This page incorporates the 2003 and 2013 LiDAR surveys,
showing the results of the landslide of 2006.

For those with GIS who have trouble with filegeodatabase (.gdb) files,
we have posted geotiff files of a limited area.
The the shaded-relief (grayscale
topographic image) can be seen in any picture viewer, and will land in the
right place in any GIS program. The elevation file is similar, but its 16-bit
data will be a problem in some image viewers. The original data is floating
point numbers, but it has been scaled to integer inches (be careful) for
portability. The actual color picture is not a geotiff, but is
a pixel-for-pixel match to the others.
