Natural Connections From Juneau

An eagle was soaring over the ocean as I pulled into the parking area at Eagle Beach north of Juneau, Alaska. After grabbing my camera and notebook I hurried over to the white-haired man dressed in a naturalist’s uniform of fleece jacket, hiking pants, and a big backpack with tripod hanging off the side. As I reached my hand out to introduce myself, I noticed that his beige baseball cap had a hummingbird on the front.

Bob Armstrong has written more than 27 books about the nature of Alaska. He left his studies at the University of Washington early because the brand-new Alaska Department of Fish and Game was hiring biologists. After 20 years he retired so that he could follow his own research interests.

“Do you mind if we kinda go slow along the edge here and look for crab spiders?” Bob asked as we made our way down the strawberry-blossom-lined trail. Crab spiders are one of the species that caught Bob’s interest after he retired. In one of his many investigations using his two GoPro cameras, he recorded their activities. I was happy to help him look, since I’ve been fascinated by these beautiful critters, too. Crab spiders are smooth, not hairy, and they can change slowly between yellow and white in order to camouflage themselves on their floral perch. They don’t need to build a web, because they just nab insects attracted to the flower.

Sometimes crab spiders capture bees or other pollinators—I witnessed that earlier this spring—which can be detrimental to the flower’s chance at getting cross-pollinated. On the other hand, if a flower comes under attack by a “florivore,” (an insect that eats flowers), it can pump out extra volatile chemicals—this spider’s version of the Batman Signal—and a spider may come to the rescue.

Passing by the gnarled trunk of a small alder, Bob stopped to look at it thoughtfully. After a minute I asked what he was looking for. “These are red-breasted sapsucker sap wells,” said Bob. “They are the first story in my Connections book.” Just like yellow-bellied sapsuckers in the Midwest, these colorful birds drill shallow holes into tree bark and either lap up the sap or eat the insects that are attracted to the sugar.

“The wells they drill are thought to be a critical early-season food source (both sap and small insects) for migratory hummingbirds, which may even time their arrival with that of sapsuckers,” wrote Bob in Natural Connections in Alaska.

This beautiful book, co-authored with Mary F. Willson and available as a PDF on his website:, is the reason I’d contacted Bob. I’d been tipped off that he’d written a book with almost the same title as mine, and he’d been gracious enough to say ‘yes’ when I asked if he’d go for a walk with me to talk about the natural connections of Alaska. I became even more excited to meet him once I talked with the naturalist guide Tim Hemme in Ketchikan, and Tim mentioned Bob’s books, too.

The sapsucker wells were no longer active, so we meandered out onto the gravely floodplain of a glacially fed river. The rich-brown, bell-shaped flowers of chocolate lily nodded above patches of green. Tim had given me their name, and from their color I’d deduced that their pollinators are flies or beetles. Bob pointed out bright yellow pollen dusted on the insides of the petals, and mentioned that blow flies crawl in—attracted by the scent of rotting meat to match the maroon color—and pick up those grains on the backs of their heads.

Being near the river got Bob talking about fish, and about all the observations he’s made with waterproof GoPro cameras. He’s used a dive weight to secure one into the rocks a low tide, then allowed the camera to do its magic while the tide came in. Later, when the tide was out again, Bob collected the camera. Among other things, he captured underwater images of seals playing, as well as sleeping on their sides, eyes closed.

“Do you want to see beach marmots?” Of course I did. We looked for crab spiders as we walked. Instead, I spotted an iridescent blue-green fly on a strawberry flower. Bright yellow pollen bedecked a patch of hairs behind its head. “That’s the blow fly with chocolate lily pollen,” confirmed Bob. I was struck by its beauty.

The water-washed beach graded into a thick field of grass and flowers, and those butted up against the rocks of the highway bank. We sat quietly in the sun-warmed grasses and watched the rocks for movement. Before too long, the white snout, brown face, and bleach-blonde fur of a hoary marmot poked out of a crevice, and another one scurried below. We could have watched them for hours. With the endless daylight of the north, it was hard to tell that the hour was getting late, but our watches indicated that more than a couple hours had passed.

Back at the parking lot, I thanked Bob for the walk and handed him a copy of my book. He said he enjoyed the walk too, and added “I can think of only one other person on Earth who can stroll that slowly and look at things.” It was, indeed, a natural connection.

A continuation of Ketchikan...(bonus post)

Despite only carrying my camera and a rain jacket, the Lunch Creek Trail was calling my name. I decided to forgo a backpack full of water and snacks and just hike.

The density of life was stunning. Every tree was covered in moss, covered in the climbing rhizomes of bunchberry, covered in moss, lichen, blueberry, fungi, etc. Every stump had either a little grown of blueberry leaves glowing in the peeking sunlight, or a full-on tree with gnarled roots stilting it up and anchoring it down.

The hike paralleled a river with numerous small waterfalls (the biggest falls were down by the beach.) 

The sound of water rushing and water dripping made me need to pee, of course. As I squatted off to the side of the trail I was tempted—for just a second—to use the large thimbleberry-like leaves for toilet paper. In the Boundary Waters, thimbleberry leaves are prime wilderness toilet paper. Luckily I remember in time that these plants, although having similarly shaped a leaves, are not thimbleberry. Devil’s club isn’t even related to thimbleberry, though, it’s a closer cousin of wild sarsasparilla. And, it bears spiky thorns on its stems and even the ribs of its leaves. Ouch!

I walked through huge patches of western skunk cabbage. Their crazy spathe and spadix flowers were covered with little Ocellate Rove Beetles mating, pollinating, and feeding. I also spotted two different white banana slugs—a rare color most often seen around Ketchikan (according to Bob Armstrong).  Wikipedia: “The Pacific banana slug is the second-largest species of terrestrial slug in the world, growing up to 25 centimetres (9.8 in) long,[5] and weights of 115 grams (4.1 ounces).”

The best part of my hike was when I popped out in to an opening and discovered myself in the middle of a muskeg. So many old friends to greet! So many new friends to identify!

The bright pink flowers of bog laurel were first to catch my eye.

The inrolled leaves of Labrador tea were unmistakable, although smaller than at home.

The frilly flowers of deer cabbage (a new one for me) were covered with the same Ocellate Rove Beetles and also a bee-mimicking fly. I did not see any actual bees doing the pollination up here, but this pair of beetle and fly seemed to be everywhere. This flower is in the family Menyanthaceae, related to Bog Buckbean I’ve seen in Wisconsin. It also grows in Japan, as does bog buckbean, which I did not see here.

A beautiful sedge reminded me of wetland monitoring in Maine.

A stalk of white orchids caught my eye through the green.

White flowers clearly related to marsh marigold lined the boardwalk. Later identified it as: Caltha leptosepala, the white marsh marigold, twinflowered marsh marigold, or broadleaved marsh marigold.

A new species of starflower – later identified as the Arctic starflower (Trientalis europaea L. var. europaer) also caught my eye. It grows in Scotland and Northern England as well, and is the provincial flower of Värmland province in Sweden.

Many different species of blueberries and huckleberries were in bloom all along the trail!

And I even saw round-leaved sundew on a rotting log in the sphagnum!

I heard the lifeguard-whistle-like calls of varied thrushes all along my hike, but only saw this one. It had a beak full of insects for its babies! I also heard a barred owl, with mixed feelings.

I’ve seen many little leaves and flowers that I can only guess are related to Pyrolas (shinleaf) from back home.

The bunchberry I saw had bracts that were greener than ours, and flowers that were darker in the center. It might be Cornus suecica or a cross.

Wikipedia: “Where Cornus canadensis, a forest species, and Cornus suecica, a heath or bog species, grow near each other in their overlapping ranges in Alaska, Labrador, and Greenland, they can hybridize by cross-pollination, producing plants with intermediate characteristics.”

After my hike I headed back into town, met Tim for dinner to interview him, and then watched a lovely sunset over the ocean from right down the shore from my campsite. Ketchikan is beautiful!

Catching up to a Naturalist in Ketchikan (main article)

The Tongass Highway wound north out of the remote town of Ketchikan, Alaska. To my left, rocky beaches and protected coves showed themselves through a light mist. To my right, densely forested hills climbed out of sight into the fog. Just before the northern terminus of the Tongass Highway, I pulled into the small loop road of Settler’s Cove Campground.

First I took advantage of a break in the rain to set up my tent, and then I set out for a short wander down to the beach with my camera. The cove was a stunning mix of green marsh, gold seaweed, and angular rocks washed by a river flowing out of the forest. Layers of smoky hills faded into the distance. My wandering brought me back up to the park road, where a sign for waterfall viewing along a Lunch Falls Loop Trail caught my eye.

As I hiked through this temperate rainforest of huge trees and dripping moss, the faint odor of skunk perplexed me . . . until I realized that muddy spots along the trail were dominated by lush gardens of skunk cabbage. 

Faint voices wafting through the enormous trunks of Sitka spruce and western red cedars also puzzled me, until I came around a corner and spied an all-too-familiar sight: a group of hikers standing high and dry on the trail, while an energetic naturalist sank up to his rubber-booted ankles into a mud hole just beyond. Just a couple months ago I stepped off a trail into a snowdrift for a similar purpose.

The guy looked a little younger than me, and wore an Alaska-style uniform of a flannel shirt, rain pants, and waterproof boots. “I love talking about mud puddles,” he was saying as I approached. I’m not sure how his family of four clients felt about that statement, but I was intrigued. Noticing me, he motioned to the group to let me pass. “Or,” he added amicably, “you could tag along.” Not sure if he was serious, but too curious to be more polite, I replied, “I just might do that!”

Tim Hemme, as I later discovered was his name, guides E-bike and hiking trips for the Ketchikan Kayak Co. These small group tours are a nice alternative to bus tours for cruise ship visitors stopping in port. Tim is a self-taught naturalist, and started reading books like “The Nature of Southeast Alaska,” by Robert Armstrong (who I’ll tell you about next week) just for personal edification.

Although this Missouri native came to Ketchikan on a whim, without a job or a plan, Tim soon found work on a fishing boat in Sitka. That experience only lasted 24 hours. He flew in, the boat sank (it had a hole from being parked on a rock when the tide went out,) and he flew back to Ketchikan. Now he often tends the boat for commercial divers bringing in sea cucumbers (a delicacy in Asia) and geoducks (a species of clam) by the ton. When his friend opened the guide business, Tim agreed to help out.

Still standing in the puddle, Tim went on to explain that water-soaked soils, paired with the acidifying action of sphagnum mosses, create enormous patches of muskegs as you go inland from the coast. In these cold, acidic, oxygen-poor environments, the decomposition rate slows to almost nothing. In the Northwoods, of course, we call these bogs (or maybe poor fens if you want to get technical.)

On the other hand, the lush upland forest adjacent to his mud puddle (just the tip of a muskeg, he explained), exhibits an extraordinary rate of decomposition. The huge trunks of fallen trees are soon broken down into rich, brown sponges, and seedlings use them as nurse logs and nurse stumps to begin their tiny lives. Water-soaked lichens fall from the canopy and their decaying bodies return nitrogen to the soil. Muskeg vs temperate rain forest: these water-soaked neighbors have their differences.

As we climbed out of the small hollow, the twisted trunk of a giant tree caught someone’s eye. Tim explained that this was a western red cedar. The fibrous bark definitely reminded me of northern white cedars at home, and craning my neck I could see the cedar’s fans of lace-like needles silhouetted against the bright gray sky. The split-open trunk revealed the tree’s twisted grain. “Western red cedars are better than any other tree at withstanding high winds,” commented Tim. “Their spiraling grain allows them to load up the wind’s force like a screw, and then spring back. Load up; spring back. It prevents them from just falling over.”

We eventually popped out at the beach, and Tim stopped to stare thoughtfully across the ocean. “You have to know what you’re doing to take a boat through the passage,” he advised. “Irregular spires of shallow rocks mean that at high tide you’re fine, and at low tide you’re sunk.” Tim didn’t tell his clients the story about his first experience on a fishing boat, but clearly that was on his mind.

All too soon we reached the end of the Tongass Highway where the group’s E-bikes were parked. I thanked them for letting me tag along and turned back toward the woods. Skunk cabbage, cedars, bogs, and a naturalist: I was giddy from the combination of familiar friends and a spectacular new place.

Arriving in Ketchikan, Alaska (a bonus post)

After my beautiful walk in Bellingham, WA, where I saw the barred owl eating crayfish, my adventure truly began. I boarded the MV Columbia ferry and entered the Alaska Marine Highway System. After duct taping my tent to the bridge deck, I explored all four decks passengers are allowed on while the boat is in motion, and then settled in for a two-night cruise.

Thickly forested hills spooled by on either side. Porpoises leaped from the water, and a few pairs of orcas swam by. Meanwhile, I made myself comfortable on the green fake-grass carpet under the heated greenhouse roof of the solarium, and made friends with four other young women traveling alone. I had my tarot read by Rachel—a journalism major going to do a radio internship in Sitka. I chatted with a bright-eyed girl on her way to do an internship with the bears. And I listened sympathetically to a broken-hearted doctor heading to start a new practice in Juneau.

I used the hot water spigot on the cafeteria’s coffee maker to make oatmeal in the morning, and did the same with ramen for dinner. I also rolled out my yoga mat under the solarium in order to work out the kinks of travel.

When the ferry docked in Ketchikan, Alaska, at 7:00 a.m. in the rain, I was sad to depart. But, when my feet hit the ground, Hawaii became the only state I have not visited!

It had taken me several hours of the ferry ride to realize that the changing colors of the shoreline were caused by the tides going out and coming back in. A thin line of black rocks near the trees expanded into a rich gold band of seaweed, and lush, green saltmarshes appeared in low areas. Now, fully aware of my proximity to an ocean (it took a while for that to sink in!), I was excited to see that my arrival in Ketchikan coincided with a low tide.

Driving north on Tongass Highway, I spotted a rocky beach through the trees, and pulled in to the Refuge Cove State Recreation Area. Clambering around on the rocks, I soon spotted purple and orange ochre stars, slimy red-orange sea cucumbers, and spouting butter clams. I recognized the green-striped tentacles of burrowing anemones from the education tables in the ferry’s cafeteria. I also found an odd creature that Tim later helped me identify as a hydroid.

Twisted trees created a magical world just inland, and the starry white flowers of False Lilies-of-the-valley (related to the one in the Northwoods) created a beautiful border between beach and forest. A break in the clouds and lifting of the persistent drizzle urged me on toward the campground so I could dry out my tent.
