NORTHERN IRELAND: THE GIANT'S CAUSEWAY

 July 10, 2024

The Giant's Causeway is a geologic rock formation formed by an erupting volcano 50 or 60 million years ago. The molten basalt seeped through chalk beds to form a volcanic plateau, and as the lava cooled, it cracked, much as mud does when it dries, leaving about 40,000 mostly hexagonal interlocking stones.

According to legend, these columns are the remains of a land bridge, or causeway, built by the Irish giant Fionn mac Cumhail and the Scottish giant Benandonner so that they could meet in the middle and fight it out.  The Scottish end, which supposedly looks like the Northern Irish end, is called Fingal's Cave.


This early-19th century poem presents a slightly different motive behind building the causeway:

THE GIANT'S CAUSEWAY

They met beside the stormy sea, those giant kings of old,
And on each awful brow was set, a crown of burning gold.
No ray the yet unrisen stars, or the wan moonbeams, gave,
But far and bright, the meteor light shone over cloud and wave.

"I have been over earth to-day," exclaimed one mighty king,
"The toil of half the human race, it is a foolish thing;
For I have seen on Egypt's land, an abject million slave,
To build a lofty pyramid above their monarch's grave.

"Now let us put their works to scorn, and in a single night
Rear what would take them centuries, and nations' banded might,"
Then up arose each giant king, and took a mighty stone,
They laid the quay; they piled the rocks—ere morn the work was done.

Vain fable this! yet not so vain as it may seem to be,
Methinks that now too much we live to cold reality;
The selfish and the trading world clips man so closely round,
No bold or fair imaginings within our hearts are found.

So vortex-like doth wealth now draw, all other feelings in,
Too much we calculate, and wealth, becomes almost a sin;
We look upon the lovely earth, and think what it may yield;
We only ask for crops, not flowers, from every summer field.

The mind grows coarse, the soul confined, while thus from day to day
We let the merely common-place eat phantasie away:
Aye, better to believe, I trow, the legends framed of old—
Aught—anything to snatch one thought, from selfishness and gold.

-Leticia Elizabeth Landon (1802-1838)

The Giant's Causeway was declared a World Heritage Site in 1986. In 2005, a poll named the Giant's Causeway the fourth-greatest natural wonder in the United Kingdom.

We arrived at the visitor center and left our car in the parking lot, for which we had prepaid about $40. That included access to the visitors center (and the bathroom, which made it worth every penny).

IRELAND, DAY 5: CLIFFS OF MOHER

 July 8, 2024

A 2.25 hour drive got us from our hotel in Castleisland to the Cliffs of Moher, the #2 attraction in Ireland after the #1 Guiness Brewery Tour (which was not on our itinerary). In 2022, the Cliffs got about 1.1 million visitors, 41% of whom were from the United States.

There are two ways to see the cliffs: tourists can 1) walk along the top of the cliffs, or 2) take a sightseeing cruise. We thought we'd see more from the water than from the top, so before we left home, Bob purchased tickets (€26 each) for a boat tour. 



While we waited to board the boat, we walked around on the shore. Rather than sand, there was a rocky surface with interesting cracks filled with tiny flowers.

We boarded at about 11:45 and departed at noon for a "drive by" that took about 50 minutes.

The Cliffs of Moher run for about nine miles and rise between 390 feet and 702 feet above the ocean. At first we weren't very impressed. The cliffs were in shadow and we were very far away from them as we motored the nine miles to the far end. 

Here is a photo that I tried to edit to show the cliff details.

ECUADOR, GALAPAGOS ISLANDS: ISABELA ISLAND - TAGUS COVE PANGA RIDE AND EQUATOR CROSSING

 March 24, 2022, Afternoon and Evening

In the afternoon we took a panga trip to Vincente Roca Point, the northernmost site on Isabela Island. It is supposed to be a fantastic area for snorkeling, but the water was very murky.


I could see the great swaths of bubbles that Bob said had a soapy taste.


Close up, it didn't look like bubbles at all--more like DNA chains.

NEW MEXICO, DAY 4: BANDELIER NATIONAL MONUMENT

 June 28, 2021

I had never heard of Bandelier National Monument before this trip, and now I am wondering why. It is a fantastic place to go hiking--almost 34,000 acres (or 50 square miles) of scenic wilderness, three miles of road, over seventy miles of hiking trails, and dozens of structures built between 1150 and 1600 AD by the native Puebloans.

The area was designated a national monument by President Woodrow Wilson in 1916 and named for Adolph Bandelier, a Swiss-American anthropologist who did a lot of research in this area and advocated for its preservation. Much of the park infrastructure was completed in the 1930s by the CCC.


Our first stop was at the Frijoles Canyon Overlook (so named for the beans that grow along the creek). This is the canyon where we would do all our hiking.

We took a selfie while we still looked relatively fresh.

We made our way to the Visitors Center, where I was once again wowed by the explosion of hollyhocks.
