Minute Man National Historical Park

No big vacations this summer, but we did a couple day trips. First off, we headed back to the American Revolution at the Minute Man National Historical Park in Concord, Massachusetts. We first stopped in at the visitor center, where we were just in time for the multimedia extravaganza1 put together by the National Park Service about the events surrounding the Battles of Lexington and Concord that began the American Revolutionary War.

1 It was a video, with multiple screens, some lighting, and a light-up battle map.

To summarize, British troops stationed in Boston had orders to take action against the colonial militia, the goal being to disarm then and capture rebel leaders. The colonists were aware of these orders and when the British regulars began to move out from Boston, Paul Revere and William Dawes were sent out to warn and muster the militia, Revere crossing the Charles River and taking a northern route while Dawes rode south down Boston Neck. Revere also passed along the message that the regulars were leaving Boston by boat to the Old North Church so they could signal Charlestown using lanterns (the “one if by land, two if by sea” from Longfellow’s poem). At Lexington, Revere and Dawes met up with other leaders and decided that Concord, the site of military stores, was the target of the British. They rode on, joined by Samuel Prescott, then ran into a British patrol. Revere was captured, Dawes was released but lost his horse, and Prescott evaded the patrol and made it to Concord.

Because of the warning they had been given, militiamen were waiting for the British when they made it to Lexington at sunrise of April 19, 1775. During the encounter, someone fired a shot, leading to a brief skirmish that killed eight Americans. The British continued on to Concord, where they met a larger group of militiamen. The armies faced off at the North Bridge, where a British soldier fired first, initiating volleys from both sides (Emerson’s “shot heard round the world”). In the end, several British soldiers lay dead, and the regulars began their retreat to Boston. Throughout the rest of the day, more militia joined the growing Colonial forces as they chased and harried the British troops along the way.

Hartwell Tavern

After refreshing my U.S. History I knowledge, we set off along the Battle Road Trail, an approximately 5-mile long trail that follows some of the original route the Colonial militia and British regulars travelled between Lexington and Concord. Along the way, historical points of interest include houses belonging to militiamen and their families, battle sites, and Hartwell Tavern, a gathering place for the colonists. At Hartwell Tavern, we stopped to hear a program about the Colonial militia/minutemen where we got to see a musket fired (if you were fast and well prepared, you could fire three whole shots a minute). We also saw sheep, pigs, and planes (the park is south of Hanscom AFB). The Battle Road trail isn’t paved, but it’s mostly flat dirt and can be biked, which a good number of people were doing. The trail runs east-west with the visitor center at the east side and Meriam’s Corner, where the regulars’ retreat turned into a running battle with the minutemen, at the west end. In general, the east side of the park is more wooded while there are more open fields in the western half.

In the end, it took us about 4 hours of walking to cover the ten miles out and back of the trail, though we were in the main section of the park for a total of slightly over 6 hours, including our initial stop at the visitor center and later breaks at Hartwell Tavern and for snacks. As of our visit, there was no fee to enter the park. To finish off the day, we drove to the North Bridge, in an unconnected section of the park, to see the bridge and the Concord River before heading home.

Odds and Ends

Before leaving Ann Arbor, besides wrapping up as much research as possible and more or less packing up most of my belongings, I went for a few final adventures around town. I got to experience a last spring season and see the wild violets, bloodroot, dandelions, daffodils, tulips, trillium, wild geraniums, etc. bloom. Despite telling myself I wouldn’t, and that 250 mm (400 mm field of view full frame equivalent) isn’t that much zoom, I went bird watching with my camera to catch the spring migratory season, featuring red-winged blackbirds, robins, grackles, mourning doves, great blue herons, and more. There were also plenty of squirrels like always, plus rabbits (eastern cottontails), baby geese, a beaver, a painted turtle, and mating snapping turtles.

I baked cranberry orange scones, molasses cookies, and cranberry apple bread to use up ingredients in my freezer and pantry and celebrated warmer temperatures with courtyard lunches at the office. During my usual perambulations I discovered one weekend that Traver Creek had overflowed, flooded some of the trails, and washed out a wooden footbridge. In honor of Star Wars day, I put together a mini Lego Millennium Falcon that I added to an online order for free shipping. For the first time since Covid happened, I went to a library program, on how to birdwatch with the Washtenaw Audubon Society (sidenote – the first book I borrowed from AADL was Emily St. John Mandel’s Station Eleven; the last: Star Wars: X-Wing: Wedge’s Gamble by Michael Stackpole).

My lab had a celebratory barbeque/game night party at our advisor’s house for a few of us who were going to leave Ann Arbor soon (we ended up holding four dissertation defenses in just over six months). I also tried to meet up with some friends that I hadn’t gotten to see much during the pandemic times. One of those meetings was when I saw the mating turtles. Another time a friend and I biked downtown to play arcade games (including both Star Trek and Star Wars pinball and skee-ball) at Pinball Pete’s and drink a quart of sangria at Casa Dominick’s. Finally, our lab plus friends met up at the best (and only) bar on North Campus for after work drinks one last time.

Right before I moved my parents and I spent a day downtown returning my office key for the $5 deposit, visiting U-M’s Museum of Natural History and Museum of Art, and spending my M-Den gift card. And that was some of my last months in Michigan. Until next time, Ann Arbor.

Tulip Watch 2022

Going back to before I moved from Ann Arbor for a quick look at how the tulips fared this year. As I’ve mentioned before, someone who had the apartment before me planted tulips at some point. Without me doing anything at all, they keep coming back each year, and may possibly be spreading, or it could just have been a good year for them this year. Sometimes they get eaten by deer before having a chance to bloom, or last year they were unceremoniously mowed down shortly after blooming (I rescued the less mangled flowers, stuck them in a jam jar, and brought them into the apartment), but this year I had just under two dozen tulips bloom.

I took my telephoto lens out for a spin on a few separate evenings to take advantage of the shallow depth of field on the lens and the softer light of the declining sun. Without getting into an optics discussion, given a particular focal distance, a lens with a longer focal length has a shallower depth of field. For example, if you’re taking a photo of a flower two meters away with a Canon Rebel T6, at an aperture of f/5.6, an 18 mm wide angle lens has a depth of field (DOF) of 4.63 meters (0.79 m in front/3.84 m behind), a 55 mm focal length has a DOF of 0.28 m, and a 250 mm focal length has a DOF of just 0.01 m. Of course, the wider the focal length the more you have in the picture besides the flower, but generally speaking, using a longer focal length decreases the depth of field and increases the separation between your subject and its background. That said, here are the tulips.

Cuyahoga Valley National Park

On our long drive back east, we passed right by Cuyahoga Valley National Park in Ohio, so we had to make a quick stop for a hike. The Cuyahoga Valley is located between Cleveland and Akron and the Cuyahoga River is famous for, among other things, catching on fire. This happened at least 13 times, and the June 22, 1969 fire helped to bolster the beginnings of the American environmental movement. In 1974, the Cuyahoga Valley was designated a National Recreation Area, then on October 11, 2000, was made a national park.

Boston Mill Visitor Center

We didn’t have much time at Cuyahoga, and the one hike that you do if you only have time for one hike at Cuyahoga is the Ledges Trail, which is what we did. If the parking lot at Brandywine Falls wasn’t closed, we might have also tried to sneak in a glance at a waterfall, but that wasn’t in the cards for this visit. The Ledges Trail is a 1.8 mile loop that circles a plateau of rock formations. The trail network around the Ledges Trail also includes several cut-through trails and side trails that connect to other areas of the park. The trail is primarily dirt and rock, with rock steps in several places. Along the way, you walk at the bottom of and between rock cliffs that are fun to explore but difficult to fully capture in photos.

Ledges Trail

The trail passes by a cave, but to protect the bats there from white-nose syndrome, caused by the white fungus Pseudogymnoascus destructans that can decimate bat populations, the entrance was barred. There’s also an overlook, the Ledges Overlook, that didn’t seem to be overlooking anything of much significance. Especially in late spring and summer with the trees filled with leaves, you mostly just see a lot of trees with leaves. The rest of the trail makes up for It, however. And as we were nearing the end of the trail, we spotted a barred owl, out in the evening, our first time seeing an owl in the wild.

Cuyahoga Valley National Park is slightly unusual in that it can almost be described as an urban national park, with 4 million people living within a half hour drive of the park. Parts of the park either abut and/or are managed by Cleveland Metroparks, Summit Metro Parks, or private owners. Besides the ledges, it contains waterfalls, wetlands, ravines, forests, and more. The Cuyahoga Valley Scenic Railroad goes through the park and offers scenic railroad rides throughout the year. There is no fee to enter the park, though we still made a quick stop at the Boston Visitor Center to talk to the park ranger, and pick up a map and stamp. There’s plenty we didn’t get to see in the park, so we might be back if we’re ever in the area, though I also still have about 400 (of 423) National Park Sites and hundreds and thousands of state and local parks to visit.

Notre Dame

Because of transportation scheduling, instead of dropping my brother and his girlfriend back off in Kalamazoo, we made a further detour to South Bend, Indiana for them to catch a train there. On our way south from Glen Arbor, we first made a stop at the Point Betsie Lighthouse. It was closed, but we weren’t trying to take a tour anyway, so we got a few photos and moved on. We reached South Bend in the late afternoon, with some time to look around Notre Dame.
 
Point Betsie Lighthouse

Notre Dame was founded in 1842 and covers 1,261 acres in Notre Dame, IN outside of South Bend. As of fall 2020, they had a total enrollment of 12,700 students, split 8,700 and 4,000 between undergraduates and graduate students. The school was not officially coed until 1972, though women had received (mostly religious) degrees from Notre Dame since 1917. Their sports teams compete in the Atlantic Coast Conference (ACC) except for football (unaffiliated) and men’s ice hockey (Big Ten).

The major landmarks on the Notre Dame campus are probably the football stadium, the Basilica, and Touchdown Jesus (actually called the Word of Life). We did not go into the football stadium, the Basilica was closed on the afternoon we were there, and we did get to see Touchdown Jesus. After walking around for a while (and passing by the ChemE building), we went into the Duncan Student Center, next to the stadium. This was a really nice building with dining options, study spaces, a climbing wall, and a track and gym. I’m still kind of mad at Michigan for closing their climbing wall right before I started there and planning to build a new one after I left. We had an early dinner, then had to drop my brother and his girlfriend off at the train.
 
Basilica

Because we wanted to see the inside of the Basilica, we returned to Notre Dame the next morning before leaving Indiana to head back to Ann Arbor. It was an impressive building, filled with statuary, murals, stained glass windows, and an organ. Since we were on campus, we also stopped by the Snite Museum of Art. The museum was pretty typical of a university art museum – not huge, but they had a decent variety of paintings, sculptures, painted plates, gilded cups, etc. ranging from 16th century European oil paintings of earls and counts to modern art.
 
Touchdown Jesus

Notre Dame has a pleasant campus, though it seemed rather abandoned, even for summer (graduation was the week before, so the undergrads might not have returned for summer activities yet and the grad students were probably locked in the basement). Everything was also fairly well contained, with grassy quads, tree-lined paths, and few road crossings to get run over at. There was what looked like a nice commercial block with restaurants, shopping, and lodging just south of campus, though we didn’t walk there. Otherwise, the surrounding area seemed to lack the natural areas and hiking trails of Ithaca and the larger variety of restaurants, stores, theaters, etc. of a bigger city like Ann Arbor. I’m not sure I would have wanted to go to college there, but campus was nice for a visit.
