6. Using panorama photography to monitor changes over time
Now we will visit a couple of places where we were able to obtain panoramas from before and after the Sanford fire.
First, click on the “West Fork Hunt Creek Aspen Burn” location.

This “cubic” panorama shows the location after the burn. A link to the left of the panorama will let you view the same location in a panorama we took in the same place a year before the Sanford Fire.
Click on the Link to “View this same cubic panorama of the West Fork of Hunt Creek before the burn.” This panorama will open up in a second new page and you should be able to position both panoramas on your screen where you can see both of them at the same time. Both of these cubic panorama windows are exactly the same size and they begin by opening up looking downstream in the same direction. You can compare the panorama views by moving each one the same distance to the left or right, or up and down, to see the dramatic differences in how the trees and stream look at the two different dates. You can imagine how dramatic this sequence would be if monitoring photography was taken periodically from the same exact spot for the next 10 or 25 or more years.
Now you can close the page showing the “before” burn view, and we will quickly demonstrate an additional “before and after” location where panoramas were taken.
Please go back again to the Sanford Fire 2002 Map by clicking on the “Sanford Fire” navigation text link at the top of the panorama page.
This time click on the “West Fork Hunt Creek” location link.

This panorama shows the effect of a flood event on the stream. This is a cubic panorama and you can see the soil deposited by the flood and also new sprouting plants at your feet. Zoom in on the plants for a closer view. A link to the left shows the same view, but with a new perspective.
Click on the link to the left of the panorama to “View the Full Screen West Fork Creek Before and After panorama”. This new view shows two panoramas “stacked” on top of each other in the same window. One panorama was taken a year before the fire/flood event and the other after. You can scroll both pictures at the same time to the left or right and the views stay the same for both pictures as you do so. Note also that these are not cubic panorama views. You can also “zoom” in on these panoramas with the “shift” key but the detail quality will not be as sharp as the larger window and higher resolution cubic view. You can close the “stacked” window now.
Other examples of “before, during and after” and “stacked” panoramas can be viewed at the “West Fork Hunt Creek Overlook” site on the Sanford Fire 2002 map. The Pass Creek Channel Stabilization project also displays before and after stacked views.
