Whether traveling to distant lands or discovering what's in our own backyards, geographers are always interested in not only where places are, not only what they look like, but why they look the way they do.  At the same time, geography also has to do with classifying and cataloguing the world. One way we do this is by placing a graticule, a grid of lines, over the globe so we have a standard way of answering the question, "Where are you?" The east-west lines, or lines of latitude, start from 0at the equator and go to 90at each of the poles. The north-south lines, known as lines of longitude, start from 0 at the Prime Meridian in Greenwich, England, and work their way around to 180 in the middle of the Pacific Ocean. Each degree is divided into 60 minutes, which are then divided into 60 seconds. See your textbook for more information on the graticule and latitude and longitude. There are thousands of points around the world known as confluences, where lines of latitude and longitude intersect as integers. For example, 41.0000N, 109.0000W has no minutes or seconds. An organization called the Degree Confluence Project is devoted to getting pictures of every point in the world (on land, at least!) at one of these points on the graticule. In this assignment, you will explore one of these confluences without ever leaving thecomfort of your home or library. Internet access and a printer are required to complete the assignment; please see me if this poses a problem for you. This assignment is due on Thursday, September 23 at the beginning of class. If you can't make it to class that day, either turn it in early or e-mail it to me. You will lose 5 points for each calendar day that it is late. Step 1: Where are we going? The first thing to do is to choose your confluence from the list in class. You can look at the map with the signup sheet for a general idea of where the confluences are. There's one or two available for most states, though some were too small to have any interesting confluences. Then, look on the attached map. Figure out where your confluence is. The graticule on the map includes every 10 degrees, so you'll probably need to estimate where yours falls. Mark your confluence with an X or a dot and label its latitude and longitude. Step 2: What do you think it looks like? Now that you've selected a confluence, what do you think the landscape looks like? Use your atlas to get a better idea of where exactly your confluence is (or try www.nationalatlas.gov). Do you think it is in a populated area or not? What do you think the climate is like in terms of temperature and precipitation (consult the climate map in your textbook)? What might the vegetation look like? Make a guess about the terrain: plains, hills, swamps, mountains, etc. Write down your answers before doing the rest of the exercise. Next, you'll need a topographic map of your confluence for a more detailed description. Go to www.topozone.com and look up your confluence as follows: 1) Select "View Maps" in the upper left-hand corner. 2) Scroll down until you get to the section labeled "Latitude/Longitude - Decimal Degrees." 3) Enter your coordinates. Remember to put in the negative amount for longitude (e.g., -109, not 109). 4) A new page will open with your confluence. In the frame on the left, underneath "Map Size," select "Large," and then click on "Update Map." 5) With the new, larger map, select "Print Copy" to the left. Print out a copy to turn in. You'll want to keep a second copy for yourself for a later assignment. Now, look at your topographic map and add to your description. What is the approximate altitude? Describe the topography of the area. If there are hills, are they steep? (Hint: How close together are the contour lines?) Are there any bodies of water: rivers, lakes, etc.? Any signs of human habitation? Is there anything you'd like to change about the predictions you made above? Now imagine that you're standing at the confluence point. Look to the north. What do you see? Are there hills or plains? Does the ground slope upwards or downwards? Are there any bodies of water? Any cities or towns? What do you see close by and in the distance? Repeat this for each of the other directions, and write down your answers before proceeding. Step 3: What does it actually look like? For the last step, you'll compare the predictions you made based on the maps to photographs of the actual location. Go to www.confluence.org, home of the Degree Confluence Project. From the menu bar on the left, underneath "confluences," choose "search." The first search option is "Confluence Quick Search." Input your latitude and longitude, being sure to choose N and W for the directions. When your confluence comes up, there will be a picture of the spot, along with a short description of how the person found it. On the left side of the page should be a few more photos, with at least one looking in each direction from the site. The bottom of the page tells you which photo is looking in each direction. How do the pictures of north, south, east, and west compare with what you expected to see? Did you correctly interpret the topographic map? Does the vegetation look like what you expected? Is there much evidence of human impact on the landscape? Step 4: What do I do now? You will turn in two parts for this assignment: the topographic map that you printed out, and the answers to the above questions, both your predictions and what the photographs actually show. I expect 1-2 pages (double-spaced, 12-point Times font, 1-inch margins), which is about 250-350 words. It is all right to use first person in your writing, but keep your writing style formal. Spelling and grammar do count, so please run your paper past a spell checker and another human being before turning it in. A sample assignment is attached so you can get an idea of what I'm looking for. This assignment is worth 125 points. You will be graded as follows: Correctly following procedure 5 points Reasonably correct map interpretation 40 points Well-written predictions for what your confluence looks like 40 points A well-written description of the actual confluence 40 points SAMPLE My confluence is at 41 N, 109 W. It is on the border between Wyoming and Colorado, just east of Utah (see attached map). I would expect to see a lot of mountains and not much in terms of habitation. The climate is probably pretty dry and cold in the winter. Therefore, we might expect to see sagebrush or other low, scrubby plants. After looking at the topographic map, I know the confluence's altitude is at about 8300 feet. Some of the land is flat while some is mountainous. The hills are probably fairly gentle. Because of the stream we might expect to see some trees. The topographic map shows that the confluence is just off a dirt road, in a little creek valley. To the east, we would expect to see hills sloping down from us. To the north should be first a downslope and then some steep hills in the background. To the west should be the stream in a valley. And to the south there should be a fairly flat plain. Except for the roads, there are no signs of life in any direction. Looking at the photos, it was greener than I expected. There are, indeed, sagebrush and trees. The land slopes up to the north before rising more steeply. The western view is obstructed by a tree, but it looks flat behind it. The land is also pretty flat to the south, with some hills in the distance. The ground to the east does go down at first, but then there's a hill to the right that I missed on the topographic map. The hills overall are rounded rather than steep, and there's no sign of population other than the dirt road. *,-/ 2 _ g > I MiUk48ntw*,!!!!Z#[#'ͣ h1N)H* h)h1N)h)5CJOJQJh1N)B*phh1N)5CJOJQJ h)5 h1N)5 h lq5jh1N)Uh) h1N)6jh1N)Uh1N)h1N)5CJ OJQJ0*+,.O P Q   HkdF$$Ifl40 ">N4 laf4$If$a$ ' IJKLija`Ekd/$$Ifl0,"p(4 la]:;vw' S !!!`^!f"[#$'d(/ =!"#$% FDd`Z  c 6Aglbovalib q{h t D nl q{h PNG  IHDR` sBITO0PLTE!!!111BBBRRRcccsssgbKGDH IDATx\b* Wm@wڙ*B>FWRP[|?ʈ?K;؏c/̛JyFqp!_ബ,}:2Yih&ﳻ&o206+OegHy, gR+2٥έUWʕ[dBQU+'Yވ,,pܿbgY;X՘zbςno:Q_@,P+Ѹ<쮳@W쐅$&z!ٌP6ӛ,|W%``YӦ-̭wx?`f@IN-:j׻}a7!n@hwE[_W_rɟjuW'шW_WtC12<Čo&?S#'l 6f``LWC!/)M'^_}cݦ3<\<&a;Pd? ]uxy*vGfB^fN$ޘKh0p,!L:xy 3{#m^uČW{##1xN*J_Xۦ<ɩ\iY$+X^ľ2T{>Nl!7){$ Qbe >9N4oǒ;AN(VRi}~v_Ι5'CVoG5|vS1@؜04&{WR=כcAs|OS+= !əAb@5w8w8Zf~|3wpN|NJ`X@` hMcT/>@GzcUZ ֳL#QyHo@}(-hψKiބIBbRJr 3ki_ 5SZI&u޵7x$|/tY8NxDPYahjޯۯyLzX8"Y޿)r]оｨ(Z}Bis +t9ܼ1'IvKX(D ^:ӟ鲀X>yC}ٱwDžn#i H+b@nNX f_#hbHksLRҞWkVl_&"[5#u8Ԑ=z.;&kW`3g O_ E< Xm&T&vkuJnH> l~2 E"*4])WEysպADȷ"n辟 Y* LK;:U̙TjoPe{ 紉]kEq>CBԮ_%YթO=P$/R%+ȊC95'5Ygy5&17D.ߡ !EV/aۗ˓I A_C{jZCHs=NްoR_g+-pVרkL[(\x!'ދT[sA!jQB}W$U7E*Cx˥1YF>ͭVVw;};f4%^ M< 1(W/+im(jzVC5k+}W٤]VaK yZ!6_I ؐesCHvf\M=egpOO^ !~Mgy!tT^# -G6B U@DY(dY:b.H< -ճ>"xa m=M6C\#!`JJ B:/g6!ndBqʄVfmY^'yk_h.ݬFsvIdHNv3 .PF$keDcQh4H Jno49+Z! ^4Zƫsl\ [RǢkjqu[aUH9b(MF]!!UYp~7B87&&铿f n,v@ GB|} @_cb:R&uIyǾ g)b?# gpqkSťL'iY($cjH@Hv (uр5풌^< OrF󤝃eﾴ *["N:T{wz'tZ\:+d{ 7ACx;Nc)EɊG}!*:l$?;$3HRU_$$;$P!qFai9vwe7 %3GPBQpo@ (2F7dT| Ayo@@~a") pfuE 6E k55e7h ,܀_; yb%&\_ãk;0^(vDݫ'n 3;^C/^v~Ē4X`hr\?9ڨQn1(8>s-O(TZ9;fkyrBf%&Tny1`}*v9='G~2~ #iZKܠL!x#PT fG2?03:G4xI0QrY4o`UQ^l($ed 2X( 6w18RV!&)ȨUw{>;+7`4F{ϛkqWGD/kSPg(:E}'ݬ䭖 J H{QB=!p%hi:IENDB`c$$If!vh5>5N#v>#vN:V l45>5N4f4 Dd`aP  c ,ADCPbN *-S9 4#>SQ151=9/N$@<VR%301?99D6"8$ ;;PQ-*I**K=1P7BO91N5J;PBN9L;LDRFJ<] A[HXRV GiLgOhNs%BR!LO-HL+OO%H\%N`#W`&Sk5NO1WR1ZZ4Sb?TL@VZJSOWWPh k { j } i' {/  % <ys,3"u532sDMlM"11IM.P.VZo/^i&]|1`{9^gB^c=\q;euGbeNd_JkkFfvTh]^g\Tgk`ig>orBs{:lJoZs_VoqRm~[oyT{lNyEuW{:lPuZtZkeSe{bhpmf{ogwyg{cxcrn\p~uoolWtyb|^mpkgoggtp}}zegnxvtſʻʹʹλͭεƭҽȽƵƸֽ`mIbKGDHIDATx{TMd(&   QڤxIj@ x9jHu!٤1YRlqTf9v/ړ?Y{n.gRK߯TnP2஽mcmd>kΤQ)eZc jd!`sve6X}/_ptT/TfFGlo6^&\K vx3EՎ.|:]Vnhm=UUZDM \(-%=GSm;O']{ϵ6r6 L!*rP0 jZ,K7&Ͽԁs!Dup 2"q?BeJ'% l܂z;::.h|;|6Йt!"H߿BeDE1{ A Οon&NUMz/DQŌd^?lC w8z4s~3POq4V Đ@5 f *a2 .Bw w;R;R #]atBʠ92Q{)̆+ ?ⲂÚ;:\aøPظ:S[ub1PA .3g<\a8qh/$ } 0:Shp%\1@$ N jz#+pyǎryB L&p:8N]J:6f7HPJ&fT}CfnzpPѾ|_q_M4t%͆*}M"QQ@G=잸}C}JeُsiI44?ۙ*_6)VwI&(QQQ%QT0P<uO~n.7 }Dp(TWtLx s,SU&ɠ)3"HDGe j4 Au̒ SȤ4`#AQǏGKAp'ʫtS@ݠBP) AW' W' 6ܤ#iIiIGH/ JMIF%ApLU']I vfIDbQ?%>"QQQ?Lл\U)"T_&VѹG~˽Jl maY+2-خgtFA{?pHwx^r(BjjH0*1@G?y_Mig&f%L؆?56DeR<c2/8 &x;L `/'3:BVZ?O8}fͷYyuiT<*6zG=K o*oT/B|`6fc/Y%4]"K( Fl@ v BqRLy;yz!= ξ !8JMV12֒ d|7Ae ŕJID;`*8))mWZѢr|NjV$Aot$7=$A'/a;{kd?G*Q zuLr i7ljii\,y`K6uB#}Œ$04K{zp+FDd8/(%/uĨ.mF#ȳvnN(SǓl/CqTv4=#‰$ 7>iM=+Hn=؛.@K=\+U$Ė'^nH MN8z"8\bd'ZU;&>v (=Ƌ ϋʄ7L %m'`)#A;+C=q>D0_{#bb|23F6h.R ҅htU+/}bq1B(E bN_wQ'M'OW&iLbEzh!7#=&ؙt9pD~O<%pb a[r>桐y>ۃLN~e*o- dm)BdY@NKۑ Cfp xy9yHRTݝ/vwO'=y{0$býROGL ڻlք?d!*({IP4|Oݔ'v{0oo u? @ \g\{ܮ&c:dq/+)LåCeS S})؃((@v uF%'ɝ~{ksrmbEXdX+GYgMHGV"퍢P5%&m(\{x 328 ~ BcPA!J XPn,+h4ۃ6YH+0Qy>Pd!"6>ݻ*<'@sRoZ5(fo*i9NU.aC($8Ž c30?12(wt&b72A28\$3%X7ە⚃IT(AV~/wwOL |}7I D1ᮠ|4;////L e5r)&RĔlJ-MG9/F䎛7nl 6}:,Ơ{~$" b1H7Kv4ՁYz^ooAJdfl:xN_Ie*XYX+a<1v˫7u\^j HdbĀL!ncfFG?mR{I^A)@7(TIfii-MݭV'h2H_|奿\0WrdA9DS#2F$zyyyx<<i`&#(%̖ZN*԰6),YL6"ЏHogyfJWiQX4L"Xy}$9oA9x$w9^9EEx)$b03Y^>Jua1WKSJwH/Wjc EEYdTqG軍g5"mlD $YnjjjbKKkKDӮ?ˍOfjlyMǓW̎G/WaƐ#H¢Bo9Icv#*(;5?+mSY4xeN u|6M Q-~dunV˔R) PxIQ0ȜFdc%qָۙmU¶lj)6/-el!wܹ5a5Ź^muK[ltA#kQˑq>EhItaQ`n"A P5kjP9nH'͋/~|껗ddpjQ&'.ՈH$K ܶۯ*ԚaiԫŪmMzJ!g^~lBvPVө!4)Y,Y_~z8|;n[[XгTr2.ڭzǴ| \@ަ#-EY;%YVDM) dI$6tx>pF,rtbGg|e֦$KOM}I PudHIV=0@gfkGCs_`;"ǂu^31hˈ4K/,.nd%"H.Eg^Tj_je2M\ŢSL)g`e1ϯܜ*O Ktlo<~0kd@D$ўYKz%*AEٙn΍.כpli kdѸ,]iU{qOTٷ/6'J4;&8 4@>*>#KvcXTI-OcITj^<}wf9אַYu:.pqze|<>'/;9B/.t&"Ojzk?JЩϾ۵rݠ–FY\\u~_V'';.Z.1%LJƭ2N\ fg?Cu9\k6wUD&s9շ__tN `6 j2=4Z}bdMr$e $bfJ!`5k5U>_Q9摙>-nfl6ǧF kլL|Zc^~`Wpdo@0<;k/Y:3 Ogtf >cY_b Y c80=B $GwNV3 "Eb5.U꧆YXɝa]c`g_TRf ?4%&F2Kjk2}A;8ɯL cbNYXO1 G&rs^c[?mj,uRW4552`UnLY)UsLT}q}rJcw=Ұp5KIKk\>8x:򧾝SpL^c/Ni}6|-z0ͯ9CkeƮZT]{ZTWfBI"nr|dZo֫Nscskmp4i]ךIvvSDʢU &ʝvxiP+M- DQ #E0Fܹ5gql_~gŹ2|ۮpK?4+)Y`0XG.yɑg̭: '&F_Z_-Jo훿ؚ( F Q̴:99߿x~>?<еM > n}pQVk;]~*(~A5+5L[7]>4sNwv##VX+,/,/Ϗ/]7KʏISJ} j:?kt&3331N) lq)+,.OPQ+@ć`@UnknownG: Times New Roman5Symbol3& : Arial5Gadget3Times"qh ۇFff [g[g!24dF2HP(?)2My confluence is at 41 N, 109 W Julie Cidell CSUS UserOh+'0 $ D P \ ht| My confluence is at 41 N, 109 WJulie Cidell Normal.dot CSUS User6Microsoft Office Word@H'@RW@.O, t@RW[՜.+,0 hp|  gG  My confluence is at 41 N, 109 W Title  !"#$%&'()*+,-./012456789:;<=?@ABCDEGHIJKLMPRoot Entry FDWRData /1Table3WordDocument*4SummaryInformation(>DocumentSummaryInformation8FCompObjq  FMicrosoft Office Word Document MSWordDocWord.Document.89q
