Back-rotated trees in the distance.  This is how the brown house as seen the photos below as seen after the demolition.
This is likely a pressure ridge due to a more resistant feature below the slide plane. A sag pond collects water, a typical feature in landslide terrain.

The brown house has moved very little since last summer. According to one account, it has only moved a few feet over the entire winter. Compare this photo with others above. In an apparent effort to prevent people from entering into the lower part of the landslide area, workers spread debris across the road to make access difficult. 
The rotated house has moved only slightly down slope this past winter. only the roof can be seen in this photo. Trees can be seen falling at odd angles in this photograph. Here's a tip, if you see a large number of trees falling in the same directions, it is a good bet that the area might in a landslide area.

This photo shows the amount that the rotated house has traveled down the hill. The house is barely visible around the tree and is still accelerating down the hill. rotatedhouse_03-00.jpg (124027 bytes) Where the rotated house was in the last set of photos. The brown house is still being torn apart by the landslide.  lower_03-00.jpg (116026 bytes)

The two photos to the right show differential movement in the slide area. Notice that the half of the house downslope is moving faster that the rest. This has caused the house to be split into two (sans roof) exposing the contents of the house downslope in the right-most photo.

This is the original house that rotated that has served as a marker to as how much the area has moved in this portion of the slide. This house was on the right side of the street on which this photo was taken.
This is the brown house that was right next to the rotated house, in the first photo on this page. Notice the difference in rates of movement between this house, and the beige on down the hill, which were right next to each other.

Photos taken in mid-June, 1999 by an unnamed person (they should have not been in the forbidden zone).

This is a close-up of the garage seen in the original photo page.
These are the two houses that I have photographed and posted here before. The beige house has move significantly down the hill.
A new view of the large scarp. Look at past photos to compare widths.
