The Earth Science Picture of the Day is pretty much my favorite photo blog. Regarding the Zodiacal Light, Rudi Dobesberger and blog curator Jim Foster wrote:

Zodiacal light is now thought to be caused by dust particles scattering sunlight in the orbits of comets. In both hemispheres it’s best observed in late winter/early spring after sunset and late summer/early fall before sunrise. However, it can be detected before astronomical twilight (morning) or after astronomical twilight (evening) at other times of the year as well, providing that the sky is quite dark.

A couple of weeks ago a reader sent me a link isleroyalewolf.org. The website documents the interactions of the island’s wolf & moose population as their decades long dance unfolds on this remote, wilderness island. Their overview explains:

Isle Royale has offered many discoveries… how wolves affect populations of their prey, how population health is affected by inbreeding and genetics, what moose teeth can tell us about long-term trends in air pollution, how ravens give wolves a reason to live in packs, why wolves don’t always eat all the food that they kill, and more. The wolves and moose of Isle Royale also frequently reveal intimate details of their daily life experiences and they have inspired numerous artistic expressions. If we pay attention, they all tell us something important about our relationship with nature. These insights and discoveries are all presented here for you.

Building on the graph above and to develop a deeper understanding, here is more on the history of wolves and moose on Isle Royale. Moose first came to Isle Royale in the early 20th century, and for fifty years, their numbers fluctuated with weather conditions and food abundance. Wolves first arrived in the late 1940s by crossing an ice bridge from Canada. The lives of Isle Royale moose would never be the same.

Every winter since 1958, a team of researchers has spent numerous weeks at Isle Royale observing the lives of these wolves and moose and reporting back. Now they offer a website with photos and detailed reports, a fascinating tale that I encourage you to follow. Today’s photo is from the edition I began with – It’s Complicated. A snapshot:

Isabelle’s signal was surprisingly close. By the time we saw her, she was running for her life, north along the beach of Rainbow Cove. She was being chased by Pip’s two companions. Pip was nowhere in sight. While those two wolves have been eating regularly, Isabelle may not have had a decent meal in weeks, perhaps longer. Isabelle’s half-mile lead was reduced to nothing in just a few minutes.

Definitely read on for photos and a gripping account of these wolves battling and follow the whole 2013 Winter Study as it unfolds (sign up for their email).

We’ll stay outside and under the stars with this photo taken across from Pickerel Cove Campground in Isle Royale National Park. Carl writes that he was trying to photograph the bright stars filling the sky while keeping his shadow out of the shot. He finally decided to go with it (to great effect in my opinion).

Check it out bigger in his Under the Stars slideshow.

Minong Mine

Nina went to Isle Royale in September and has been posting accounts on her awesome blog Black Coffee at Sunrise. This photo of Minong Mine appears in Day Five, which features a detailed description of their encounter with a pack of wolves:

Since the vegetation along the narrow trail was dripping with dew and leaning inward, it wasn’t long before we were both soaking wet from hip to ankle. Ten minutes after leaving our campsite, the ground became marshy and we found ourselves walking a long stretch of protective plank bridge. Just before reaching the stream crossing, the trail curved to the right and Craig suddenly stopped in front of me, turned around and said very calmly, “Uh…a whole pack of wolves…”

His voice trailed off as he turned back around to face forward again. I thought he was trying to be funny since I couldn’t yet see what was around the corner. After inching forward another foot or so, he turned to me again and the look on his face was priceless. “I’m not kidding,” he said. “There are at least five wolves on the trail ahead of us.” The next few moments were the most surreal and exciting I’ve ever experienced.

Read on at her blog for the rest of the account or see them all in her Isle Royale section.

Mt. Franklin view

Mount Franklin was named in honor of Benjamin Franklin. It’s along the Greenstone Ridge, about which Summit Post says:

The Greenstone Ridge forms the geologic backbone of one of America’s least visited National Parks…Isle Royale … The island is composed of a series of ridges that run the length of the island. In between these ridges are areas of swamp and muskeg. Sound inviting?

The Greenstone Ridge is the longest and highest of these ridges. It gets its name from the greenish stones that are commonly found along it. It runs the entire 45-mile length of the island and is anything but smooth. A few notable peaks along it include Mt. Franklin(1080’), Mt. Ojibway(1136’), Mt. Siskiwit(1205’), Ishpeming Point(1377’), and Mt. Desor(1394’). The ridge top is quite open in places, particularly along the northeast half of the ridge. The trail between Mt. Franklin and Ojibway is especially scenic.

Click to read more about this trail. The Isle Royale National Park site says that Greenstone Ridge forms the backbone of Isle Royale and is thought by many geologists to be a portion of the largest lava flow on earth.

This photo is part of Carl’s Isle Royale National Park set (slideshow), to which I am drawn back to again and again. You can also purchase many of them from Carl’s MackinacScenics site.

Mark writes:

This was one of my favorite photographs made during my last visit to the island in spring 2006. I’ve been to the wilderness isle many times and every time is special. It’s ruggedly beautiful, inspirational and one of the most exciting places in Michigan to make photographs if you appreciate pure nature.

You can see more from the island in Mark’s Isle Royale gallery, and more of Michigan in his other galleries and in his book Michigan, Simply Beautiful. Along with fellow photographer Mark also operates Great Lakes Photo Tours, providing personalized and in-depth instruction in nature photography in some of Michigan and the region’s most beautiful locations.

The entry for Rock Harbor Lighthouse at Terry Pepper’s Seeing the Light tells the history of this remote lighthouse and includes a number of historical photos. With the boom of mining on Isle Royale and the new lock at the Soo, a light at Rock Harbor was approved by Congress (for the outrageous sum of $5000). The light was completed in 1856 and:

The station’s rubble stone tower stood 16 feet 11 inches in diameter at the foundation, with its 49 foot 11 inch high walls tapering gently to a diameter of 14 feet 1 inch below the circular gallery. A set of spiral pine stairs supported by a central pine post wound within the tower from the first floor to a trap door in the gallery floor to provide access to the lamp. The lantern itself was fabricated of cast iron, and featured a domed copper roof. Centered within the lantern, a fixed white Fourth Order Fresnel lens sat at a focal plane of 70 feet above lake level, and cast its light 15 miles across the lake The attached rubble stone dwelling, stood 29 feet square and 20 feet 9 ½ inches high at the apex of the cedar shingled roof.

Carl took this photo at Herring Bay in Isle Royale National Park. It’s part of his super-cool Isle Royale National Park (slideshow) which, in addition to having many more kayak photos, has some incredible views of this amazing Michigan park including a sweet shot of the northern lights over Amygdaloid Island Ranger Station (plus he has them uploaded at “wallpaper size”).

This weekend, July 17-20, 2008, head up to Grand Marais for the 24th annual Great Lakes Sea Kayak Symposium. It’s the oldest kayaking symposium on the Great Lakes and offers paddlers of all ages and abilities for a weekend packed with fun and learning opportunities including on-the-water classes, classroom lectures, kayak demos and vendors, social events, a race and of course plenty of opportunities to paddle including guided tours of the Pictured Rocks National Lakeshore. Keynote speakers this year are adventure filmmaker and expedition sea-kayaker Justine Curgenven and Sam Crowley, who circumnavigated Ireland in 2007 in a sea kayak.

Moose Point Face-off

The Detroit Free Press reported that Michigan moose numbers are down:

The moose population in Michigan’s western Upper Peninsula appears to have dropped over the past two years and experts warn that a warming climate could be cause for concern for the species’ future in the state.

The latest biennial survey by the Department of Natural Resources produced an estimate of 323 moose in their primary Michigan range, which includes Baraga, Iron and Marquette counties. If correct, that would be a decline there of about 28 percent from 2013, when the estimate was 451.

…Even so, surveys since 1997 turned up regular population increases of about 10 percent. Beginning in 2009, the growth rate slowed to about 2 percent.

Now it appears to be dropping.

“It might not happen in our lifetime, or our children’s, but we have to face the possibility that there might not be a wild moose population in Michigan,” Chad Stewart (deer, elk and moose management specialist with the DNR) said.

Scientists are not certain what caused the apparent decline over the past two years, he said. Bitter cold and heavy snow the past two winters is one possible culprit. Also, wolves increasingly may be targeting moose because of falling deer numbers, although Stewart said there’s no hard evidence of that.

But in the long term, a warming climate may be the moose’s biggest enemy. Blood-sucking ticks thrive under such conditions. Thousands can attach themselves to a single moose and weaken the hulking beast.
