Circle Tour - To Salmon, Challis & Custer Motorway Adventure Road

We took another two day, overnight, circle trip, Thursday (6/18) and Friday. We drove northwest through the Lemhi River Valley (US 28) to the town of Salmon.  We then followed the Salmon River Gorge south to Challis for the night. Friday morning we visited the ghost town of Bayhorse and followed the 43 mile Custer Motorway Adventure Road from Sunbeam back to Challis and then returned home.

Used in silver and lead smelting operations.

After lunch we visited the Sacajawea Interpretive,
Cultural and Educational Center

Lewis and Clark Expedition.

Challis Hot Springs Bed & Breakfast
Originally this boarding house was developed in 1890
to support the local mining operations.

Two natural hot spring pools are located on the property.
Hot water bubbles up through the gravel bottom at
a rate of three cubic feet per second.

The mining ghost town of Bayhorse is now
operated by the Land of the Yankee Fork State Park.

In 1872  a lead-silver vein was discovered that resulted in
the creation of the Bayhorse Mining District in 1877.
In the end the town reached a population over 300.
Over 100,000 tons of ore was removed.

The Custer Motorway Adventure Road, also known as the Yankee Fork Historic Mining District Driving Tour, was the original Toll Road, constructed in 1878. This 43 mile one lane gravel road takes travelers past numerous historic and scenic vistas between Custer and Challis. Along the way we passed the ghost towns of Bonanza and Custer as well as the Yankee Fork Gold Dredge.

 

The Dredge operating between 1940 and 1952, began a new era of gold mining on the Yankee Fork, a tributary of the Salmon River, and remains the only floating dredge in Idaho. The four story dredge dug into the river valley for a distance of six miles, recovering gold by washing and separating the rock, gravel and dirt. This operation made a tremendous mess of this valley by leaving miles of dredge tailings, but this is all part of Idaho history.

Everything 3/8 inch was retained, with larger pieces ejected.

The abandoned mining town of Custer once
had a population of over 600 residents.

Circle Tour - To Twin Falls, Sun Valley, Stanley & Challis

 

Home Sweet Home
It's really nice having a roof over our 5'er.

 

We took a two day, overnight, circle trip, Thursday (6/11) and Friday. First we headed southwest to the Twin Falls area. Friday we continued north through Sun Valley and into the Sawtooth Recreation Area and the mountain town of Stanley before turning back toward home through the Lost River Valley and right past Idaho's tallest Peak, Mt. Borah (el. 12,662).

 

Our first stop was a picnic lunch at Malad Gorge State Park. People pass by on the Interstate in a blink of an eye never suspecting this 250 foot deep gorge close by.

Our next stop was at Hagerman Fossil Beds National Monument. The major attraction here is the remains of over 200 species of plants and animals that have been found in the park, including complete skeletons of the Hagerman Horse, a zebra-like ancestor of today's horse. There are also deep wagon ruts left behind from the Oregon and Emigrant Wagon Trails.

The Perrine Bridge at Twin Falls, Idaho, is a truss arch four-lane bridge that carries US 93 over the Snake River Canyon. Perrine Bridge is 1,500 long and 486 feet above the Snake River. The bridge is a popular, and legal, BASE jumping site. We watched a number of jumpers dive over the edge. This section of the Snake River is also famous for the dirt ramp, still visible, where Evil Knievil unsuccessfully attempted to jump the Snake River in 1974. While in Twin Falls we also visited the Shoshone Falls and the Twin Falls, for which the town was named.

Our last stop was unplanned but very interesting. In October, 1983, a 7.3 earthquake formed a 21 mile long scarp near the base of Borah Peak. The movement of the rupture was up and down and is called a "high angle dip slip fault." This is clearly visible in the foreground of the picture with snow covered Borah Peak in the background. This earthquake dropped the valley 7 1/2 feet, raised the mountain over a foot and caused new springs and craters to develop. More than 400 billion gallons of water gushed from the ground. The quake did over $15,000,000 of damage to roads and the surrounding towns.

Craters of the Moon National Monument

Less than a 100 mile drive from Camas NWR lies the 750,000 acre national monument called Craters of the Moon. It received its name at the beginning of the 20th century when locals referred to the area as "craters of the moon." We now know better, as this was before Neil took his first step on the lunar surface.

There is a seven mile loop road that provides access to hiking trails, lava tube caves and viewpoints. The most recent eruption occurred a mere 2,000 years ago, and geologists believe that future events are likely.

The park was fully adorned in wildflowers during
our late May visit.
