Via the official GNP fbook page:
Glacial lakes and their outlet streams tend to have very low nutrient levels, a condition described scientifically as "oligotrophic." The oligotrophic waters of the park are largely due to being located near the headwater source of the watersheds, local surface geology, lack of nutrient input from either human or natural sources, cold water temperatures, and short growing seasons."
Which explains the low/lack of algae.
As to the coloration, it doesn't translate well in this picture, but glacial lakes tend to look green (Wikipedia calls it turquoise), due to the aforementioned rock flour, which is derived from jasper.
On second thought. Maybe the pictures are better.
The link works. I've never been to Scotland, but I've done a bit of research on rocks of the area. Here's a good overview: Pattison & Harte 1997
I have some thin-sections scanned, but the rocks are so fine-grained (mostly slate) that they're not really worth posting unless you're really interested
Perhaps that's the name of the inland water on the righthand side, but that was definitely Palm Beach. I was at the Barrenjoey Lighthouse, see this google map
Michigan side: 46°38'7.29"N 87°27'44.69"W
This is a point not brought up enough. As a childhood shark literature enthusiast, I learned that the overwhelming majority of shark attacks occur due to mistaken identity and otherwise unsafe behavior. Most sharks have awful eyesight; a paddling surfer may resemble a seal and, especially if there are other factors that draw attention to the human (e.g. scent of blood, urine in the water, or the gleam of shiny jewelry), provoke a shark attack.
More to the point of sharks' distaste for human flesh, it is extremely rare that a shark will bite a swimmer in the first place, let alone biting multiple times. Once the shark realizes that its prey is not, in fact, the desired fish or sea mammal, the shark will (depending on species and behavior) generally release and swim away. If the shark locks on, some prodding and poking (aim for the eye!) may be necessary.
Bisheh Waterfall is in Khorramabad, which is in Lorestan, which is in Iran, which is not near Kashmir.
That's a render, which means that it's primary purpose is to serve as an Olympic symbol - it doesn't need any other purpose, really.
That having been said, this link talks about how it does a fairly good job of being self-sustaining:
>Its design makes it store solar energy during the day, while the surplus energy produced is piped to pump sea water within the tower giving the effect of a waterfall outside. This water is reused simultaneously by turbines which are designed to produce energy during the night
Thanks, fellow Columbusian?
ninjaedit: One thing I love about photography is that you can find these little nuggets of interest in your own backyard, sometimes literally.
Here's an album of some shots I like that I took around Columbus, feel free to take a look! https://www.flickr.com/photos/59811279@N08/sets/72157644422354033/

My guess is it’s off or near the Greeter Falls trail. https://www.alltrails.com/trail/us/tennessee/greeter-falls-loop-greeter-trail If not exactly there, there are similar caves and swimming spots all along that trail and throughout the Savage Gulf nature area.
Looks amazing, but you certainly pay for it. Looked up the price for a standard double: $ 640 per night. Great reviews though.
