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 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)
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)
