Bonneville Cutthroat The 13 different Cutthroat subspecies have apparently evolved in isolation from each other. Natural barriers segregated them from other populations long enough for them to assume |
| unique characteristics. Some subspecies Such as the Bonneville Cutthroat, were isolated in giant ice-age lakes. Looking east to the distant mountains from Great Basin National Park, one would not imagine that thousands of years ago the Snake Valley was filled by an inland sea called Lake Bonneville. Lake Bonneville existed from about 32 to 14 thousand years ago. It occupied a low, closed depression in the eastern Great Basin and at its largest extent covered about 20,000 square miles of western Utah and smaller portions of eastern Nevada and southern Idaho. The water which formed this lake came from streams, many of which originated as melt water from glaciers in the surrounding mountains. Thus within this Pleistocene lake the Bonneville, cutthroat trout (Oncorhynchus clarki Utah) were isolated from other trout populations over the last 25,000 years. Towards the end of the Pleistocene era, the climate became drier, glaciers melted, many rivers and streams ceased their flow, and the evaporation of lakes exceeded the inflow. The lakes dried throughout the Great Basin, and the net effect was to produce the present moist high mountain islands surrounded by seas of low desert. As Lake Bonneville dried up, populations |

of the indigenous cutthroats sought refuge in more favorable habitats within the cool, clear, high mountain streams. Bonneville cutthroats flourished in this new-found habitat and were once well distributed in all major streams on the east side of what is now Great Basin National Park. The process of change within individual isolated |
| populations is still going on today. An example is the Bear Lake Cutthroat pictured above has a unique coloration. Bear Lake Cutthroat have a beautiful aqua blue cast on their backs and heads, not unlike the color of Bear Lake, hence the common moniker of "bluenose" trout. |

| Quotes from Will
Rodgers: -Good judgment comes from experience, and a lot of that comes from bad judgment. -Lettin' the cat outta the bag is a whole lot easier 'n puttin' it back in. -If you get to thinkin' you're a person of some influence, try orderin' somebody else's dog around. -After eating an entire bull, a mountain lion felt so good he started roaring. He kept it up until a hunter came along and shot him... The moral: When you're full of bull, keep your mouth shut. -There's two theories to arguin' with a woman. Neither one works. -If you find yourself in a hole, the first thing to do is stop diggin'. -When you give a lesson in meanness to a critter or a person, don't be surprised if they learn their lesson. -When you're throwin' your weight around, be ready to have it thrown around by somebody else.
