And on the 900th stroke, we arrived at East Cape. We were greeted by a family of campers in a motor boat that gave us first pick of a camp site out of deference to our muscle-powered wake, and a flock of Sanderlings.

By 4:45, we had set up our tent. As the day faded into night, we passed the time cooking, arranging seashells in the sand, chatting, sipping bourbon, and star-gazing. As the night wore on, the stars grew brighter and brighter, the rising and receding tide lapped against the shore twenty feet away, and giant wading birds stopped to sample insects outside our tent.

Gauthier woke up early to watch the sun rise.

Our friends the Sanderlings were up early as well, as were a flock of Terns. During low tide, the shallow bay reveals muddy tongues protruding from the shoreline that are completely hidden during high tide, like the one these Terns are on.

One characteristic that all of the beaches we stopped at had was washed up sea sponges. There are over two hundred sponge species in South Florida. The sponges in the photo below are vase sponges.

Sea sponges are a foundation species and a sign of a healthy ecosystem. In the photo below, a Sanderling inspects a Haliclona rubens.

Marjory Stoneman Douglas had a hard time making a case for the designation of the Everglades as a National Park. Folk saw holes in trees like the one below, assumed they were created by insects with really big teeth, and wanted nothing to do with it. Honestly, we wondered whether that hole, with its serrated edges, wasn’t created by giant, razor-sharp mandibles.

P1000862_1200

Holes in shells like those in the shells in the photo below provide clues as to how the shells died. Those tiny perforations were caused by sponges called Boring sponges. Boring sponges attach to shells for shelter, often smothering the host. The little holes are caused by the chemicals they use to attach themselves. Polychaete worms are the villains that cut grooves in oyster shells. And the little holes that are useful for turning shells into necklaces, those are caused by predatory sea snails and slugs.

Gauthier paddled to the southernmost beach on East Cape. The wind had picked up and was blowing from the east at a worrisome clip, so I chose not to accompany him and preserve my energy.

There he saw Gumbo limbos…

and this giant Horseshoe crab. This lovely lady was around two feet long from head to tail! She should scare me because horseshoe crabs are more closely related to spiders than they are to crabs, but seen from above she’s not very scary-looking. You have to respect a species that’s been around for more than 300 million years!

P1000899_1200

As we headed eastward towards East Clubhouse Beach where we were to spend night two, we paddled against the tide and a wind of around 18-20 mph (8-10 m/s). We used the tree below, which marks the southernmost tip of Florida, to gauge how far we’d traveled. It grew smaller very slowly.

Cape Sable, the southernmost point of Florida, had been on our “To Kayak” list for about three years. The promise of Roseate spoonbills, American crocodiles, Florida gopher tortoise and Smalltooth sawfish, combined with the challenge of a 23 mile round trip ocean paddle, and the lure of secluded shell beaches made this an adventure worth working towards. This year we were ready.

P1000732_1200

Gauthier had assembled a not unpraiseworthy collection of lightweight camping gear and we had improved our paddling skills and built up enough muscle and endurance to meet Florida Bay’s challenges. Currents, tides, winds, sun, and mosquitoes, we were prepared for them all. Ollie, unfortunately, had demonstrated that ocean kayaking was not his thing, so he stayed behind with his duncles and daunties (dogspeak for doggie uncles and aunties).

P1000740_1200

Our plan: Saturday, February 13, we would paddle 11 miles from Flamingo Visitor Center to Cape Sable. Sunday, we would paddle about half way back to East Clubhouse Beach. And Monday we would paddle the remaining five or six miles back to Flamingo Visitor Center.

We arrived at Flamingo Visitor Center just as it opened at 8 AM to pick up our back country pass. During the ranger’s protocols speech,  we were surprised to learn that we would face gusts of up to 25 mph on our return trip, something the forecasts of the previous day, which specified maximum gusts of up to 15 mph, had not mentioned. Somewhere in the back of my mind a voice said, “Should we postpone?” but my unhesitating response to the ranger was “I guess I’ll be getting more excercise than I bargained for!”

P1000751_1200

The mosquito condition was described as “moderate,” which is not bad by Florida standards so long as you use repellent (and not the Whole Foods brands, the real stuff) and have your tent set up before dusk, which is when they come out in force. We planned our paddle out to coincide with high tide. As the Bay drained, it carried us out towards the Gulf. We paddled against a north wind of around 10 mph, but it was easy going overall.

P1000755_1200

We had lunch at Clubhouse Beach, named for a clubhouse Flagler or another developer had wanted to build there many years ago, despite the freshwater marshes, marl prairie, saltwater lagoons and mangrove swamps.

If you liked making mud pies or walking barefoot in the rain as a little girl or boy, you may appreciate Florida Bay mud. The sensation of Florida Bay mud squishing between my toes is something I am unlikely to forget. The shallow Bay and receding tide meant anchoring our kayak in the mud and walking to shore.

P1000756_edited_1200

Dimples in the mud near the shore were filled with shells. Angel Wings, Angulate Wentletraps, Antillean Nerites, Atlantic Distorsios, Atlantic Slipper Shells, Calico Scallops, Cancellate Cantharus, Common Bubbles, Common Nutmegs, False Drills, Fan Scallops, Flame Augers, Florida Cones, Florida Fighting Conch, Florida Rock Shells, Fly-specked Ceriths, Golden Banded Cones, Lion’s Paws, Muddy Ceriths, Periwinckles, Rose Petal Tellins, Sanibel Drills, Top Shells, Turkey Wings, we saw them all! After three or four hour’s paddling, there’s nothing more relaxing than arranging shells in the sand.

Sea pork: there is such a thing and if you venture out to Clubhouse Beach you just might see it. Sea pork is a small glob of cellulose that once housed zooids. Zooids are “a colonial animal that can survive only when connected with other zooids. Each has its individual personality, but collectively they exist as a single being with a shared goal of survival” according to an article in The Guardian (http://www.theguardian.com/environment/gallery/2013/oct/12/portuguese-man-owar-photography).

The Red mangrove below lent us its shade. I can never get my mangrove types straight, but here is a slice of mangrove wisdom from Florida International University: “Mangroves must survive the stresses of flooding and salt in the estuary. Red mangroves have prop roots that increase oxygen uptake and line the banks of keys and rivers in the Everglades. Black mangroves exude salt from their leaves and both red and black mangroves are well adapted to salinity changes” (http://fcelter.fiu.edu/education_outreach/Virtual_hydroscape/mangroves/?selected=fringe_mangroves).

After an expertly crafted meal (Gauthier does love camp cooking), we paddled onwards to East Cape, the easternmost and closest of Cape Sable’s beaches. At MicMac Canal (below) we counted 900 strokes to East Cape.

The endless blue sky and mangrove coastline allowed undulating thoughts of work and family to creep into my consciousness. Mangroves transformed into excel spreadsheets, the blue sky transformed into birthday cards, and the sunlight sparkling on the water transported me to a Brownie Guides meeting, Adelaide, Australia, circa 1990… Five girls in brown uniforms seated cross-legged on the floor around a container of silver glitter and a bottle of glue… The container of glitter falls over and ten hands quickly sweep it up before their leader, Lutana of the Moora Mooras, can find out… Five exuberant girls stand in a ray of sunlight, watching their arms and legs sparkle.

Cayo Costa State Park

My beloved boyfriend took me to Pine Island and Cayo Costa State Park for my birthday. I couldn’t have asked for a better birthday present.

That thar is our handsome inflatable Advanced Elements tandem kayak. It's parked on top of an island made up of crushed oyster shells. The oysters served at the restaurants on Pine Island are fantastic! No wonder the Calusa had the highest population density of south Florida! The Calusa were Native Americans who inhabited the coast and inner waterways of Florida's southwest coast as far back as 500 CE.

And there's Ollie in his jersey; cute and functional, it prevents him from getting covered in sticky burs. See all the oyster shells!

I love knicker nuts, which is what you're looking at in this picture. Inside those spiky shells are incredibly hard, heather-grey nuts, roughly spherical, striped, about an inch in diameter. They're used in jewelry in the Caribbean. If you crack them open with a hammer, you see that the shell is made up of multiple layers and you find a flat, round white seed inside.

We had a picnic lunch and this way our view; it's Boca Grande.

The light wasn't great, so I had to doctor these pictures. Here I tried to enhance the light glistening off of the water. See the hungry little plover?

Sea Oats, so important to barrier island ecology.  Picking or disturbing sea oats is punishable by fine in Georgia, Florida, and North Carolina (according to Wikipedia). Just visible in the background are the fuzzy tops of sable palmettos. Sable Palmettos provide homes for all kinds of interesting critters.
