Now we have a (relatively) firm timetable for arrival at Victoria - a month, I think it was - I thought the time was right to open a new thread on what will greet us when we get there. So, I've been playing about (cue groans from the more experienced image processors! ) with the best Victoria image I could find, and have brought out some interesting features and details I'd appreciate people's comments on, preferably not in Klingon, as I'm still just dipping in and out of my geological dictionary...

I've got three "areas of interest" for you, labelled here... Victoria Crater

1. Spills of boulders and slumping along the northern crater rim and detail on the "Boat Ramp"?

2. Pronounced gully-like feature on western slope?

3. Large shelf on south-western edge?

I hope no-one will criticise the very amateurish effort here, or think I'm putting these images forward as anything special. I'm just trying to get some discussion and debate going. I know this is a less than scientific exercise - I leave the science to you guys, I just like to throw a pebble in the discussion pool and watch the pretty ripples spread out...

Greetings Areologists,

I've been lurking here for a long time now. Last week I happened to drive by Brent Crater in Ontario and got a quick digital camera mpeg of it I thought some of you might enjoy given the recent postings about terrestrial craters. Warning, the video file size (1.75 megs) and the images linked below are a bit large for some bandwidths.

Brent was formed by an explosion equivalent to 250 megatons of TNT 450 million years ago, and is approximately 4 kilometers wide.

You can read more about Brent here: http://www.valleyexplore.com/walk/ottawa/brent.htm

The video was taken from the observation tower shown in the valleyexplore link. I also braved the black flies of the nature trail down to the floor of the crater and saw some composite rock the brochure said formed at the base of the cliff when the ancient crater cliff wall eroded. The crater floor included some strange alien looking plants. The impact excavated to a limestone layer giving the water on the crater floor an unusual chemical profile, and I suppose that might explain the plants.

As you may imagine, the whole experience made me think of Victoria.

Thanks to everyone for making our Mars adventure so much more interesting and enjoyable!
