Exploring Southwest Idaho, Part 3: The Snake River Canyon and Birds of Prey

by Alan K. Lee

The roughly 100 mile (as the crow flies) stretch of the Snake River, from south of Boise to just west of Twin Falls, is a geologically interesting area, wildlife is abundant, the scenery is outstanding, and there’s plenty there for those interested in the history of the American West, as well. Thousand Springs, Balanced Rock, Bruneau Dunes, and the Snake River Canyon are all beautiful, unique, and well worth visiting.

Snake River Birds of Prey

People from all over the world come to the Morley Nelson Snake River Birds of Prey National Conservation Area to view, photograph, and study the hawks, owls, eagles, and falcons that make the Snake River Canyon home. And Boise is home to the World Center For Birds of Prey, the home base of the Peregrine Fund, a non-profit environmental organization that played a key role in bringing the Peregrine Falcon back from the brink of extinction. The Peregrine Fund now runs raptor recovery and protection programs around the world. The canyon is not just for hardcore birders, though. It is spectacularly beautiful for one thing. And there are cultural and historic attractions as well.

There are two primary access points to the Snake River Canyon in the Birds Of Prey NCA – Swan Falls and Celebration Park. Our first stop was the Dedication Point Overlook on the rim of the canyon above the Swan Falls area. The canyon here is about 600 feet deep, with sheer vertical walls several hundred feet high below the rim. There was a group of photographers there attempting to get photos of raptors. We saw a few hawks soaring overhead, but too high to get decent photos. It’s a scenic spot, though, and we hung around for awhile, before heading down to Swan Falls.

The falls are long gone, flooded by construction of Swan Falls Dam in the early 1900s. Swan Falls was the first hydroelectric project on the Snake River. A fish ladder was constructed, but was largely ineffective, and the dam effectively blocked salmon and steelhead passage. That was a different era, and the fish ladder was never made functional. Newer dams were built both upstream and downstream with no fish ladders at all. Electricity was the point. The fish didn’t matter. But it’s a historically interesting and beautiful area, so it’s worth a visit even if, like me, you’d rather see the dam gone.

A new power generation facility was constructed at Swan Falls Dam in the 1990s. The dam’s original power plant is now open to the public, with some of the century-old generators and other equipment still in place. There are also displays depicting the history of the area, and the construction and operation of the dam. We walked across the dam after visiting the power house museum, then drove down the canyon a ways. The road was too rough for the car, though, and we turned around and drove back up to Dedication Point, and then on to Celebration Park.

Celebration Park is Idaho’s only archaeological park. Petroglyphs dating back as far as 10,000 years can be found there. Visitors can learn about the Native American “lifeways” at the visitor center, try their hand at throwing a spear with an atlatl, and explore the petroglyph area on a self-guided walk.  There is a picnic ground, and a small tent campground. The visitor center is open from 10:00 to 2:00 daily, except holidays. Check the park website for more information and possible Covid-19 closures and restrictions.

A short ways downstream, the Guffey Railroad Bridge provides pedestrian and equestrian access to the south bank of the Snake River and the Guffey Butte area. The bridge was built in the late 19th century and carried rail traffic until the 1940s. It is listed in the National Register of Historic Places. Guided tours of the area highlighting the area’s early mining and railroad history are conducted periodically.

Hikers will find trails on both sides of the river. On the north side a trail follows the river upstream for about five miles to the end of the road from Swan Falls Dam. A side trail leads to Halverson Lake, nestled against the cliffs of the canyon wall.

We didn’t have time to do any hiking at Celebration Park, but the trail to Swan Falls would be an interesting outing, and a good place to do some serious raptor watching, if you’re so inclined, away from most of the human influences in the Conservation Area.

Back in Boise, we toured the World Center For Birds of Prey the following morning. The staff there are friendly and knowledgeable, and dedicated to the mission of educating the public about birds of prey and protecting the vulnerable populations of raptors around the world. We sat in on a talk given by two of the staff that was fascinating, informative, and entertaining.

There are a number of raptors from around the world on display there, birds that for one reason or another could not be returned to the wild. Being able to see these magnificent birds up close was a highlight of our trip. The center is also home to a pair of California Condors, North America’s largest bird, that are part of the captive breeding program that has helped save the species from extinction.

For more on Boise, a lively, surprisingly cosmopolitan city that still has a small town vibe, look for my next post, coming soon.
