Thousand Springs Scenic Trail

This area of Idaho is known as Magic Valley, consisting of several counties in south central Idaho.  During the first decade of the 20th century two dams and a series of irrigation canals were constructed on the Snake River, resulting in the area being “magically” transformed from a nearly uninhabitable area into some of the most productive farmland in the Northwest.

As we left the Craters of the Moon, we decided to drive a little bit out of our way on our return trip and take the Thousand Trails Scenic Byway, south of the Snake River.

The Byway starts just north of the river with a dramatic drop into the canyon 

crosses the river, and follows along the fertile farmland. There were several side trips that we’ll save for another time.  As we continued along the river, we began to notice numerous waterfalls along the cliffs on the opposite bank.   The falls originate from underground vents carrying water from the Lost Rivers far to the north, surfacing here in the “Thousand Springs” area.

Spanning the river between Twin Falls and  Jerome is the Perrine Bridge, 1500 feet long and situated 486 feet above the Snake River.

The gorge’s claim to fame is Evel Knievel’s attempt to jump the gorge just east of this bridge.  Here’s a short YouTube video of the event.

 

You can still see the jump site mound from the bridge.

The bridge itself has become famous for a different type of jump, BASE (acronym that stands for four categories of fixed objects from which one can jump: buildings, antennae, spans (bridge) and earth (cliff) jumps.  The Perrine Bridge is the only bridge in the U.S. from which you can jump legally without a permit, and has become one of the most popular sites for parachute BASE jumps.  In fact, while we were at the Visitor Center, several young men were preparing their parachutes for a jump from the bridge.  They told us it would be 20 minutes to a half hour before the jump, so we thought we had plenty of time to drive across town to see the Shoshone Falls.  Unfortunately, rush hour traffic prevented us from getting back in time to view the jumps.  Here is a short video however, from a similar jump occasion.

Our last stop of the day was Shoshone Falls, also known as “Niagara of the West.”  Even though it is late in the summer, and the flow of water over the falls is low compared to spring levels from snow melt, it was still very impressive.   

Over eleven hours after leaving home, our day was over and we were very tired, but what a rewarding day!

A Trip to the Moon – Craters of the Moon, Idaho

Craters of the Moon National Monument is a volcanic lava flow in south central Idaho.   This park with its lava formations covers 1117 square miles, the size of the state of Delaware.  The lava fields and formations are so large and dark, they can be seen by space satellites. The monument has 3 major lava fields, 60 miles wide, which are the largest and best preserved examples in the 48 contiguous United States.  The rift that opened the Earth’s surface a million years ago is 62 miles long.  The lava deposits are as deep as 10,000 feet, the deepest known on earth.

The park is aptly named as Apollo 14 astronauts spent several days here in 1969 preparing for a voyage to the moon’s craters.  Truly, you feel as if you’ve stepped into a foreign landscape, one sharply defined at it’s edges. A 7 mile loop runs through the park, with several stops.Although some were closed for construction, we still were able to see a lot of the area.  Our visit started in the Visitor Center with a video on Robert Limbert, one of the early explorers who gave the area its name.  Limbert, his dog, and a friend spent 17 laborious days crossing the lava beds in 1918, resulting in publicity that gained national attention.  For more on Limbert, read this short history segment.

First stop on the loop is a short quarter mile trail crossing one of the youngest flows to monoliths-crater fragments rafted here by lava flows.  Several formations of lava are prominent in the park, composed of the following

a’a (Hawaiian for “stony, rough lava” or “blaze, burn”) lava flows quickly, causing cracks to be formed on the surface, resulting in jagged razor sharp slices of stone.

The second type is Pahoehoe (Hawaiian for “to paddle” (probably from the swirls on its surface)a type of lava flow which spreads in sheets.   The surface is a glassy layer which has been dragged into ropy folds by the movement of the hot lava below it.

It’s hard to believe that these monoliths floated here in the flow of lava.  Scientist estimate all this activity happened 2,000 to 15,000 years ago.

Our next stop was at the Spatter Cones, which are small craters.

At an outside temperature approaching 100 degrees, we were amazed to see snow still at the bottom of one of these craters.

Climbing the steep path nearby, we gazed down into one of the larger craters.

An amazingly hardy little tree stands bravely at the bottom.

Our last stop on the loop was near the “caves” formed of lava tube channels.  As hot fluid lava streams begin to cool from the top, a ceiling is formed.  Then lava drips down the sides making an enclosed tube cave.  These caves can be 1,000 feet long. 

These shots were taken along the 1/2 mile trail to the caves:

 

 

There are 4 caves near each other.  We chose Indian Cave at 800 feet long because it’s ceiling has collapsed in several places, letting in enough light for you to explore without the use of a flashlight.  Although much of the stone in these pictures appear white, that is an optical illusion due to the sharp contrast of light and dark, and the use of a flash once inside the tube. The stone is actually shades of dark gray to black.

Several metal steps lead down into the tube opening.

Light shines through the collapsed ceiling in several places.      

Toward the end, there is a huge pile of debris to climb over

and the final exit is a climb through a tiny hole.

Once out, you make your way over the rough lava back to the paved trail.  This is one of the few places in the park where you are permitted to walk on the lava.

 

We marveled at this crack, so defined along a cubic break.      Craters of the Moon… a fascinating, otherworldly experience.

 "A weird and scenic landscape peculiar to itself," stated President Calvin Coolidge as he dedicated the new memorial.  A pioneer traveling the Oregon Trail in the 1850s looked at the blackened earth and described the land before him as "Devil's Vomit." An explorer recalled in his journal that this land is "the strangest 75 square miles on the North America continent."  And Jerald R. Lovell, a researcher and author,  remarked (this part of Idaho is) "Iceland and Hawaii all wrapped up in one."
