  1. Root systems

    Root systems by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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

    Less landslide activity by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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

    Snow by eos101 from the GigaPan Freeport Landslides (West) by eos101

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

  4. Lower Scarps

    Lower Scarps by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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

    Uprooted trees by eos101 from the GigaPan Freeport Landslides (West) by eos101

    These trees may have been uprooted with the landslide activity.

    Epic struggle by eos101 from the GigaPan Freeport Landslides (West) by eos101

    Walking on mud flats takes practice, apparently.

  7. Scarp

    Scarp by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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 probably growing before the slide- the trees here seem to have been uprooted and tilted with the slide.

  8. Pile of debris at bottom of bank

    Pile of debris at bottom of bank by eos101 from the GigaPan Freeport Landslides (West) by eos101

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

  9. Land shifting

    Land shifting by eos101 from the GigaPan Freeport Landslides (West) by eos101

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

  10. Evidence of landslide

    Evidence of landslide by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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; some of the trees are uprooted or growing at an angle, suggesting that they moved with the sediment.

  11. Slow-moving debris slide

    Slow-moving debris slide by eos101 from the GigaPan Freeport Landslides (West) by eos101

    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.

  13. Freeport 11

    Freeport 11 by eos101 from the GigaPan Freeport landslide east by eos101

    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 would cause them to fall into the water.

  14. Freeport 10

    Freeport 10 by eos101 from the GigaPan Freeport landslide east by eos101

    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

    Freeport 9 by eos101 from the GigaPan Freeport landslide east by eos101

    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

    Freeport 8 by eos101 from the GigaPan Freeport landslide east by eos101

    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 most likely be characterized as debris slides, where small particles of rock matter move down the bluff without folding over each other.

  17. Freeport 7

    Freeport 7 by eos101 from the GigaPan Freeport landslide east by eos101

    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

    Freeport 6 by eos101 from the GigaPan Freeport landslide east by eos101

    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 creeping grass. This causes the dirt to become oversaturated, increasing the porewater pressure to a point that causes a landslide.

  19. Freeport 5

    Freeport 5 by eos101 from the GigaPan Freeport landslide east by eos101

    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

    Freeport 4 by eos101 from the GigaPan Freeport landslide east by eos101

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

  21. Freeport 3

    Freeport 3 by eos101 from the GigaPan Freeport landslide east by eos101

    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

    Freeport 2 by eos101 from the GigaPan Freeport landslide east by eos101

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

  23. Freeport 1

    Freeport 1 by eos101 from the GigaPan Freeport landslide east by eos101

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