  1. Root systems

    Snapshot Title: Root systems
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    Denser vegetation and more tree growth may in part be responsible for the decreased amount of landslide activity on this part of the bluff.



  2. Less landslide activity

    Snapshot Title: Less landslide activity
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    This area seems to have experienced less landslide activity recently. The slope is gentler here, which may be increasing the safety factor. Vegetation may also be contributing to the slope's stability...



  3. Snow

    Snapshot Title: Snow
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    Snow melt can potentially increase pore water pressure and cause future landslides.



  4. Lower Scarps

    Snapshot Title: Lower Scarps
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    Not only is the top of the bluff sliding, but in some cases the debris piles at the bottom of the bluff become steep enough to experience their own minor slides.



  5. Uprooted trees

    Snapshot Title: Uprooted trees
    Taken by: eos101

    Image Owner: eos101



    Description:

    These trees may have been uprooted with the landslide activity.



  6. Epic struggle

    Snapshot Title: Epic struggle
    Taken by: eos101

    Image Owner: eos101



    Description:

    Walking on mud flats takes practice, apparently.



  7. Scarp

    Snapshot Title: Scarp
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    This scarp and the mass of material beneath it are evidence of landslide activity. The movement appears to have been a debris slide (the mass is relatively intact). The vegetation on top of it was pro...



  8. Pile of debris at bottom of bank

    Snapshot Title: Pile of debris at bottom of bank
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    Here the accumulation of debris that slid down the bluff is visible. Vegetation is still growing here.



  9. Land shifting

    Snapshot Title: Land shifting
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    The angle of the trees on the bluff points to a slow movement of the land down the slope.



  10. Evidence of landslide

    Snapshot Title: Evidence of landslide
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    The accumulation of material beneath this long scarp seems indicative of a debris slide (or possibly fall). The vegetation here seems to have been growing on the mass before the landslide occurred; so...



  11. Slow-moving debris slide

    Snapshot Title: Slow-moving debris slide
    Taken by: eos101

    Image: Freeport Landslides (West)
    Image Owner: eos101



    Description:

    It appears that this patch of the bluff has been slowly subsiding for some time. During a storm, it may slide down the bank completely.



  12. Couldn't stand still

    Snapshot Title: Couldn't stand still
    Taken by: eos101

    Image Owner: eos101



    Description:

    We didn't realize we were in the shot.



  13. Freeport 11

    Snapshot Title: Freeport 11
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    Trees leaning towards the mud flats due to the movement of land on the bluffs. These trees and creeped onto a near 90 degree angle rock face, which clearly would not be able to support the trees and w...



  14. Freeport 10

    Snapshot Title: Freeport 10
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    An example of a more recent slide, these still-alive trees have fallen over on a steep slope of the bluff, giving clear evidence of a landslide that took place recently.



  15. Freeport 9

    Snapshot Title: Freeport 9
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    A large collection of trees leaning down the slope due to the movement of land. These trees grow on the steeper part of the bluffs, and clearly experience mass wasting on this land.



  16. Freeport 8

    Snapshot Title: Freeport 8
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    More evidence of the instability of this slope, where large masses of trees slide beyond the slope of the bluff and land onto the base of the mud flats. The type of movement along this bluff would mos...



  17. Freeport 7

    Snapshot Title: Freeport 7
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    Clear movment of a large, living tree down the hillslope, until this point where much of its root system is visible above ground and is held in place by very little of its base.



  18. Freeport 6

    Snapshot Title: Freeport 6
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    The creep of land over the dense clay bottom shows the importance of groundwater on this bluff. The land above the mudflats is dirt that passes water much more easily than the clay shown below the cre...



  19. Freeport 5

    Snapshot Title: Freeport 5
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    The remains of large, weathered trees shows both a history of past landslides but also that many of these were large enough to uproot trees of this size.



  20. Freeport 4

    Snapshot Title: Freeport 4
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    The angle of dead trees leaning towards the water shows the movement of land down the bluff over time.



  21. Freeport 3

    Snapshot Title: Freeport 3
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    Fallen trees below the scarp line shows the gravity of movement and slides, to the extent in which fully rooted trees have fallen over on the bluff.



  22. Freeport 2

    Snapshot Title: Freeport 2
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    Much more weathered scarps show that this bluff has a history of slides in the past.



  23. Freeport 1

    Snapshot Title: Freeport 1
    Taken by: eos101

    Image: Freeport landslide east
    Image Owner: eos101



    Description:

    A small scarp and ledge to the hillside shows a general creep of land towards the water.
