How Does a Sundial Work?

Many people have seen the old sundial which still sits in close proximity to where the first Huletts hotel stood. To the best of my knowledge, it still keeps pretty accurate time. As the summer draws to a close, I thought this might make an interesting post.

Wikipedia has a long description about sundials here but I present the “short version” below.

A sundial is a device that measures time by the position of the Sun. In the most common design, the sun casts a shadow from its Gnomon, a thin, straight edge onto a flat surface marked with lines indicating the hours of the day. As the sun moves across the sky, the shadow-edge progressively aligns with different hour-lines. Such designs rely on the Gnomon being aligned with the axis of the Earth’s rotation. For a sundial to work correctly in the northern hemisphere, the Gnomon must point towards true north (not the north magnetic pole) and the Gnomon’s angle with horizontal must equal the sundial’s geographical latitude. Huletts Landing’s latitude is 43.6392326355 degrees.

The shadow-casting Gnomon must be in a fixed position and aligned with the Earth’s rotational axis. It must be oriented with true North, making an angle with the horizontal equal to the sundial’s geographical latitude. This axis can only be aligned with the celestial north pole, which is closely aligned with the (present) North star, Polaris. In other words, it can’t be positioned with a compass, it must be positioned with the North star.

If the shadow-casting gnomon is aligned with the celestial north pole, its shadow will revolve at a constant rate, and this rotation will not change with the seasons. That’s why a sundial works through all seasons of the year.

So while I don’t know the year the sundial was put in place, I can say with some certainty that it was positioned at night and those putting it into place stopped and found the North star. Our proof is that it still works today.

So as Labor Day brings this summer to a close, have a great break and a good rest.

New Informational Flyer on Asian Clam

A new public informational flyer about Asian clam, an invasive species identified in Lake George for the first time this August, has been released. The flyer explains how citizens can help to identify and prevent the spread of this clam. The flyer is available here.

Designed specifically for Lake George, the flyer will help the general public discern the Asian clam from the native mollusks that live in Lake George and pose no threat. The Asian clam is a very small and round bi-valve. It is typically less than 1.5 inches in size, and can spread rapidly. A single clam can reproduce alone, and can release hundreds of juveniles per day. The biggest problem Asian clams have caused in other water bodies is biofouling – or clogging of water intake pipes.

Officially known as Corbicula fluminea, the Asian clam is native to southern Asia, the eastern Mediterranean and Australia. The Darrin Fresh Water Institute found it off Lake Avenue beach in Lake George Village on August 19. Up to 600 clams per square meter were documented, covering an area of approximately 2.5 acres.

Spearheaded by the Darrin Fresh Water Institute, a committee has formed to coordinate response efforts. Representatives from the Darrin Fresh Water Institute, Lake George Park Commission, Lake George Association, FUND for Lake George, NYS Department of Environmental Conservation, Adirondack Park Agency, Adirondack Park Invasive Plant Program, and Lake Champlain Basin Program are working together to pool resources and expertise. Their next step is to determine the extent of the spread of the clam, map the extent of the invasion, and then weigh options for eradication or management. The hope is that the infestation has been discovered soon enough to successfully eradicate it.

The public is asked to look for the clams in sandy or gravelly bottom areas of Lake George, in shallow, warm water; this is the clam’s preferred habitat. If a clam is found that matches the description of the Asian clam, citizens are asked to get a sample or take a photograph and call the Lake George Association at 518-668-3558.

In addition, the public can avoid spreading the Asian clam, as well as other invasive species, by following these guidelines whenever leaving a waterway:

Check and remove any visible mud, plants, fish or organisms from boats, trailers, equipment, clothing, dogs, etc.
Clean and eliminate water from equipment. Be sure to drain all water, including live wells and bait buckets.
Do not use Asian clams as bait.
Dry anything that comes in contact with the water.
Never release plants, fish, or other animals into a waterway unless they come from that waterway.
Print out, distribute, and post the informational flyer in your place of business.

LGA Receives Froehlich Foundation Funding


LGA lake saving projects, like the dry well installation at Bixby Beach shown here, are made possible in part through funding support from the Helen V. Froehlich Foundation.

Lake George, NY – August 30, 2010 – The Lake George Association announced today that the Helen V. Froehlich Foundation has awarded the 125-year old conservation organization a grant of $378,500 for lake-saving initiatives. This is the LGA’s seventeenth consecutive award from the Froehlich Foundation. This grant award will provide $174,500 toward lake saving projects, $56,000 toward education and outreach programs, and $123,000 toward lake quality programs, including Citizen Science and the Citizens Statewide Lake Assessment Program, Invasive Species Management, and Lake Stewards.

“The LGA is grateful for the Foundation’s continuing support, as well as their vote of confidence in the LGA and our efforts to protect the Lake and its watershed for future generations,” said Walt Lender, the LGA’s executive director.

Nearly half of the total grant award will provide funding for the LGA’s Lake Saving Projects. These construction projects improve Lake George’s water quality by preventing sediment and pollutants from entering the lake. “The funds in the grant award, leveraged with our members and donors generosity, put us in a strong position to receive significant funding from public sources, which in turn, extends our ability to complete more projects to protect the Lake,” he said.

The LGA’s popular Floating Classroom program will receive $23,000 to help teach lake science and watershed management to area students. Over 1,000 area students benefit each year from the LGA’s Education and Outreach programs, which are provided free of charge through grants like the one provided by the Froehlich Foundation.

LGA staff also educates homeowners, businesses, municipalities and landscapers about improving water quality by installing vegetative buffers, reducing lawn size and non-permeable surfaces, controlling stormwater runoff through rain gardens and rain barrels, and using no-phosphorus fertilizer and native plant species in landscaping.

The 17 consecutive grant awards from the Froehlich Foundation represent over $5 million dollars worth of improvements to Lake George and the watershed.

Established in 1885, the Lake George Association is America’s first lake association and a pioneer in the conservation movement. The LGA spent over $900,000 in 2009 to carry out its mission to protect Lake George. In addition to the funding from the Froehlich Foundation, the LGA relies on income from membership support and fundraising events.

After reading the entry about the Bald Eagle sighting I wanted to share that we also saw a bald eagle the first week of August, just past lands end. We sat there in the boat and watched for a while. He/She didn’t seem to mind us, and preened.

Email to the Editor

Dear Editor:

The Lake George Association is concerned about the decision made by the Department of Environmental Conservation to discontinue retrieving garbage from collection centers on the Lake George islands. We urge the DEC to reconsider this decision and ask local citizens who love Lake George to join us in finding a better solution.

Expecting our natural resources to bear the burden of cost cutting is fiscally irresponsible. At the LGA, we believe that the cost of cleaning up this problem will be higher than preventing it from happening in the first place.

Alternative solutions could result from a dialogue with Lake users. The LGA has considerable experience on the Lake and a deep understanding of boating, recreation and water quality. Given the opportunity to discuss the situation with the DEC, we could help find a solution that continues to protect Lake George and the water we use for drinking, swimming, fishing and boating.

While the “carry in – carry out” policy is ideal in theory, trash finds its way into the Lake regardless of policies. One isolated example: after Log Bay Day 2010, the LGA hauled away several large bags of trash.

Even conscientious Lake users need a convenient way to dispose of trash. It is considerably easier to empty trash at a central collection point than to clean up wind-blown garbage, especially when it has left an island and gone on to desecrate the Lake.

To allow trash to enter Lake George — after generations of exemplary stewardship by DEC staff — would be shameful.

Sincerely,

C. Walter Lender
Executive Director
Lake George Association

Diseased Oak Tree Taken Down

Unfortunately, the oak tree near the Casino could not be saved after it lost a large limb last week.

It was taken down on Wednesday, July 21st.

Here is a short video, with some comments by the men who cut it down, on how old it might have been.

Great Oak Loses Part


The long-standing red oak tree near the Casino, lost one of its limbs on Thursday, July 15th.

This picture was taken shortly after the large oak tree next to the Casino lost one of its limbs on Thursday. After it was cut up, I attempted to count the rings to see how old it was. Because of the way it was cut, I had to count 1/2 way up the limb. I counted 115 rings, so the limb would be approximately that old.

I would guess the tree itself is about 250-300 years old.

32 Aboard Saturday’s Excursion

While I was unable to attend Saturday’s trip aboard the Lake George Association’s Floating Classroom, there were 32 people on board who learned much about the ecology of Lake George. If you missed the boat (sorry I know it’s a bad pun), don’t worry, the Floating Classroom will be returning to Huletts in August.

Thank you Friends of Historic Huletts for sponsoring this worthwhile event and thank you Lake George Association for providing this valuable resource.

Invasive Species Awareness Week Begins July 12th

Lake George’s Invasive Species Awareness Week (ISAW) begins next week, and coincides with the release of a new report by the New York State Invasive Species Council. Entitled: A Regulatory System for Non-Native Species, the report has been sent to Governor Patterson and the legislature for review.

Those interested in learning more about invasive species impacting Lake George and efforts currently in place to prevent their spread, or discussing the new regulatory system proposed by the state council, are invited to stop by the ISAW display at the Visitors Center in downtown Lake George, from 11 am – 4 pm, Monday – Friday, July 12 – 16. Representatives from the Lake George Association, the Cornell Cooperative Extension, Warren County Soil and Water Conservation District, and other area organizations will be on hand.

Due to a lack of natural predators, diseases and parasites, invasive species can quickly become pervasive. When they do, these species can negatively impact the ecological balance of Lake George by out-competing native species for light, nutrients, and space.

The new report by the NYS Invasive Species Council introduces a process for assessing level of threat, assessing socioeconomic value, and assigning each invasive species into a distinct category for appropriate action.

State Environmental Conservation Commissioner Pete Grannis said, “New York needs to take action now to curb the many pathways that invasive species use to make their way here. The system the Council is proposing strikes the right balance of minimizing the major threats to our ecology and economy
while allowing for the careful use of those plants and animals that pose lower risks.”

The new assessment process would allow the state to categorize invasive species as “prohibited,” “regulated” or “unregulated.” Species in the “prohibited” category would be the most restricted as they pose clear risks to New York’s economic, ecological and public health interests, and, therefore, would be banned from commerce entirely. “Regulated” species would be restricted, but not prohibited from commerce, and would require practical and meaningful regulatory programs. “Unregulated” species would be identified as those non-native species that do not pose a threat and therefore could be used freely in commerce.

Two “tools” would be used in assessing risks from non-native plants and animals. One evaluates the inherent, biological “invasiveness” of each species, i.e., some species are better “weeds” than others. The other tool looks at socio-economic values to help determine whether the social benefits of a plant or animal outweigh the potential harm. For example, earthworms have often been shown to have positive effects on soil structure and fertility in agricultural and garden ecosystems; however, glacial ice sheets that covered most of New York some 11,000 to 14,000 years ago left New York worm free. Today’s worms are actually European invaders and considered a non-native invasive species, but are clearly valuable.

The New York State Invasive Species Council’s final report is available online at http://www.dec.ny.gov/animals/63402.html.
