Happy Thanksgiving!
Cailin, a good friend and member of the 705 Backcountry Ski Patrol, created a Google Earth KMZ file for the Mores Creek Summit area.
Below a description of the individual layers:
- slope - <25 degrees not shown, 25-35 yellow, >35 degrees red (as in "green, yellow and red light" terrain).
- smooth slope - same as above, with the underlying elevation data smoothed beforehand. It is worth comparing the two.
- contour - 10m contour intervals for the area
- all tracks - Overview map of Mores Creek area, previously published here.
- convexities - Roll overs appear as grey areas
- common routes - these are individual tracks from the above map, skin tracks shown in purple and ski lines in blue. Right click -> "show elevation profile" to explore length, steepness etc...
Note that you can overlay multiple layers at a time, as well as adjusting the transparency of each layer. There are definitely some limitations (especially small steep areas and convexities too "fine" for the data to see), and obviously no substitute for field observations and safe travel.
Below few examples of the use of this utility for the lower Pilot and Lamar ridges:
 |
| 10 meter contours |
 |
| Slopes with 25-35 Deg (Yellow) and above 35 Deg Slopes (Red) |
 |
| Slopes with North (red) and East (Yellow) aspects |
Comments and feedback are welcome. It will allow us to further develop and enhance this layers for Google Earth, and incorporate other areas such as Banner Summit, Big Creek Summit, as well as Brundage/Bogus Ski Resorts "side country".

Great stuff! I would like to see Copper included in the list.
