6-3: Again, the locating is up to you. BACK

6-4: Plymouth is about midway along Plymouth Bay which lies about 60 km (40 miles) south of central Boston. There, the good ship Mayflower landed its Pilgrims in 1620. Gloucester is just within the image in the right center top. BACK

6-5: Two other possibilities come to mind. This is the kind of pattern that is typical of a garbage boat that dumps wastes out in the open sea. Also, it resembles a spreading contrail from a high altitude aircraft and may have been produced by a plane in a holding pattern awaiting a Boston landing. BACK

6-6: State College, where the writer spent a wonderful year in graduate school, is the elongate blue patch just west of a plunging anticline whose nose points south. Camp David is located in a remote area of South Mountain. It was there, in 1974, that the writer was stopped outside the gate by a Secret Service agent, while I was studying a false color Landsat enlargement of that part of Maryland. When asked by him why the picture was so red, I (foolishly) replied. "Well, it's the Communist version". Had to talk my way out of jail. BACK

6-7: The Delmarva Peninsula is left of the right center margin. The Shenandoah Valley includes the light toned area in the center of the image. One must look hard for Pittsburgh. Look left of the upper center; note two rivers - the Allegheny and the Monongahela - that meet at Pittsburgh to form the Ohio. The state of Ohio lies above the Ohio River in the upper left. Parts of these states are included in the image: Pennsylvania; Delaware; New Jersey; Maryland; Virginia; West Virginia; North Carolina; Kentucky; and Ohio. BACK

6-8: From the redness in the greater Chicago area and the dominance of fallow fields in Illinois beyond, this is likely a Fall image. In fact, it was taken in October. Those "clouds" are smoke coming from the steel and other industrial plants in that area. BACK

6-9: The towns are Boulder, Longmont, Fort Collins, and Greeley. They are very hard to find in the summer image since they are either enriched with trees (e.g., Boulder) or are surrounded by nearby farmland. The brown color in the mountains results from the high percentage of evergreens in the foliage. Snow is everywhere including the highest elevations in the Rockies. The lakes are frozen and snow-covered. Both the snow and the low Sun angle emphasize drainage. BACK

6-10: Unless you are a geologist, or remember this from a college course in Geology, you probably could not answer the question. However, the main ideas are briefly put together in the text. Still, you may not have made the connection. Here's the scoop: Goosenecks are a local term for entrenched meanders. The river meanders existed before the whole Colorado Plateau underwent a general uplift during and after the mountain-building episodes that led to the present Rocky Mountains. With this uplift, the stream gradient (related to height of river above sealevel and to its rate of descent) increased, giving the water more erosive power. It thus could downcut into the rising Plateau rapidly, preserving its earlier course as the now steep-walled meanders. BACK

6-11: 4 = Theodore Roosevelt Lake; 5 = Los Angeles; 6 = Death Valley; 7 = Grand Canyon; 8 = Mojave Desert; 9 = Junction of Gila and Colorado Rivers; 10 = the Pinacate volcanic field in Mexico (a tough one, not always on maps). The Mojave boundary fault is the famed San Andreas fault. BACK

6-12: Your call. BACK
