A What specific type of feature is the Wah Wah Valley Hardpan? If the Wah Wah Valley Hardpan were to fill with water, how deep could the lake become before it overflows to the northeast along the jeep trail, near the red section number 27 located just above the northeast end of the hardpan in Fig. A14.3.1? Show your work. On Fig. 14.5, notice the curves that resemble topographic contours such as the one along which the points labeled X and are located. These curves are low, step- terraces formed? like terraces that go all around the valley, like bathtub rings. How do you think these On the aerial photo (Fig. 14.5) and topographic map Fig. A14.3.1), what evidence can you identify for a former deeper lake-an arm of Lake Bonneville-in Wah Wah Valley at locations X and Y? What was the elevation of the upper surface of that ancient lake? E On the topographic map, use a blue colored pencil to draw where the shoreline of ancient Lake Bonneville was when the lake filled to its highest elevation using your answer for part D. Then use the blue pencil to color in the area that used to be under water. F Studies by geologists of the Utah Geologic Survey and USGS indicate that ancient Lake Bonneville stabilized in elevation at least three times before present: 5100 ft. about 15,500 years ago, 4740 ft. about 14,500 years ago, and 4250 ft. about 10,500 years ago. 1. What is the age of the lake level that you identified in part D? 2. Modern Great Salt Lake has an elevation of about 4200 ft. and is 30 ft. deep. It occupies part of the large basin that w once filled by Lake Bonneville. How deep was Lake Bonneville at the current location of the Great Salt Lake when L Bonneville was at its highest level?
Explanation / Answer
1) The specific type of feature in the Wah Wah Valley Hardpan is Playa
2) Lake world overflow when the north east whwn it is 33 ft deep i.e, approximately 4470'-4437'=33'
3)These terraces are the ancient shore lines formed by the waves in the ancient lake.
4)They migrated basn word (towards playa) as the lake level fell.
6) 1. The age of the lake is 17,000 years
2.The depth of the lake is 930-940 feets
