fluke shadow

We got an interesting request a couple of weeks ago from Chris Gabriele, a whale biologist at Glacier Bay National Park: would we be willing to come out to the park and help give flukes to a tail-less whale?

Snow was a humpback whale first identified in the waters of Glacier Bay in the 1970s. She was struck and killed by a cruise ship in 2001. Local volunteers and GBNP personnel cleaned and collected her bones and sent them off to be re-articulated by a company in Maine. In 2014 the bones returned to Bartlett Cove, where they were put on display. The huge skeleton, about 45 feet long, is a wonderful addition to the park. It’s strange and beautiful and awe-inspiring, and thousands of people marvel at it. I always spend some time looking at it when I’m out there; I posted some sketches and thoughts about it here.

But for many people, there is something missing–some satisfaction absent, a question un-answered: where are the flukes? Flukes are perhaps the most iconic parts of whales–especially of humpback whales, who often lift their flukes above the water’s surface. But there are no bones in whale flukes; their shape is created by dense, fibrous tissue covered with fat and skin. So as interesting as Snow’s skeleton is, it feels out of balance, somehow lacking, without the flukes.

Hence Chris’s request. Could we somehow add flukes to the skeleton display? There had been a lot of talk about ways to do that; one idea was to outline them with metal on the skeleton somehow (that’s what was done for the killer whale skeleton at the Gustavus library). But Chris felt (and we agreed) that the bones should speak for themselves–the flukes should be subtle. How about creating an outline of them on the ground below?

We started with a photo of Snow’s flukes, plus their dimensions (measured when she washed ashore). First we calculated where the flukes would lie, in relation to the skeleton. Then we measured out the flukes’ 15-foot-plus width, tip to tip, and their 3.5-foot depth, and marked the tips and notch with stones. We laid the rope out to “sketch” the shape on the ground, then dug a little trench to draw the outline. Next we were off to the nearby beach with a bucket, to gather golf-ball-sized granite stones, which we hauled up to the work site and set in the trench, forming a pale, pebbly outline.

It looked pretty good, but felt incomplete somehow. Perhaps we should fill in the outline… we went back down to the beach and gathered buckets of coarse sand, poured it in our stony outline, smoothed it, and stepped back… Perfect! The dark sand, peppered with white shards of barnacle shells, created a subtly different value and texture below the skeleton: the shadow of Snow’s long-gone flukes. In the photo above, the caudal bones are just above the edge of the picture.

Sad news

In sad resonance with the recent installation of the skeleton of “Snow” at Bartlett Cove, a well-known local whale has been found dead near Juneau. We humans called her “Max”, or, less romantically and more scientifically, Whale #539 in the Southeast Alaska catalog.

Necropsy results indicate that she was probably killed when struck in the head by a ship.

She was known to frequent Glacier Bay and Icy Strait. It’s interesting how, with the advent of fluke pattern identification, we can begin to compose for a wild whale the kind of obituary that’s ordinarily reserved for humans and our domestic creatures. For example, “Max” was first seen in the 1970s, so we know she was at least 40 years old. She was a mother to at least five calves, and grandmother to at least three.

Of course the obituary the whales might compose would be so much richer…

You can read more about Max’s death and the investigation, and see some photos, on the Alaska Dispatch News webpage. You can see Max’s fluke on this page of the Southeast Alaska humpback whale fluke catalog. She’s number 539.

The most recent post was about the orca skeleton at the Gustavus Library… now here’s one about our other local whale bones—the 45-foot-long skeleton of “Snow” that is currently being installed at Bartlett Cove, in Glacier Bay National Park. The bones arrived last week on the ferry, and within just days the re-articulation is starting to take shape. I went out on Friday with some friends to see the progress, and had time to do a few sketches in the drizzle outside the shelter.

A humpback’s skull, I discovered, is utterly alien territory! I love skulls, and have sketched an illustrated hundreds, but this one had me tilting my head a lot—just trying to locate the analogues of familiar mammalian skull features was a challenge. For example, after observing and drawing for about 45 minutes, I finally realized that areas I had been thinking of as “forehead” were actually more analogous to the hollows between zygomatic arches and nasal opening…

Plus, the whale skull presented such different shapes from different angles! From the side, like a bird, from the front and back, like…?

I realized that I didn’t put anything in for scale in my sketch page, so I’ve also added a photo of the crew at work placing the skull.

The whale in the library

Last February, the wonderful Gustavus Public Library got a wonderful addition: the skeleton of a killer whale calf. The animal was found dead in Glacier Bay in 2005. Over the next several years the bones were cleaned (a smelly and long process), then rearticulated into a complete skeleton. Community members assisted in the re-articulation process, which was led by Lee Post, a specialist from Homer. On completion, the skeleton was welcomed to the library with song and dance—including presentations, music, and a ceremony by members of the Hoonah Indian Association, who gave the whale a special name: Keet’k’ (little killer whale). 

Now Keet’k’ swims above the entrance to the kids’ reading room. I love reading and researching in her shadow, glancing up every now and then to study her magnificent and graceful bones.

We’ve returned to Gustavus for the summer season, and already this remarkable area is demonstrating its summer abundance. Gustavus is a small community on a broad glacial outwash fan fronting Icy Strait, at the mouth of Glacier Bay. This region is a confluence of powerful tidal, wind-driven, and oceanic currents, spiced with a generous outpouring of mineral sediments and other nutrients from the glaciers of Glacier Bay. The result is a swirling broth of ocean that feeds billions of living things, from zooplankton to Chinook salmon. Each spring and summer, Icy Strait and Glacier Bay are a gathering place for dozens of humpback whales.

Glacier Bay National Park can be a good place to watch whales, but it is not a whale-watching destination. Within the Park, the rules for the way we behave around whales are considerably more restrictive than they are in other parts of Southeast Alaska. Before they are issued a permit to enter the Park, boaters are briefed on these special rules of Glacier Bay. For example, nowhere in Southeast Alaska can you approach a whale within 100 yards—but if you are boating in Glacier Bay, you must stay at least a quarter of a mile away. The goal is to minimize the impacts of boat traffic on whales in this very important feeding area.

One key element of whale protection in Glacier Bay National Park is the establishment of “Whale Waters”—special seasonal sub-regions within the Park that are considered especially sensitive to boat traffic. In Whale Waters, not only must boaters stay a quarter mile from whales, but they must restrict their boat speed  to 13 knots or less, and maintain a steady course in mid-channel.

Whale Waters restrictions usually start in mid-May. This year, however, with several whales already in the area, Whale Waters have started early.

It’s a good sign. Welcome back, whales.
