EUROPE AND NORTH AMERICA - SPREADING AWAY FROM EACH OTHER
DAY 6 : FRIDAY AUGUST 14, 2009
This day was a visit to the Þingvellir (Thingvellir) National Park. The area (an UNESCO World Heritage site) is not only beautiful but has many interesting points related to it.
It was the location of the world’s first parliament, the Althing, which first met in 930 AD. There was an annual meeting of chieftains at this location for over 300 years. Leaders were elected, cases argued, and disputes settled (not always without violence though).
The park is on a major geological point (as is all of Iceland) where the North American and the Eurasian plates are pulling away from each other. Another formation is called the Iceland plume which is a geological hotspot.
This geological fact gives us two things that are unique to this park.
The lake (Þingvallavatn) is growing as the two plates separate causing the local ground to sink lower. But since this is a volcanic area, periodically a volcano barely visible in the distance in the lake pictures erupts and fills in the valley. The lake then reforms as the land sinks again. Over and over.
The lake also has some unique types of fish in response to this geological cycle.
A trail follows the actual split between the two continental plates. Traveling from North to South, the right wall in the pictures is the North American Plate. On the left side, a less steep wall (in some areas) is the Eurasian Plate.
It was both fascinating and very humbling at the same time.

Photos from each day are shown in thumbnail (small) form. Panoramas are either wide or tall images, while normal photos are small rectangles. All photos shown in the PHOTO SHOWCASE section can be enlarged for better viewing. Photos will enlarge to fit your browser window width. Therefore, to view them at larger sizes simply make your browser window wider.
If there is any issue or the need to inquire/comment about an image, please refer to the Image ID label (see below) of the specific image along with the trip name found at the top of the browser window.
Video Clips
Depending on the browser, some of the controls may not always be supported.
Most videos will start playing automatically. Sound is automatically off even if included with a video. See D, E below for sound control.
A few small videos are set to loop endlessly, while most just play to the end.
A: To start or stop a video, click in this area (even if the symbol is not visible)
B: If a browser shows this symbol, clicking on it will restart the video from the beginning
C: Progress bar - will display total video time on the right.
D, E: This seems to have the most variants between browsers. If the video description says 'w/ sound’, you can adjust the volume with this control
If neither is visible, move the cursor to the E area and either E and/or D will be visible
If E is visible but not D, click on E
Once D is visible, slide the bar up or down to adjust the volumn
Panoramas
Clicking anywhere on a panorama thumbnail will cause the image to expand to fill the browser width. Clicking again anywhere in the browser window or scrolling the browser window will cause the expanded image to shrink back to its smaller thumbnail size.
The Image ID and description is found just below the thumbnail image on the left side.
Individual Photographs
If you click on any photo thumbnail, it will open a larger viewer which can be used to walk through all of the standard photos on the page. Once open, to go forward click on the > on the right side of the enlarged image. To scan backwards, click on the < on the left side. To close the larger images either click on the X in the upper right hand corner of the browser window or anywhere outside of the enlarged image.
The Image ID label can be found by hovering a cursor over the thumbnail image (may not be available on some tablets/phones) or, once enlarged, from the lower left hand side just under the image.
Additionally, in the same area as the Image ID (or the upper left corner for newer/updated sites) a count showing the current image number versus the total number of images available for viewing.
For newer or updated sites (look for the orange checkbox in the header of a sites main page), additional buttons have been added when viewing a full size image. From left to right, the buttons are:
Email: will open an email with information and a link to the current image
WhatsApp: if WhatsApp is on your system, will open a browser window to open WhatsApp and create a message with information and a link to the current image
FaceBook: Will open a browser window to open Facebook and create a message with information and a link to the current image
full screen: will take over the entire display versus just the browser in most systems; ESC returns to the brower only mode
magnify: enlarges the image within the browser or full screen; if the image is larger than can be displayed it can be scrolled
exit: will close the large image viewer returning to the thumbnails
