?

We continued along the river walk where tall trees provided shade along a path lined with benches. We passed families with strollers, couples holding hands, and a father and son with fishing poles wagging over their shoulders. Then we came across the Idaho Falls Hydroelectric Bulb Turbine Project sign. I had never heard of this kind of power plant, could we possibly take a tour? We would have to wait until Monday to find out.

Needing to replenish our fresh fruit and vegetable bins, we checked out the Saturday Farmers Market. At first, we were disappointed when crafts dominated the booths. But it turned out that the empty lot on one side of the street was for the craft vendors and the produce vendors were set up in the parking lot behind a bank, along with face painting for the kids, kettle corn, bread, jams, and sauces.

Afterward, an offer of “Free Taters for Out-of-Staters!” enticed us to visit the Idaho Potato Museum. They have a short video on growing and cultivation of the potato. A timeline depicts the introduction of the potato from the Andes to Europe by the conquistadors in the 1500s through the early 1800s when Henry Harmon Spalding, a Presbyterian missionary, introduced the potato to the Oregon Territory in 1836. Also included is the development of the Russett Burbank, or Netted Gem. Historians believe Mormon colonists were the first settlers to plant, grow, and harvest the tuber three years before Idaho joined the Union as a state.

A few things I learned about potatoes:

  • the potato plant and its berry-like fruit are poisonous to animals and humans,
  • farmers can harvest the spuds anytime after the plant dies back and before the first freeze,
  • don’t store potatoes with onions because they emit gasses that cause faster spoilage when they are together.

Oh, and our reward for touring the museum? A box of Hungry Jack Cheesy Scalloped Potatoes. Yum! A side dish to pair with barbecued chicken.

Craters of the Moon National Monument and Preserve was our next outing. As we drove up the road toward the park, visions of the Hawaiian Islands lava flows came to mind when we spotted miles and miles of lava rock, cinder cones, and buttes created between 2,000 and 15,000 years ago by the Great Rift volcanic eruptions.

The monument, at an average elevation of 5,900 feet above sea level, includes three lava fields and about 400 square miles of sagebrush steppe grasslands for a total area of 1,117 square miles. The monument receives between 15-20 inches of rain per year that eventually appears in springs and seeps in the walls of the Snake River Canyon. Now we know at least one source of all the water we saw in Twin Falls, Idaho.

Craters of the Moon was the best example of the National Park system I have seen. With well-maintained paved roads, above par signage with stats on trail mileage, elevation increases/decreases, and even the width of the path, it looked to be a model for other facilities. The park service is currently redoing the campground and as I imagined the landscape draped in moonlight, the word spooky came to mind.

We poked our heads in Dewdrop Cave, but we weren’t prepared like other visitors with their headlamps strapped around their foreheads. A permit is also required to enter Dewdrop and three other caves that spelunkers can explore. I think my favorite part was seeing the out-of-place pine trees, monkeyflower, syringa, and bitterroot growing from the basalt on the older lava flows, the little ground squirrels scurrying around, and pygmy rabbits blending in with the scenery.

We would like to return to Craters of the Moon someday, spend more time, maybe even venture into a couple of caves, and experience the place at night. Although, snagging a spot at the new campground might be a challenge.

On our way back to base camp we stopped at the yellow structure created by John Grade titled Spur, which was inspired by the lava tubes at Craters of the Moon.

Further up the road in Arco, stands a hill speckled with numbers. Each year, high school seniors paint the year of graduation on the hill.

The day had arrived for our private tour of Idaho Falls Power. We learned of the Teton Dam collapse in 1977 that destroyed an existing electric power plant along the river and that the construction of the Bulb Turbine project occurred between 1978 and 1982. Matt Evans, our tour guide, led us downstairs to a hatch in the floor that allowed us to see a turbine casing. They are similar in size to the ones used at Shasta and Hoover dams except they are placed on their sides, not upright.

The water flows through the facility at one end (picture with branches in the water) to power the turbines and exits at the other end (picture with swirling water) to continue its journey to Twin Falls and beyond. We had driven by the building a few days earlier and never guessed there was a power plant below the river surface. The distinctive landmark is the orange and white water tower shown in the farmer’s market picture above.

The apparatus we saw along the river walk diverts water for use at the power plant and releases the excess to create the falls. The plant channels 6000 cubic feet per second of water through the turbines to produce up to 8000 kilowatts of energy each. There are two other plant sites in the city and combined they produce approximately 100 million kilowatt-hours of electricity annually.

After the tour, we drove around town and found The Protector, an eagle monument believed to be the largest in the world. Created by Vic Payne and installed in 2006 for McNeil Development, it is the focal point in the center of a roundabout.

With clean clothes, a stocked refrigerator, and reservations at Yellowstone Mountainside KOA, we were ready to hit the road again for our next adventure.

Twin Falls, Idaho

Golden-brown russet  potatoes, the kind we use for Thanksgiving dinners, came to mind as I switched the map from Nevada to Idaho. But I will forever associate Twin Falls, Idaho with water. Twin Falls is one of eight counties in south-central Idaho known as The Magic Valley. In the early 1900s, an enterprising individual convinced investors to build a canal system to carry water from the Snake River to the surrounding desert populated with sagebrush and grass. Remove the sagebrush, add water, and poof. Out pops fertile farmland.

Lush bright-green acres of potatoes, kale, and corn welcomed us as we neared Twin Falls. Golden fields of hay ready for harvest along with cattle and dairy farms rounded out the agricultural offerings. Our jaws dropped when we passed the first of many farms with giant Rainbirds spraying water on the crops and swamping the fields. Coming from California where every drop is precious and conservation is drilled into the residents at every turn, we could only think how wonderful it would be to have access to such an abundance of water. The reddish-orange color in the sunset sky is smoke from fires burning near Boise, 150 miles northwest from Twin Falls.

Water, Water, Everywhere

We arrived at Anderson Camp RV Park, our new home for the next three nights, on July 26. The park offered shady, grassy spots with plenty of space between the neighbors. Anderson Camp is a well-maintained older park with a pool and twisty waterslide (for an extra fee). They have cabins to rent and space for tents. If we stop here in the future, we’ll be sure to ask for a site without a walnut tree. The birds and squirrels stripped the nuts of their shells and scattered the debris all over the picnic table, trailer, and truck and in the morning, we woke to little bombs hitting the roof of the trailer.

On the drive down the gorge toward Shoshone Falls, water gushed from the basalt canyon walls. One of the locals told us it was the dry season since the farmers had diverted much of the water to drench their crops. His definition of ‘dry season’ was wildly different from ours after living in a drought state for five years.

The Shoshone Falls reminded me of a miniature version of the Niagara Falls. I can’t imagine what the water cascading over the boulders would be like at full strength. We saw pictures that showed the falls stretching from one side of the canyon to the next.

Dierkes Lake and the adjacent park, a favorite for residents and visitors alike, offers swimming, fishing, and picnicking in the cool shade of the large trees.

The current Hansen Bridge, built in 1966, spans 258 feet and is 350 feet tall. It replaced a suspension bridge built in 1919. Before the bridge was built, travelers used rowboats to cross the gorge. More smoke is evident on the horizon.

A kiosk on the south side of Hansen Bridge described the impact on the Snake River Plain from the Lake Bonneville Flood, which is believed to have occurred 15,000 years ago. Imagine a late Pleistocene lake covering 19,691 miles in northwest Utah releasing water at a rate of 15 million cubic feet per second into southeastern Idaho and on to the Columbia River in Oregon. The Great Salt Lake in Utah is what remains of Lake Bonneville. Also noted was how the emigrants followed the river on their way to Oregon stopping for a respite in Twin Falls. Another board told of entrepreneurs who developed the canal system promising a Magic Valley, and of other people who provided the goods and services to the new inhabitants of the territory or transport across the divide.

Twin Falls Visitor Center offers maps and pamphlets of other sites to see in the surrounding areas. A walk under the highway leads to The Twins sculpture crafted by David Clemons and provides one of many perspectives of the Perrine Bridge that rises 486 feet above the Snake River. Its span is 1500 feet from rim to rim.

On our way to Hagerman Fossil Beds, we came across the Hagerman Sheep Monument, a tribute to the Basque sheepherders who settled in the area. The monument included statues of sheep, a sheepherder, and a replica wagon equipped with stove, sink, and bed just like a small trailer you might see today.

Access points along the Snake River provide fishing, swimming, and boating. Loaner life vests are also available at some boat launches.

Another side trip was The Hagerman National Fish Hatchery. Outside in a demonstration pond, sturgeon and trout swam in the shadows.

Inside the building, we saw the zillion little fish in the tanks that one day will be planted in the lakes and river.

We never did make it to the fossil beds. The ranger at the Forest Service Office recommended Thousand Springs State Park and Ritter Island instead due to the hot weather. More falls, water gushing from the canyon walls, and ankle-deep water  provided  a break from the heat of the day.

The Thousand Springs Hydroelectric Power Plant acquired in 1916 and updated in 1921 generates 8800 kilowatts. The castle-like architecture creates a sense of whimsy to what would otherwise be another hunk of concrete and steel.

Our last day in Twin Falls, we went to the Rock Creek Station and Stricker Home.

The cabin building in the photo was a store, a post office, and polling place from 1879 – 1897. The mounds behind the building are cellars, one wet, and one dry. I wanted to look inside the dark earthen cave, but thick cobwebs draped the doorways. No way was I going to pass through them into a spider infested space. To the right of the store once stood a station where stagecoaches stopped to change out their horses.

Rock Creek Station

A creek runs behind the white house that was built in 1901. Apparently, there were up to forty buildings during the stagecoach days. This property must have been an oasis after traveling in a stagecoach across miles of dry land and sagebrush. Tours of the fully furnished house are available.

One last stop before we headed off to Idaho Falls. Centennial Waterfront Park is a great place to rent a kayak, eat a picnic, hike the trails, find rocks to climb, or . . .. We walked along a path at the water’s edge under shade trees and watched the kayakers glide across the water.

After three fun-filled days, it was time to move on. “Idaho Falls, here we come.” I expected to see a lot more water coming our way.
