Wikipedia says that Portage Lake is part of the Keweenaw Waterway, a partly natural, partly artificial waterway that cuts across the Keweenaw Peninsula to provide access for shipping from Lake Superior. If you click the link you can get an aerial view.
Saw the fog on Lake Portage from my apartment window after I woke up today. I knew the potential this fog can bring so I darted down to the lake shore. But the fog was so heavy that the foliage on the other bank were completely blocked. Just when I was about to give up and head back for school, the fog started to break as the sun rises. And then the magic started to unfold before my eyes. Soon the fog lifted and fill the campus uphill, the entire campus was bathed in soft morning light and there were Tyndall effect everywhere! I can not think of a better way to start a day of work.
What’s the Tyndall effect you ask? The UC Davis ChemWiki explains that the Tyndall effect was identified by 19th Century Irish scientist John Tyndall.
Because a colloidal solution or substance (like fog) is made up of scattered particles (like dust and water in air), light cannot travel straight through. Rather, it collides with these micro-particles and scatters causing the effect of a visible light beam. This effect was observed and described by John Tyndall as the Tyndall Effect.
The Tyndall effect is an easy way of determining whether a mixture is colloidal or not. When light is shined through a true solution, the light passes cleanly through the solution, however when light is passed through a colloidal solution, the substance in the dispersed phases scatters the light in all directions, making it readily seen.
For example, light is not reflected when passing through water because it is not a colloid. It is however reflected in all directions when it passes through milk, which is colloidal. A second example is shining a flashlight into fog or smog; the beam of light can be easily seen because the fog is a colloid.

Linda writes that this photo is taken about 400 feet above Lake of the Clouds on the Escarpment Trail, which starts at Lake of the Clouds Overlook. She says that if you go the whole loop it’s 8 miles, but 2 or 3 miles along the trail you get the most beautiful views of the Lake.
There’s at the Porcupine Mountain State Park website including a map of the Escarpment Trail & Lake of the Clouds area and more Lake of the Clouds on Michigan in Pictures!

Although this photo of the Spray Masters isn’t a TBT (Throwback Thursday) it sure feels like one!

I am officially giving in to the TBT (ThrowBack Thursday) meme. I love history too much to let everyone else have all the fun…
Don writes that Burt Lake Scenic Tower had an early Carl Zeiss 42 Power Telescope for patrons to use, which was a very big deal at the time. See it big as a tower and see more in Don’s massive Photo Tribute to Michigan Historian Dave Tinder slideshow.

Michigan State University, the University of Michigan and Wayne State University, the three universities that make up Michigan’s University Research Corridor (URC), have released a report titled “Innovating for the Blue Economy“. The report cites nearly $300 million in awards for water-related research and outreach from 2009 to 2013 that have led to innovations from dealing with invasive species and monitoring water quality to finding ways to optimize water use in agriculture. Their news release on the report prepared by the Anderson Economic Group (AEG) says in part:
AEG’s analysis showed that Michigan ranked fourth in the nation in the percentage of jobs associated with industries related to water, at 718,700.
“One in five Michigan jobs is tied to having good and plentiful water,” said AEG founder and CEO Patrick Anderson. “It is an important economic driver in Michigan, and extends to Great Lakes shipping, advanced manufacturing, agriculture and fishing, and over 80 other industry subsectors where Michigan workers are employed today.”
While most of Michigan’s water-related jobs are in water-enabled industries such as agriculture, mining and manufacturing, about 138,000 are in core water products and services producing water treatment facilities and solving water quality and quantity issues.
“Water isn’t just Michigan’s defining characteristic but the foundation of life on earth,” said Michigan State University President Lou Anna K. Simon. “Our three universities make significant commitments to support water-related research and programs. These not only support Michigan’s economy and quality of life, but position the state as a knowledge wellspring for the world’s most precious natural resource.”
Read on and read the full report right here. The report is chock full of interesting facts including that those 718,700 jobs represent 21.3% of Michigan’s total employment (4th in the nation) and details many of the accomplishments of Michigan’s investment in our “Big Three” university research programs. Also note that “downstream” industries like tourism that rely on healthy water resources aren’t included in the numbers.
