The Nevada State Fish is Oncorhynchus henshawi henshawi (Lahontan cutthroat trout). It was once an important food source for the Paiute and Washoe tribes of Nevada and California. The fish evolved in the large endorheic Pleistocene Lake Lahonton that covered a portion of northeastern California and most of northwestern Nevada.

A black and white landscape photo of a fish painted on a black brick wall. The fish is in profile and faces to the left. It is about 25-30 feet long. The body is a quilt work of many geometric designs. A sign on the upper left of the wall reads: "Crystal Cove." Along the bottom of the wall it says, " Lahontan cutthroat trout back from extinction!"

Hiking Ancient Lakes part 3. This place is called "Ancient Lakes" and it's right by "The Gorge" amphitheater (WA people will know this place for its outdoor concerts). Ironically this system of coulees (canyon like flood channels) was formed by post-Ice Age glacial runoff, which in geological time isn't ancient at all-- it's like the day before yesterday. 3/8 #PNW #Washington #hiking #geology #iceage #getoutside #outdoors

View along the shore of one of the lakes mentioned in the post. The right hand side is a 45 degree angle debris pile, loose basaltic boulders and flakes, reddish in color. The lake is on the left. Around the edge of the water the rocks are covered in a white crusty mineral buildup which contracts intensely with the other rocks. The moody blue and coudy sky is reflected in the water.
Wide view of another lake with a spectacular cloud formation like a long tube running overhead into the distance. The lake has tiny ducks visible in the distance. The foreground is dried grass, basalt boulders, and gray-green rabbit (sage) brush.

Hiking Ancient Lakes part 2. The Columbia Gorge (which has the Columbia River running through it) is kind of unimaginably huge. The snow capped ridges in the distance are like 50km away and the river itself is beyond the nearer cliffs and lakes, but before the snowy ridges, hidden in a literal gorge some 500(?) meters below any of the ground you see here. 2/8

Wide view of a valley with the same brushy open vegetation, a small, still lake in it, and two cliffs beyond it. There is a gap between the cliffs through which one can see very distant snow covered ridges. Moody clouds swirl overhead.
Another view of the same valley with the lake more visible. The cliff on the right has an impressive pike of rubble at its foot forming a kind of ramp partway up it.

An #IceAge masterpiece: the oldest known representation of a bird.
The small carving (4.7cm) of a water bird was made from mammoth ivory some 40,000 years ago. It's thought to be a diver, cormorant, or duck.
Found in the Hohle Fels cave on the Swabian Jura.
On display at our branch museum Urgeschichtliches Museum Blaubeuren.

The photograph depicts a small bird figurine with an extended neck, a pointed beak, and wings held close to its body. The figurine is well-preserved, although its tail is broken and its surface shows signs of weathering.
