Impact structures in Sweden

[Astrofriend (Lars)]

Hi,
We have been on trip to Northern Sweden this summer. Among other things we visited two meteorite craters, Dellen 20 km and Siljansringen 51 km. I have written a small report about those visits here.

Dellen:

Siljansringen:

Both of them are one of the best preserved and big impact structures in Europe and it's easy to visit them.

They are amazing photographs Lars. The view from that tower was spectacular and it's nice to see someone isn't getting drenched, LOL
I'm trying to remember which old American movie featured a crater which isn't full of water, maybe Starman, I can't remember. It seems natural with the lower impact areas water would collect and fill them in.


Ah, it was indeed the 1984 release of Starman:

Originally named Canyon Diablo Crater, it was created about 50,000 years ago. Impact speed was estimated to be around 29,000 mph. Impact energy has been estimated at about ten megatons. It's roughly 3,900 feet in diameter and 560 feet deep. It's privately owned by the Barringer Crater Company. In November of 1967, it was designated a National Natural Landmark. At the time of my visit, the cost to visit the crater was $22.00 for adults.

Really enjoyed these photo essays of the 2 impact craters, excellent photos and descriptions and nice weather from the looks of the blue skies and calm waters. Thanks for sharing your astro travels with us.

Hi Jeff and Leo,
Thanks for the nice comments.

ps.
At the end is an update, a link to the complete Northern Sweden trip if you find it interesting.

Very interesting, Lars.
Thanks for sharing.

Hi Pierre,
I think you even more impact structures in Austarlia. They are big and hard to see from the ground. I remember one I read about, the Spider crater.

WOW, I'd not even heard of the Spider crater Lars, thanks for mentioning it.
It's way too far for me to go see.
I don't know if you know much about Australia but there are vast distances between places over here. One day at Central railway station in Sydney a couple of European tourists got off the same train as myself and asked if I could point them in the right direction to Perth (also in Western Australia), they had all of their hiking gear and thought it was going to be a few hours hike.

The Perth to Sydney drive is 3,932km in distance, and takes 41 hours

I explained they wouldn't be walking it in a hurry, they appeared quite shocked too when I explained it was around 4,000 kilometres.

I found a link to the Spider crater:

I have seen a lot of documentaries about Australia and know the Swedish trucks Volvo and Scania deliver truck trains to your country. Big space to drive around.
