Jim, there are currently 138 volcanoes claimed as known beneath the West Antarctic Ice Sheet alone. There are strongly suspected areas of volcanic activity beneath the East Antarctic Ice Sheet as well, but this region has been much less studied overall. The figure of 138 volcanoes is from Wikipedia's Geography of Antarctica page, an order of magnitude that other sources confirm at least. There are also numerous surface volcanoes on and around Antarctica, aside from places such as the famous Mount Erebus.

The map(s) shown here are from the BEDMAP 2 survey project conducted by the British Antarctic Survey in recent years (you can access a much enlarged version of of the first map shown by WeathermanSweden on the linked page). It's also worth reviewing at least the first map (Fig 1) in a paper available for free PDF download via ResearchGate The glacial geomorphology of the Antarctic ice-sheet bed, because this shows both the current coastline (black outline) and the rebounded one Loopysue was talking about (white outline). The latter confirms Antarctica sans ice would indeed be a substantial "new" solid landmass to explore, along with some significant islands of many sizes across much of what's now called West Antarctica.

So far as I can tell, there's nothing actually on the MAP BORDER sheet currently (apart from the usual automatically-generated pin items that retain a sheet in the map file).

The brown frame for the map is on the cave floor1 sheet, however, as is the brown piece of flooring on the right side of the map, and I think this may be the problem. There is nothing else on that sheet, however.

Hide all the sheets except cave floor1. That way you can move the brown frame to the MAP BORDER sheet, which will leave the patch of brown floor on cave floor1.

It's always as well to remember to check the information lines on the CC3+ page when you have a symbol ready to place, to be sure which sheet and layer it'll be placed on. You can always change those before or after you place it, though if afterwards, remember to do so! I usually forget to check the layer, as this doesn't always change automatically with symbols...

Also, when selecting anything, always keep an eye on the Command Line (lower left screen corner of the CC3+ window), just to make sure you haven't selected two things when you only wanted one. That's saved me any number of times, certainly.

What Sue said! (Beat me to it, Sue, as I was almost ready to post my own notes!)

Plus, if you open one of the example maps from this CA28 style, you'll see there are seven such points on the TEMPLATE layer, so there'll probably be more lurking elsewhere on yours, probably behind what you've already drawn, in the area you didn't select.

Indeed yes, very well done to all our winners - and to everyone who took part, regardless of the results.

Perhaps the most important achievement of all is the great contribution made to increasing the coverage of maps in the Atlas.

Onward now to the Atlas Map 2,000 competition 😁!

I remembered this because I used it a long while back (shown in the first post in that link) to make versions of Nibirum for the Community Atlas!

Just caught-up with the livestream VOD, and while obviously disappointed that Ralf didn't go with the peppermint volcano options (or early varicolor test if you prefer), it is a fun drawing!

Slightly weird that the VOD continued on through what was a break in transmission for the live viewers, but that's what happens when you're broadcasting from a strobing disco, as Ralf was 😉. Hopefully, whatever was causing that effect can be resolved before next time, as it was a little distracting at times.

I could have done with these hive symbols 2½ years ago, when I was preparing my giant ant nest map for the Community Atlas (Queen Mica's Scintillant Palace - Forum topic and Atlas link)!

Tomorrow it was - just resubbed!

Yes, that's it Sue. It helps make the water texture look more like broad-scale ocean waves, and the land textures more like the smaller-scale surface undulations you find there, at least to my eye/mind.

[Now just wait for the chorus of disapproval from everyone else 😉]

The original has a fascinatingly "windblown", swirling vibe to it overall.

And as someone who often copy-traces by hand/mouse scanned hand-drawn maps into CC3+, the tenacity to make such things a reality is something I can readily appreciate!
