Geology Picture of the Week, April 4-10, 2004: A WhereIsIt? Challenge

Too Easy

[cogitator]

I haven't done a WhereIsIt? for awhile; this one was inspired by the image at the link below the image shown. (Extra kudos to anyone who can figure out why.) No fair peeking at the page source code to get the answer until you guess!

One hint: look closely at the center of the picture.

Been there, done that.

1- please put me on your "where is it" ping list.
2- I was close, only 12,000 miles off.
3- The white building with the dome on top is a weather balloon tracking station (called a raydome). The weather people inflate the balloons in the lower portion, and a tracking device is on the roof under the dome.

Umm....is it Bullhead City, AZ? :)

[Petronski]

Uh, the html gives it away, I'd say:

I followed it here:

Île Amsterdam,
- la base Martin de Vivies

Les autres îles subantarctiques de l'océan Indien

You peeked! No soup for you!

(But you still didn't answer the question; how is the linked image related to the WhereIsIt? image?)

I don't have a list specifically for "WhereIsIt?" challenges; I do them occasionally for my Geology Picture of the Week habit. Is it OK for you to be on that list (I really only do one picture a week, and other very rare instances)?

[Petronski]

Indian Ocean? I'd suspect it's a radio relay or tracking station for the launch telemetry or imagery signals.


While we're turned the other way, they pick up the signals and radio forward. How'd I do?

A very good guess, but not correct (I think the NASA Deep Space Network antennas are in Australia; this place is too remote for the necessary equipment and support).

Since you're playing along, the relationship is geological.

Thats fine, I generally look at the gpow thread. Appreciate it.

This Picture:
I guessed the Aleutian chain, but no snow fooled me (the pix could have been taken last summer).

I just got the weather report from this site. The temp is +18 C (65 F) on a partly cloudy day. LOL

It is on the Russian weather server.

Greenland - just a guess

You're on the list.

Yes, it's quite temperate. But it doesn't get cable!

Think austral, not boreal. Someone else already posted the correct answer on location higher in the thread, but not the connection to the linked image.

[Petronski]

Well, everything I know about the place I cribbed from the html, so maybe I should just apologize for ruining the contest and move along. ;O)

French flag....

Seychelle islands?

Seychelle islands?

Correct ocean. Steer southeast (or read the answer earlier in the thread).

[Lokibob]

Geological relationship??

Is that a lava tube behind the weather station and running down to the ocean from left to right?

How would I know that?

No, you didn't ruin it; the fun part is figuring out the geological connection. Surf's up!

I don't know how you knew, but you did. Good job!

As an aside, it's very hard to find pictures of Earth- surface collapsed lava tubes, though they are numerous on shield volcanoes. I happened to know that this island had some, and thanks to the wonders of Google, I found this picture of one.

It's very easy to find either pictures inside an old lava tube (such as the famous Thurston lava tube in Hawaii Volcanoes National Park) or pictures of active lava tubes, such as the ones continually forming during the current eruption of Kilauea in the same park. But ancient collapsed tubes at the surface just look like big ruts or trenches, and aren't very photogenic. It looks to me like the one on Ile Amsterdam had a few hornitos (small lava vents) along the way to the sea.
