Mono Lake - Element 16

Skill 1: Map Use
Element 16: Lakeshore Mapping

Materials:

Drafting tape

            5  11"x 17" clear film overlays

            Green, orange, brown, purple, red marker pens

            1985   11”x 17” section of the Habitat map

            1999   11”x 17” section of the Habitat map

            Table “Mono Lake Level 1850-1998”

            Geographic Summary, Lake Level Issue, 1941 to 1994 and 1994 to present

Exercise:

Note: This exercise can be worked in groups of two with each person preparing an overlay or coloring a NWI map section.

   1.     Use the 1985 Habitat 11"x 17" map

   2.     Use a clear film, 11"x 17", overlay

   3. Tape clear film overlay on top of 1985 Habitat map.  Tape top edge.

   4.     Use Green pen to mark “corner ticks” on the overlay, one at each corner of the study site.

         5.       Trace the Mono Lake shoreline in Green.

   6.     At the bottom of the overlay (in green) draw a short horizontal line and label beside it “1985 Shoreline.”

         7.       Remove the “1983 Shoreline” overlay.

         8.      Use another 11"x 17" clear film overlay.

  9.      Tape the clear film overlay on top of the 1999 Habitat map.

10.      Use Orange pen to mark “corner ticks” on the overlay, one at each corner of the study site.

      11.       Trace the Mono Lake shoreline in Orange.

12.      At the bottom of the overlay (in orange), draw a short horizontal line and label beside it “1999 Shoreline”.

      13.       Remove “1999 Shoreline” overlay.

14.       Tape the third clear film overlay over the 1:24,000 scale topographic map.

15.        Use Brown pen to mark “corner ticks” on the overlay, one at each corner of the study site.

16.       Draw a lakeshore that approximates the current day shoreline as found in the Geographic Summary.            

Hint:             Remember that the contour interval is not the same for all four quadrants of the 1:24,000 topographic map.

      17.        Draw a brown line ½ inch at the bottom of the overlay and label it  “2000 Shoreline”.

      18.        Remove the “2000 Shoreline” overlay.

      19.        Tape another clear film overlay over the 1:24,000 topographic map.

20.        Use Purple pen to mark “corner ticks” on the overlay, one at each corner of the study site.

21.       Draw a lakeshore that approximates the highest shoreline ever recorded for Mono Lake, a found in the Table of Mono Lake Level 1850-1998.

22.       Draw a purple line ½ inch long at the bottom of the overlay and label it “Highest Recorded Shoreline”.

23.       Remove the “Highest Recorded Shoreline” overlay.

24.       Tape another clear film overlay over the 1:24,000 scale topographic map.

25.        Use Red pen to mark “corner ticks” on the overlay, one at each corner of the study site.

26.       Draw a lakeshore line that will approximate the proposed stabilized shoreline that approximates the proposed stabilized shoreline as found in the Geographic Summary, Lake Level Issue, 1994 to present.

27.       Draw a red line ½ inch long at the bottom of the overlay and label it “Proposed Shoreline”.
