This is the year of Brood X, a brood of cicadas that emerges from the ground once every 17 years in our part of the world – to mate, lay eggs from which nymphs emerge, and then die, perhaps even before they are able to complete the process. The nymphs that are born drop from the trees where the eggs are laid, burrow into the ground, and they are gone for the next 17 years – to reappear once again and transform into fully grown cicadas. The cicadas are everywhere these days, and they will be gone within the next month or so. They do create a racket! We saw a lot of them last weekend on the trail near Dargan Bend.
This visit to Dargan Bend was a follow-up to a visit earlier this year. At the time of the first visit, all of our surroundings were primarily brown. This time the experience was completely different. It was green all around, although the leaves for the Sycamore seem to emerge a little later than for other trees and plants. It is also already getting warm enough for the gnats to emerge in certain sections of the trail.
We walked south from Dargan Bend, towards Harpers Ferry, the opposite direction to the one we had taken earlier this year. This was a stretch of the trail that we had not explored before.
The flowers of early Spring are gone and we are left with primarily the Rosa Multiflora, Honeysuckle and Fleabane. The American Bladdernut, a plant whose flowers we saw in April, have now fruited.I have not yet been able to identify this one new flower in the picture below. We saw it in at least a couple of places along the trail.The river is quite wide in the section of the trail close to Dargan Bend. This section is just upstream of the remains of Dam 3.We walked past an inlet lock just before remains of Dam 3.In times past, the inlet lock provided a good means providing water to the canal from the water collecting in the river behind the dam. We stepped off the trail in this section to go down to the river itself.This area of the river downstream of Dam 3 is quite rough.You can hear the roar of the river here.
We did not quite reach the bridges at Harpers Ferry, but we could see them in the distance, probably less than a mile away, from the shore of the river just beside the remains of Lock 34.To the left side of the picture above is Maryland Heights. There is a trail to the top of the cliff. We have hiked this trail a few times in the past. It is a good workout! Harpers Ferry is on the right side of the picture.
I have been thinking about the lifetimes of the cicada and what their lives mean in the grand scheme of things. They live underground (on the liquids in the roots of trees) for most of their lives, and they emerge from the ground once in 17 years to produce progeny. And then they die. That’s it! You should read about their strategy for survival as a species once they emerge from the ground. It is quite unique considering that they are consumed in large numbers by other creatures once they emerge above ground. (They are even considered a specialty for consumption by humans in some quarters. If you do an Internet search you can find a few recipes.) Do these creatures have a purpose, or is there simply an evolutionary process (or instinct!) for self propagation and preservation of the species that is in play? Is there some kind of grand plan that includes these creatures? How do human beings fit into all of this?
