Clicking on an event in the timeline will display a pop-up window that has more detailed info about the event.
You can click on the timeline and drag it left and right.
You can use the scroll wheel on your mouse to move it left and right.
Double clicking a point on the timeline will bring that point to the center screen.
There are three "bands" on the timeline. The top band goes by the year. The middle band goes by the decade. The bottom band goes by the century. The lower bands are handy for moving back and forth on the timeline quickly.
The detailed text for the timeline entries comes directly from The Lake Whatcom Watershed- A Retrospective
Resource Directory published in 2008 for the Whatcom County Public Works Department.
