Our new black tricolor. I went all the way to Twin Falls, Idaho (~400 miles) to pick him up at the animal shelter there! But so far he's fitting in fine. "Frank" is the shelter's name, but we didn't have any better ideas so we're keeping it.
Snake River, in the Snake River Gorge, Idaho. The original installation dates to 1907--as you might gather from the orange crane, its capacity is being upgraded at present. The spray in the foreground is from the falls themselves.
Carrying U.S. 93 across the Snake River Gorge from Twin Falls, Idaho. Looking north from Twin Falls. The insets show (left) a view of the bridge from the north and upstream side, looking back toward Twin Falls; and (right, below) a view under the bridge from the north side looking south. This inset is positioned at that viewpoint. Perrine was a prominent early settler and promoter. Downstream is to the left.
Twin Falls, Idaho. Looking downstream (west) from near the southern end of the I.G. Perrine (US Highway 93) bridge. I thought the golf course nestled improbably amongst the craggy outcrops was an interesting touch! As I've noted elsewhere, this canyon was scoured and deepened about 18K years ago by the so-called Bonneville Flood, when Pleistocene Lake Bonneville overtopped a drainage divide into the Snake's drainage basin. The resulting rapid downcutting led to the natural equivalent of a dam failure. Lake Bonneville covered much of western Utah (the Great Salt Lake is a highly shrunken remnant), and it suddenly lost the top few hundred feet of water depth as a result of the flood. Geomorphological evidence indicates that at peak flow this canyon was filled brim to brim.
On the Snake River in southern Idaho. A gray day, but the falls are in fine form! Later in the season they often go dry because of upstream diversions for irrigation. Some water is also diverted for hydropower, in an installation off the pic to the left (inset).
Shoshone Falls lies in the spectacular Snake River Gorge, which was scoured and deepened around 18K years ago by the so-called Bonneville Flood. Lake Bonneville, an enormous Pleistocene lake covering much of western Utah, overtopped Red Rock Pass in southern Idaho and started spilling into the Snake drainage. The material where the overflow occurred was loose ("unconsolidated", in the jargon) and started eroding very quickly, to yield the natural equivalent of a dam failure. The top few hundred feet of Lake Bonneville spilled out this way in a matter of a few weeks! Geomorphological evidence indicates that at peak flow the gorge was completely filled brim to brim.
