I have posted a KMZ of the Alaska Game Management Units at http://geoapt.com/alaska_gmu. This is a vector file. After loading in to Google Earth, clicking on a unit will display its name.
Please note the limitations of this information and read the first few sections of the Metadata.
For those interested, Googe maps/earth use a modified Mercator projection. The GMU data was obtained from the State and transformed into the proper projection for overlay.
