GEOGRAPHY – ELEVATION PROFILE – Due 2/17
DON’T let someone else do your work. It’s Okay to coach but don’t steal your buddy’s education. It’s no service to them to figure it out for them… because they need to know how to do this. If you’re lost, or just want more practice, stay for after class coaching, it’s for you!!
Symbols for USGS maps are found at: http://erg.usgs.gov/isb/pubs/booklets/symbols/
Examine the topographic map. Call it up on GOOGLE EARTH. Find the 4800 ft a.s.l. (feet above sea level) contour and darken it and Find the 4400 ft a.s.l. contour and darken it.
· What is the “contour interval” between the solid, dark contour lines, meaning, what is the difference in elevation between the major, dark brown, contour lines? _____
· What is the contour interval between the dotted lines near Rice-Eccles stadium? _____
· Why are there dotted lines some places and not others? ____
· What is the elevation of the ground between Orson Spencer Hall and the library?
· Why is the library shown in purple and most of Orson Spencer Hall shown in black?
· Why is Mt Olivet cemetery shown in green?
Now… draw a profile
of the topography along the line I’ve put on your map.
First: take (or make) the paper strip. (In the field you’d tear it from a field notebook… or use the notebook page as the “strip.” Lay the strip right along the line of your profile. MARK and label the ends of the profile. And add “E” for east and W for west.
Second: mark every single DARK contour line-crossing along your strip of paper with your own symbol… I use my brown pencil and make a half inch vertical line on my “strip.” Using another color, mark cultural features, on the “strip” with a little label. I usually use blue for streams, black for roads and culture such as fire stations or buildings I know, such as Rice Eccles.
Third: label each contour tick on your strip of paper with the elevation of the contour. And decide whether you have sufficient data … big gaps. If big gaps… use little tics for LIGHT brown lines.
Fourth: take your strip of paper, and put it along the line below the graph below. Add “A” and “A’” and add East and West.
Fifth: Look at your data, look at your worksheet. Add a sensible scale for elevations to the vertical scale on your worksheet.
Sixth: transfer the contour ticks of your strip of paper to the line below the graph and label the transferred marks. Also transfer markings you made for features. REPEAT!! TRANSFER ALL THE INFORMATION FROM YOUR STRIP OF PAPER TO THE LOWEST LINE ON THE WORKSHEET, there’s a big arrow pointing to it. Don’t skip this step to success..
Seventh: Project each of your ticks as dots onto the lines of elevation of the graph. Connect the dots and, congratulations, you have drawn a profile. Label at least 5 features. Check your work against Google MAPS profile tool. LINK to HeyWhatsThat Path Profiler
Eighth… Ask yourself, from your own experience, what is steep, what is flat? Note how the contours depict this. Have you ridden a bicycle across this area? If you know that the Wasatch fault is in this vicinity and at the bottom of the break in slope, where would it be on your profile? Label it on your profile. DO NOT SPOIL THIS MOMENT OF DISCOVERY FOR OTHERS!
YOUR ELEVATION PROFILE Your Name:
AND STAPLE YOUR SLIP OF CARDBOARD – PAPER onto this sheet
The line the arrow points to is HUGELY important.
It’s where you transfer your data to …
From the “piece of cardboard”
As much info as possible gets transferred. Don’t miss this step. Many and Earth scientist has lost the little slip of paper and been grateful for data transferred to the line above.
CLUE: that line is only for data… it’s not part of your profile.
