Today I will post the rest of the pictures from Friday's canoe trip up Grand Marais Creek into Grand Marais Lake. It is the first time I have ever even seen Grand Marais Lake. A couple of times in the winter I snowshoed to the area on the creek where we launched.
What a beautiful day it was for a canoe ride.
For 12 years my sister, Diana, and I have been getting together the end of September to enjoy fall colors, various adventures, and each other's company. This is the weekend. Di arrived in Grand Marais late afternoon. We had dinner and then went out to enjoy sunset. Here are a few pictures I took at the Sable Lake boat ramp.
Before going to Sable Lake, we went to the boardwalk to see sunset and moon rise.
This blog displays scenic photos taken from around Grand Marais, MI. Photos of rockhounding and nature adventures are also posted. Information is included about the Gitche Gumee Agate and History Museum and other scientific subjects.

Grand Marais Creek and Lake Canoe Trip -- Post 1
For weeks now my friend Renee's husband, Bob, has been asking me to go caneoing. Yesterday was finally the day. We both have one-person canoes, which we loaded on to our respective vehicles and drove east of town. Then we drove down a two-track around a mile, parked, and unloaded the canoes.
In years past it was not possible to canoe the Grand Marais Creek. However, beavers have been busy and have built a series of very effective dams that have tripled the width of the river.
Here is one of the dams. It doesn't look like much, but it spans the entire width of the creek and absolutely stops the flow. In fact while sitting in my canoe in front of the beaver dam, there was no current.
The fall colors were terrific. Notice the huge tree below that is horizontal, but still alive.
As we canoed up river, we stopped every once in a while so Bob could fish. Here are a series of pictures documenting the catching of the only Brook Trout he caught yesterday. Since it was sunny, it was not a great day to fish. But it was beautiful and a great day to be on the river.

Night Photos
Today was the last day for me to work at the museum for the year. Thanks to friend, Jill, who is going to watch the museum this weekend -- the final weekend of the year. The hours will be 2-5 Friday and Sunday; Saturday will be noon to 5 if there are people. If it is slow, I told Jill she could close an hour early.
Thanks to everyone who visited the museum this summer, especially to those who purchased the book, rocks, mineral art, or other items. All gift shop sales support the museum and will help to hopefully keep the doors open.
But since it was my last day at the museum for the season, I decided to take an hour or so off to visit a friend. On the way home I snapped a few night photos.
After pulling up my driveway, I took this picture of one of my apple trees. Then I played on Photoshop using filters to change the image. Interesting.

Gemini Observatory Images
While working on the online rockhounding adventures, I was trying to track down a a source for a graphic I want to use. I found out that it was produced by staff at the Gemini Observatory, located in Hawaii. Gemini was built and is operated by a partnership of seven countries including the United States, United Kingdom, Canada, Chile, Australia, Brazil and Argentina. The mission statement for Gemini is: To advance our knowledge of the Universe by providing the international Gemini Community with forefront access to the entire sky. Any astronomer in these countries can apply for time on Gemini, which is allocated in proportion to each partner's financial stake. The Gemini Observatory consists of twin 26.5 feet (8.1 m) diameter optical/infrared telescopes located on two of the best observing sites on the planet. From their locations on mountains in Hawaii and Chile, Gemini Observatory’s telescopes can collectively access the entire sky. The first picture below was taken inside Gemini North. The second picture is Gemini South.
The Frederick C. Gillett Gemini North telescope is located on Hawaii's Mauna Kea as part of the international community of observatories that have been built to take advantage of the superb atmospheric conditions on this long dormant volcano that rises about 4,200 meters (13,800 feet) into the dry, stable air of the Pacific. The Gemini Observatory's international headquarters is located in Hilo, Hawai`i at the University of Hawaii Hilo's University Park. The Gemini South telescope is located at about 2,750 meters (8,900 feet) elevation on a mountain in the Chilean Andes called Cerro Pachón.
When I went to their web page, I found some great photos. First, is a great picture of a portion of the Lagoon nebula (Messier 8, or M8), which is among the most striking examples of a stellar nursery in the Milky Way galaxy. Argentinean astronomers Julia Arias and Rodolfo Barbá have used the Gemini South telescope to obtain a dramatic image of the "star nursery" that is located some 5,000 lightyears away. The multi-hued scene is truly a psychedelic "flashback" as its photons had to travel through space for 5,000 years before they reached the gigantic Gemini 8-meter mirror. Astronomers sometimes call the region imaged the “Southern Cliff” because it resembles a sharp drop-off. Beyond the “cliff,” light from a spattering of young background stars in the upper left of the image shines through the cloudscape.
Arias and Barbá obtained the imaging data to explore the evolutionary relationship between the newborn stars and what are known as Herbig-Haro (HH) objects. HH objects form when young stars eject large amounts of fast-moving gas as they grow. This gas plows into the surrounding nebula, producing bright shock fronts that glow as the gas is heated by friction. The researchers found a dozen of these HH objects in the image. They also found that most of the newborn stars are embedded in the tips of thick dusty cosmic clouds, which have the appearance of bright-rimmed pillars.
The Lagoon nebula is located in the direction of the constellation Sagittarius in the southern Milky Way. Viewed through large amateur telescopes, it appears as a pale ghostly glow with a touch of pink. If you want to try to find M8 yourself, information is available at: http://www.themcdonalds.net/richard/index.php?title=Finding_M8
The next image is of a newly discovered nebula,Kronberger 61, that shows the ionized shell of expelled gas resembling a soccer ball. The light of the nebula is caused by the emission from twice-ionized oxygen. The originating star can be seen as the slightly bluer star very close to the center of the nebula. Below the bright star at left is a barred spiral galaxy in the distant background, careful inspection will reveal several additional distant galaxies in the image. The most amazing thing about this image is that it was found in partnership between an amateur astronomer and a professional.
This long-duration fish-eye view of the Gemini North telescope facility shows the glow of both dusk and dawn, as well as star trails, and the orange glow of the Gemini LGS laser as it tracks through the sky. The LGS laser from the W.M. Keck Observatory and the peak of Haleakalā on Maui can be seen on close examination of the image. The bright streak on the left is the setting moon.
This image is a Gemini artist's conceptualization of the environment around the super massive black hole at the center of Mrk 231. The broad outflow seen in the Gemini data is shown as the fan-shaped wedge at the top of the accretion disk around the black hole. This side-view is not what is seen from the Earth where we see it ‘looking down the throat’ of the outflow. A similar outflow is probably present under the disk as well and is hinted at in this illustration. The total amount of material entrained in the broad flow is at least 400 times the mass of the Sun per year.
This image is a composite of three color images taken on Nov. 18, 2010, by the Gemini North telescope in Hawaii. The composite image shows a belt that had previously vanished in Jupiter's atmosphere is now reappearing.
Image of NGC 6872 (left) and companion galaxy IC 4970 (right) locked in a tango as the two galaxies gravitationally interact. The galaxies lie about 200 million light-years away in the direction of the constellation Pavo (the Peacock).
This is a Gemini artist's concept drawing of W33A showing the accretion disk (yellow/orange), torus (dark ring around disk) and bi-polar outflow jets (blue) within the dense clouds of its stellar nursery.
Explaining how the most massive stars are born, deep within their stellar nurseries, is one of the most persistent mysteries in modern astronomy. Now, observations at the Gemini Observatory provide convincing new evidence that these stellar heavyweights may be born in much the same manner as lightweights like our Sun.
This Gemini artist's rendering of what HD 131488's inner planetary system might look like as two large rocky bodies collide. HD 131488 is located in the direction of the constellation Centaurus and is three times more massive and 33 times more luminous than our own Sun
Using the Gemini South telescope in Chile, astronomers at UCLA have found dusty evidence for the formation of young, rocky planets around a star some 500 light years distant. But these potential extrasolar worlds are alien in an even more intriguing way… In the aftermath of collisions between planetary embryos around this star the researchers discovered that the dusty debris bears no resemblance to the planetary building blocks of our own Solar System.
