Thus, both halves will look entirely different than they do now. 6. 7. Estimate the level of the water table in several sinkhole lakes around the map, as well as the level of the swampy ground in the south. From this, can you tell what the hydraulic gradient of the underground water is? That is, can you determine a direction of flow? (a) north; (b) west; (c) southeast; (d) east; (e) south; (f) northeast; (g) northwest. Why does the stream flowing into Double Sink (near Turnhole Ferry) end so abruptly there? (a) it is in intermittent stream that loses its water downstream due to evaporation; (b) the land tums uphill, preventing the water from climbing upward; (c) the area is underlain by extremely porous sandstone; (d) they flow into a sinkhole that connects to an underground stream; (e) the water volume is insufficient to sustain flow. Examine the topography in the east-central part of the map. A number of valleys such as Cedar Spring Valley, Woolsey Hollow, and Owens Valley resemble stream cut valleys, but there are no streams flowing in them. What might cause this? (a) the area is arid, and the valleys are occupied by intermittent streams that only flow during flash floods; (b) the sanstone bedrock absorbs the water faster than it can accumulate is the streams; (c) the stram gradients are so steep that the water flows into the main river faster than it can accumulate in the stream valleys; (d) the are solution valleys that connect to underground caves with underground rivers. Where is the water table in this area, compared to the water table in the Interlachen, Florida, area? (a) they are similar; (b) it is deeper, (c) it is shallower; (d) it varies in both areas. What is Tumhole Bend on Green River? (a) water gap; (b) incised meander; (c) grand canyon; (d) stream terrace; (e) braided stream. Examine the river (Green River) in the northern part of the map. In the stream erosion cycle, is this area in (a) youth; (b) maturity, or (c) old age? Is the Mammoth Cave area in the stage of (a) youth; (b) maturity, or (c) old age, of the karst erosion cycle? Re-examine the previous map. Is the interlachen area in the stage of (a) youth, (b) maturity, or (c) old age, of the karst erosion cycle.

A pair of sink-holes straddles the boundary between Sections 5 and 8 about 1.5 miles north of the east- west highway (at Number 1) that crosses the central part of the map area. What is the approximate elevation (in feet above sea level) of the bottoms of these two sinks? (a) 55; (b) 130; (c) 300; (d) 100; (e) 90 In the same general area, an unnamed lake occupies a sink-hole in the NE % of Sec. 7, and another occurs in the SW % of Sec. 4. Assuming the water surface of these two lakes lies 5 feet below the elevation of the contour nearest the lake shores, what is the elevation of these two lakes? Sec. 4 lake? (a) 90'; (b) 85'; (c) 80' (d) 75' (e) 70'; (f) 65'; (g) 60' Sec. 7 lake? (a) 90'; (b) 85'; (c) 80' (d) 75' (e) 70'; (f) 65'; (g) 60' Why are the two sinks in Sections 5 and 8 (Number 1) dry (that is, they contain no lakes) when Section 7 lake and Section 4 lake both lie less than a mile away? (a) they are underlain by a porous sand that can hold no water; (b) they have been drained for use as a landfill; (c) the bottom is filled with sediment to a level above the water table; (d) an impermeable clay "plug" underground retards the flow of water into the sinkhole. The blue "grass" symbol in the south (lower) part of the map indicates swampy conditions. What accounts for the preponderance of near-surface water there? (a) the water table is near the surface; (b) the area is underlain by impermeable shale; (c) it is a coastal swamp covered by sea water at high tide; (d) the land is so fat the surface drainage is retarded; (e) the area is infested with beavers that have constructed many beaver dams. Generally speaking, the northern half of the area has greater relief than the southern half of the map area. The northern half has no streams, whereas the southern half has Gun Creek Cabbage Creek, and Little Cabbage Creek. Assuming that these two areas reflect different stages in the evolution of karst topography, will the northern half become or like the southem half during the passage of time, or vice-versa? (a) because of global warming, the rise in sea level will cause the water table to rise also. Thus, the northern half will come to resemble the southern half; (b) there will be no relative change. Conditions in both halves will remain much the same; (c) s the land rises by isostasy. The water table will drop, creating deep sinkholes in the Page 3 of 13 Sodus Quadrangle, New York 2. 3. 4. 5. 6. 7. 1. 2- What geologic name is applied to these glacial features, such as Brantling Hill? (a) esker; (b) roches moutinee (c) arte; (d) drumlin; (e) kame terrace; (f) kettle; (g) varve. What type of material are they probably composed of? (a) glacial outwash; (b) glacial till (c) ice-contact stratified drift; (d) glacial lake deposits; (e) turbidites; (f) evaporate deposits. 3. These landforms are produced by: (a) meltwater streams flowing beneath the surface near the terminus of a wasting glacier, (b) by ice flowing over a bedrock surface, producing a rounded, shiny knob that is heavily striated; (c) by two adjacent glaciers deepening and widening a glacial valley to produce a knife-like ridge; (d) by a re-advancing glacier that plows over till deposits left behind from a previous retreat phase; (e) as crevasse fill of sand and gravel in a wasting glacier; (f) from ice blocks that settle into wasting glacial deposits; (g) in glacial lake deposits. Passadumkeag Quadrangle, Maine The main use of these features is: (a) as an important sand and gravel source; (b) as a glacial streamline feature that indicates the direction of glacial flow; (c) as an indication of the glacial budget; (d) to show the position of the snow (fim) line.
