Circumnavigating Angel Island, San Francisco Bay

10am - Pull into the parking lot at Horseshoe Cove. The view from the Cove is pretty great. This morning the Bay was covered in a thin layer of thick fog, up to the base of the GG Bridge. It cleared up as the day went on.

Thanks to its strategic location just inside the Golden Gate, Angel Island has quite a bit of history. It was the U.S. immigration station from 1910 to 1940 where hundreds of thousands of immigrants entered the country. In the 1950's and 60's it was a missile site. In 1954 the park was transferred to the California State Park system for everyone's enjoyment! Today you can camp, hike, bike, and do many other fun things on the island.

This was another BASK (Bay Area Sea Kayakers) paddle, and apparently this was one of the biggest groups they'd ever organized - I guess there were 52 boats at one point! It didn't feel so big because we broke up into pods of ~10 boats each, based on speed. 

My pod was pretty pumped to get to Angel Island speedily, so I really had to focus on sitting up straight and paddling like a true Greenlander to keep up! We paddled out of the cove and around the point and north along the coast, at which point we re-grouped and paddled straight across the 2-mile channel as a group. There was almost no wind, and the sun was shining - pretty spectacular conditions for the Bay. 

Everyone convened for lunch on Quarry Beach, which is on the east side of the island. We shared a potluck lunch with an obscene amount of delicious desserts. 

We continued our counter-clockwise circumnavigation of the island on the return trip. The tides had picked up some speed, and the wind was blowing (more typical for a Bay afternoon). These things made the trip back a bit more adventurous, but still nothing too intense. On the way back I met a couple other young paddlers, and we did some impromptu rolling practice when we got back to the harbor.

Drakes Estero, Point Reyes National Seashore

Estero: "small river," "marsh," or "estuary" in Spanish. I looked it up before agreeing to go on the trip. "Drakes" because it's the likely landing spot of Sir Francis Drake in 1579 during his circumnavigation of the world (thank you, wikipedia).

Drakes Bay Oyster Company

We departed from the Drakes Bay Oyster Company around 10am. The Oyster Company manages a pretty extensive network of wooden racks with oyster beds throughout the Estero - when the tide reached a certain water level, we kept scraping the bottoms of our boats on wooden poles just below the surface. There's a lot of controversy surrounding the company -- oyster collection disturbs seal pups, covers eelgrass beds, and leaves some plastic waste floating around the estuary.

On the way out towards the ocean we turned left into Home Bay, where we discovered a number of bat rays, leopard sharks, jellyfish, and harbor seals. It was my first time seeing a shark from my kayak. Apparently they're harmless to humans, which makes this slightly less exciting. They eat clams, shrimp, worms, and other non-human things. They're native to the west coast (from Mexico to Oregon), and can usually be found in pretty shallow water. Here's what they looked like from my viewpoint:

Leopard sharks - so pretty! Source

The lunch destination was "Limantour Spit," which is the narrow strip of beach that almost cuts the estero off from the greater Drakes Bay (a wide bay on the Pacific Ocean, just south of Point Reyes). The Spit was covered in white Pelicans:

According to this writeup by the USGS, the unique shape of Point Reyes, which extends approximately 15 km out from the coast, often made it too difficult for ships to sail far enough west to get around the point. Ships often ended up shipwrecked and stranded in Drakes Bay.

Before the 120 meters of sea level rise that occurred over the last 18,000 years (woah), Drakes Estero was just a river valley, which is why it has such a unique shape. It's sometimes said that it looks like a hand, with Limantour Estero to the east as the thumb (see map below). Today the freshwater inflows from the minor creeks are very small compared to the tides and currents flushing the Estero twice-daily.

The sand barrier (Limantour Spit) that builds up in front of the Esteros is created because the prevailing sediment transport moves from south to north along the coast. Since most of the waves reaching California come from the Pacific Northwest, the waves bend around Point Reyes and end up reaching the beach from the south (kind of counter-intuitive), eroding the sandy cliffs from the south end of Drakes bay. The waves push the eroded sand up along Drakes Bay, where it ends up on the beach.

Phew, ok enough nerding out...

Fighting the Tide at Elkhorn Slough, Monterey Bay

[blog post interrupted by random clippings from Marika's trip summary!]

In June. Marika, Julia, Whitney, and I decided to go for a paddle in Elkhorn Slough. This was shortly after I found out my company was applying to work on a restoration project for the slough. In 1947 a harbor was built at the mouth of the slough to provide a safe haven for boats coming in and out of the slough. Unfortunately, constructing a permanent structure like a harbor limits the slough's ability to naturally manage itself by opening, closing, and moving north to south, depending on factors like inflows and sediment supply. Since 1947 the slough has experienced massive erosion - even when we were there we could see big chunks of the marsh falling into the channel. Keeping the mouth of the slough wide open makes it so that the water moves in and out with the tide more quickly than it otherwise would. This makes sand and mud move back and forth more quickly. On the ocean side of the slough is a huge submarine canyon:

This canyon is like a big sink - much of the sediment that comes out of Elkhorn Slough falls into the canyon and doesn't come back. I found out recently that my company will be working on the restoration project (that I'll be helping to manage!), which will look at different options to try to fix this problem. Getting rid of the harbor isn't really an option, so the main focus will be on importing sediment from other sources (to be determined) and placing it upstream in the slough to try and counteract erosion. The project is just starting, so more info on that later!

Pickleweed! One of the main marsh plants native to California. It turns bright red in the fall, so it almost makes it feel like there are seasons here. I tried chewing on it... it tastes like grass, which was a huge relief considering my disagreements with pickles.

Some sea lions chilling out in the marsh. In the background are the cooling towers from the Moss Landing Power Plant, a natural gas-driven electricity generation plant. The plant takes cool water from the slough or ocean and uses it to cool the gas turbines. The warm water gets dumped back in the ocean.

Happy Julia! Here you can see how quickly the marsh edge is eroding. 

Seagull hanging out above the pickleweed. Everyone in CA hates seagulls because they're invasive, but they're still fun to take pictures of because they're not very scared of people... :)

The slough is full of jelly fish. We tried to pick them up with our paddles and toss them at each, but gravity is not their friend, so they ended up being 2D instead of 3D. It was a little gross, so we stopped. "We passed by a cow farm with manure sliding down a hill into the water...nasty smell." - Marika

While the slough is known for it's excellent sea kayaking, it's also known for intense winds and fast moving tides, that can combine in the afternoons to make for tricky returns to the harbor. The wind was pretty strong on this day, so it took us at least two times longer on the way back to the kayak shop.

Playing in the Surf Zone at Pillar Point, Half Moon Bay

Feeling somewhat intimidated by the Pacific Ocean, I signed up for a Surf Zone class by California Canoe and Kayak. It's a paddling shop with a number of locations in the Bay Area, including Oakland (about 5 mins from my house) and Half Moon Bay. 

I was one of three students in the class. According to the instructor, the surf was perfect for learning. The class was focused on handling your kayak in the surf zone: launching and landing safely, punching through breaking waves to get out past the surf zone, and side surfing to avoid getting flipped when the waves turn you sideways. I'd practiced most of these things on Lake Ontario and at Sea Kayak Georgia, but the waves on the west coast are different: the waves were more frequent and the beaches are steeper, making the waves break differently. AND I was severely out of practice, so it was a very useful class! 

We paddled out past the breakwater and around to the east where we practiced playing in the surf zone. I swallowed an enormous amount of salt water the first few times I rolled, which made for quite a nauseating afternoon. Once we were completely exhausted from paddling out through and into the surf, we paddled along the breakwater to some bigger waves breaking on the offshore reefs off Pillar Point. Just north of here is where Mavericks breaks. The huge waves only break here for certain long period swell, so of course we weren't attempting to paddle in 25 foot waves that often break here. It was still cool to be so close though... 

I didn't get any great pictures since I was trying to pay attention, but here's one of Pillar Point,  facing NW. You can sort of see the waves breaking in the distance. 

After class we relaxed at the kayaker-friendly yacht club and had a beer while de-briefing the day... Perfect weekend day!

Canoeing the Sudbury River

My little brother's high school graduation in June brought me back to Boston for a long weekend. As usual, my visit home provided my mother and stepfather the opportunity to ask boat-related questions and favors. Last time it was "can you help us buy canoe paddles?" This time it was "can you fix the canoe seats? My brothers and I spent an afternoon measuring and drilling holes in the new canoe seats, bringing the old green canoe back into service.

Moeke (= "mom" in Flemish) and I took the boat on it's maiden voyage, version 2,  down the Sudbury River near our house in Lincoln, MA. Here's a map:

To be honest, it's been so long since we did this short paddle that I can't remember much more. Oops. But here's my mother in her funny hat :)
