Talk:2985: Craters

Delaware/Pennsylvania Arc

The Delaware/Pennsylvania arc is a circle, sure, but so is every other allegedly "straight" line on the map. The 49N parallel looks like a straight line on some projections, but a polar projection shows that it is clearly a circle around a point on the Earth's axis. The Delaware/Pennsylvania arc is only unique for NOT being aligned with the axis. 172.71.102.20 19:07, 13 September 2024 (UTC)

The "Delaware/Pennsylvania arc" has a long and juicy history. Not a circle. Twelve-Mile Circle Signed- --PRR (talk) 20:36, 13 September 2024 (UTC)

True about map projections, but the Venn section title here does say *Weird*. The Delaware/Pennsylvania arc is indeed "weird"; few other such arcs are found in regular map content, and the original story for it is indeed uncommon. Great Circle Parallel latitude "arcs" aren't weird in either way. 172.68.34.64 20:52, 13 September 2024 (UTC)

North-South lines are great-circle arcs, but non-equatorial East-West lines - as well as many diagonal ones - are minor-circle arcs (is that the right term?), just link the 12-Mile Circle. (Let's see if this retains my IP address from my top post.) 172.70.46.109 21:29, 13 September 2024 (UTC)

Right you are! 172.68.34.64 23:00, 14 September 2024 (UTC)

Great Blue Hole

There are two Great Blue Holes, one in Belize, one in Dahab, Egypt (Red Sea). 172.71.102.20 19:11, 13 September 2024 (UTC)

Recent Google Maps discovery

This may be inspired Joël Lapointe's very recently announced discovery of a 15km-diameter "pit" he found near Marsal Lake (Quebec) using Google Maps. "He saw a suspicious pit on Google Maps. Experts say it could be a crater from an ancient space rock" 172.69.64.185 20:10, 13 September 2024 (UTC)

man, why are so many of these in Quebec? does it have a natural meteor/circle magnet? 172.68.174.232 01:11, 14 September 2024 (UTC)

New Column

I'm thinking about a new column or two: GPS coordinates (with an Open Earth link?) and a satellite image, or something. 172.71.102.76 03:27, 14 September 2024 (UTC)

The table seems incomplete without something like that. 172.69.34.172 22:50, 14 September 2024 (UTC)

Meta Reference: Venn Diagram Double Crater

No comment yet on the fact that the two circles in the Venn Diagram refer to craters and circles... 172.71.102.53 01:32, 15 September 2024 (UTC)

Geographic bias by meteorites or Randall?

Boy am I happy that I don't live in North or Central America, where 11 out of 13 "craters" are located... Mumiemonstret (talk) 07:44, 15 September 2024 (UTC)

Maybe over here (rightpondia, oceania, down-under and the cradle of humanity itself), we just cleaned them up easier (or messed them up badly) so they were less obvious. (c.f. Nördlingen.) Y'all over thataway, however, haven't had time to do anything too drastic to obscure them. ;) 172.70.163.48 14:10, 15 September 2024 (UTC)

Haha, yeah, that was also my first thought when I googled the places I didn't know: very America-centric by either Randall or meteorite or other circle-creating entities... And even the other 2 places are in English speaking places (yes, I know English isn't the official language of India, but still one of the most common)--Lupo (talk) 04:28, 16 September 2024 (UTC)

I am tickled pink that two significant items in my life appear adjacent in this diagram: Stonehenge, and Crater Lake. My company name is Stonehenge (and I've been to the real rock pile a few times), and I'm a native Oregonian, using Crater Lake as my video-call background.

Crater Lake

So we're not going to talk about Crater Lake not being an actual crater? 172.69.134.107 (talk) 22:12, 16 September 2024 (please sign your comments with ~~~~)
