    Has anyone ever run across any kml overlay files of wilderness boundaries in the western US? If so, can you post a link?

    Thanks,
    Scott

    I've made a few myself, one wilderness area at a time. Here's how I did it:
    1) Pick your target area from here: http://www.blm.gov/ca/pa/wilderness/wa/wa_lister.html
    2) Click on the MAP link (brings up a PDF file).
    3) I use PDF snapshot tool to copy the section of the map I want onto the clipboard. If you don't have the PDF snapshot tool, you can use Windows print screen capability.
    4) Then use a paint program to paste the clipboard and crop the image down to size you want.
    5) Save that image in GIF format.
    6) In GE, select Add > Image Overlay
    7) Point to the GIF map image you saved.
    8) Resize and move the overlay image into place. This is challenging, and tends to leave things slightly offset of where you want them. But you'll get a pretty good idea where the boundaries are since they often skirt existing roads.
    9) You can play with the transparency to allow viewing the GE image as well as the overlay at the same time.

    I the overlay image does not get embedded into the KML file when you save to KML. So, be careful if you try to use the KML file on another computer, or move the GIF images later.

    You might also find this helpful since it does just what you want, but in browser rather than GE:
    http://www.geocommunicator.gov/blmMap/Map.jsp?MAP=LAND
    Under "Surface Management Agency" on the right, zoom in then select these:
    - BLM Wilderness Areas
    - BLM Wilderness Areas Labels
    There's a "Layer Opacity" slider and topo/aerial/base options at the bottom that help a lot.

    I figured out how to create a GE overlay that covers ALL the BLM wilderness areas.

    Here it is: http://www.HogWildRacing.com/ge/BLM_Winderness.kml

    Once you load that, you'll want to adjust the transparency so you can see through it. To do that, in your PLACES list, right-click on BLM Wilderness, and select PROPERTIES. Then adjust the slider to the transparency you like.

    I've figured it out in this thread in case you haven't gotten an accurate solution yet.

    It's pretty straight forward. To get a .kml file of western states you just download the entire .kmz file from wilderness.net. From that file you save individual wilderness boundaries as .kml using Google Earth. Additionally you can then convert those boundaries to any format such as .gpd or .gpx using GPSBabel.
    Hope that helps, Toni.
