Note: Though periodically updated, the red polyline on the Google map may not be in perfect sync with a given water flow’s course, due to the continual updating by Google of their aerial projections and algorithms, as well as natural water flow course-direction changes.
This Google Map web page is “mobile-friendly” down to a “320x480-pixels” screen-size. But, due to the nature of maps, the larger the screen this web page is viewed on, the better. Browsers that are not “matchMedia” capable (such as Internet Explorer 9) will not receive automatic “zoom-level” adjustments at smaller screen sizes to optimize the map’s appearance.
